By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

If this is what you want to do, use the GNU Lesser General +Public License instead of this License. diff --git a/README.md b/README.md index 154df8298fab5ecf322016157858e08cd1bccbe1..e937811e23cd1c0e9d7e948467910d505531b0d8 100644 --- a/README.md +++ b/README.md @@ -1,3 +1,114 @@ --- -license: apache-2.0 +language: +- ja +license: gpl-2.0 +pipeline_tag: text-generation +tags: +- pytorch +- coreml +- japanese +- causal-lm +- contextual-reranking +- tiny-gpt --- + +# VimeML Tiny Japanese GPT v1 + +A frozen **7,386,624-parameter**, decoder-only Japanese language model for local contextual candidate reranking and short within-sentence continuation.

It does not perform kana conversion or dictionary lookup. Invalid/overlong candidates raise in this diagnostic wrapper; the application implementation retains the dictionary order on eligibility failure. + +The FP32 loader checks all bundle files and the included source fingerprints, restores the shared head, and uses `torch.load(..., weights_only=True)`. Keep the source, tokenizer and inference files together. `verify_release.py` checks every release file without loading a model; checksums detect altered bytes but are not a digital signature. + +## Candidate scoring + +Encode `context + candidate` jointly. Cancel the common token prefix across BOS+context and the jointly encoded candidate sequences, then sum original full-vocabulary log-softmax values over the remaining suffix. Do not add a candidate-final EOS. Ties preserve the original order. This token suffix likelihood is a scoring proxy, not exact string conditional probability. + +Deployment uses **pure LM scoring**; AzooKey retrieves kana candidates. The older FP32 `AzooKey score + 2 × LM sum` policy is a historical comparison, not the INT8 deployment policy. Quantization does not establish that λ=2 remains optimal. + +## Training and evaluation + +Training used nine local shards of [FineWeb2-Edu Japanese](https://huggingface.co/datasets/hotchpotch/fineweb-2-edu-japanese) and Japanese [Tatoeba](https://tatoeba.org/), cleaned, split into sentences, exactly deduplicated and grouped across 98%/1%/1% train/validation/test splits.

Candidate fixtures, causal and right-PAD checks passed, and the frozen pool hit counts above were preserved. Do not describe the model as numerically identical to FP32. + +An AJIMEE-text diagnostic reported mean KL(FP32‖INT8)≈0.00589, mean NLL 5.56698→5.57289 and position top-choice agreement 94.4%. These are means of per-example position means, not a corpus token-weighted aggregate. Text content was capped at 127 tokens plus BOS; the old report did not record truncation counts. Similar aggregate KL to a simulated INT8 recipe does not prove exact conversion equivalence.

Host memory increased by about 24.2MB and peaked at 74.8MB. These are not keyboard-extension latency or memory measurements. + +A separate 152.7 second manual real-keyboard recording produced 127 approximately 1 second samples: physical footprint peak 21.25MiB and private resident peak 51.922MiB. The user confirmed LM ranking and next-word suggestions; installed build/model hashes were not independently captured. Short spikes may have been missed, the tail still grew slowly, and long-session stability is not certified. The different memory metrics cannot be substituted for one another. No energy claim is made. + +## Intended use and limitations + +Japanese within-sentence reranking and short completion experiments, primarily for on-device input methods. The model is small, not instruction-tuned, and can repeat text, drift, truncate or invent facts. Outputs need product-level review; the fixed beam suite had only 10/20 prefixes with clearly natural suggestions in an AI review. These offline pool metrics do not measure application-wide accuracy or guarantee keyboard performance. + +Semantic near-duplicates and training overlap with public evaluation text have not been comprehensively audited. AJIMEE has been used for error analysis and is not a fresh blind test. Development labels and review came from AI, not native-speaker adjudication. Official benchmark context can cross sentences, while the client uses current-sentence context. Candidate coverage limits reranking accuracy. + +## License and attribution + +Model weights and the included VimeML code are released under **GNU GPL v2.0**, chosen by the author.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The source model, loader, scoring and conversion code are included under `source/`; no `trust_remote_code` or training checkpoint is needed. + +## Files and identity + +| Path | Contents | +| --- | --- | +| `inference/` | Unique FP32 state_dict, config, original SentencePiece model, token manifest and provenance manifest; no optimizer | +| `coreml/ios18-int8-block32/` | Original Core ML `.mlpackage` and manifest | +| `source/` | Frozen VimeML Python source, conversion scripts, configuration and unified requirements | +| `infer.py` | Read-only wrapper around the original fingerprint-checked loader, generation and scoring | +| `evaluation/summary.json` | Curated results and source report hashes, without benchmark texts or device traces | +| `RELEASE.json`, `SHA256SUMS.txt`, `verify_release.py` | Release inventory and local byte verification | + +- Source repository: [Voltline/VimeML](https://github.com/Voltline/VimeML), commit **@@SOURCE_COMMIT@@**. +- Inference manifest SHA256: `@@BUNDLE_SHA@@`. +- Core ML manifest SHA256: `@@COREML_SHA@@`. +- Tokenizer SHA256: `@@TOKENIZER_SHA@@`. +- Original training checkpoint SHA256: `@@CHECKPOINT_SHA@@`; the training checkpoint is not distributed here. + +The original manifests remain byte-for-byte intact. Their old absolute paths describe provenance, not paths required on a downloader's machine. Core ML conversion scripts evolved after the original experiment; the old manifest's script hash is retained. + +## Architecture and tokenization + +Pre-LayerNorm GPT with GELU, learned absolute positions and causal attention: vocabulary 16,384; context length 128; width 256; 4 layers; 4 heads; FFN width 1024. Input embedding and LM head share one parameter. There is no KV cache or sliding context. Each generation step recomputes the entire prefix. + +SentencePiece 0.2.1 unigram, identity normalization, whitespace preservation and byte fallback. PAD/UNK/BOS/EOS IDs are 0/1/2/3. The exact original `tokenizer.model` is required; retraining a tokenizer does not preserve this vocabulary binding. + +## Quick start: downloaded files + +Python ≥3.11. After downloading the repository, install the included unified requirements. Select the appropriate PyTorch build first if needed; do not use the PyTorch-only package index for the whole requirements file. The Darwin branch pins the original Core ML tool environment; no Core ML prediction occurs during FP32 inference. + +```sh +python -m pip install -r source/requirements.txt +python verify_release.py +python infer.py --prompt "今日は雨が降っているので、" --max-new-tokens 8 +python infer.py --prompt "雨が降っているので、" --candidate "傘を持っていく" --candidate "橋を渡っていく" +``` + +The second inference command ranks the supplied strings using the original contextual suffix logP sum. It does not perform kana conversion or dictionary lookup. Invalid/overlong candidates raise in this diagnostic wrapper; the application implementation retains the dictionary order on eligibility failure. + +The FP32 loader checks all bundle files and the included source fingerprints, restores the shared head, and uses `torch.load(..., weights_only=True)`. Keep the source, tokenizer and inference files together. `verify_release.py` checks every release file without loading a model; checksums detect altered bytes but are not a digital signature. + +## Candidate scoring + +Encode `context + candidate` jointly. Cancel the common token prefix across BOS+context and the jointly encoded candidate sequences, then sum original full-vocabulary log-softmax values over the remaining suffix. Do not add a candidate-final EOS. Ties preserve the original order. This token suffix likelihood is a scoring proxy, not exact string conditional probability. + +Deployment uses **pure LM scoring**; AzooKey retrieves kana candidates. The older FP32 `AzooKey score + 2 × LM sum` policy is a historical comparison, not the INT8 deployment policy. Quantization does not establish that λ=2 remains optimal. + +## Training and evaluation + +Training used nine local shards of [FineWeb2-Edu Japanese](https://huggingface.co/datasets/hotchpotch/fineweb-2-edu-japanese) and Japanese [Tatoeba](https://tatoeba.org/), cleaned, split into sentences, exactly deduplicated and grouped across 98%/1%/1% train/validation/test splits. There were 25,713,003 unique sentences and 25,185,368 training sentences. The tokenizer learned from 2 million sampled training sentences. + +One data pass, 196,853 updates and 573,295,237 prediction targets. The frozen best checkpoint's complete validation loss is 4.5415708951, perplexity 93.8380942. Fixed-subset validation selected the checkpoint; the test split was not used for training, checkpoint selection or tuning. No test perplexity is claimed. + +Reranking uses fixed N-best 20 AzooKey candidates, without injecting correct answers. [AJIMEE JWTD_v2/v1](https://github.com/azooKey/AJIMEE-Bench) has 200 cases and allows multiple accepted spellings. The synthetic development set has 137 reviewed cases. + +| Frozen pool | AzooKey original Top-1 | FP32 pure LM Top-1 / Top-5 | INT8 pure LM Top-1 / Top-5 | Pool coverage | +| --- | ---: | ---: | ---: | ---: | +| Development | 111/137 | 122/137 / 134/137 | 122/137 / 134/137 | 136/137 | +| AJIMEE | 87/200 | 124/200 / 151/200 | 124/200 / 151/200 | 162/200 | + +INT8 vs Windows FP32: development changes 119 complete rankings and 0 first choices; AJIMEE changes 163 complete rankings and 2 first choices, both between acceptable spellings. The original development compression report instead compares against uncompressed conservative Core ML: 118 complete rankings change. Equal hit counts do not mean equal scores or complete rankings. See the release summary for the separate baselines and hashes. + +## Core ML variant + +**Weight-only symmetric INT8, block size 32; FP32 computation; CPU_ONLY; minimum iOS 18.** It is not INT8 activation or arithmetic inference. Logical `.mlpackage` size is **8,077,801 bytes**. This is not compiled size, IPA size or resident memory. + +Input `input_ids`: INT32 `[1,T]`, 1≤T≤128. Output `logits`: FLOAT32 `[1,T,16384]`, full raw vocabulary logits. Only right-side PAD is supported. Shared embedding/head are retained. Use `.cpuOnly`; GPU/ALL paths for this package triggered a quantized-gather assertion in the client experiments. + +On Mac, compile manually for the target platform before integrating: + +```sh +xcrun coremlcompiler compile coreml/ios18-int8-block32/model.mlpackage compiled-int8 --deployment-target 18.0 +``` + +The INT8 model **fails the strict FP32 logits alignment gate** (maximum absolute difference about 3.66). Candidate fixtures, causal and right-PAD checks passed, and the frozen pool hit counts above were preserved. Do not describe the model as numerically identical to FP32. + +An AJIMEE-text diagnostic reported mean KL(FP32‖INT8)≈0.00589, mean NLL 5.56698→5.57289 and position top-choice agreement 94.4%. These are means of per-example position means, not a corpus token-weighted aggregate. Text content was capped at 127 tokens plus BOS; the old report did not record truncation counts. Similar aggregate KL to a simulated INT8 recipe does not prove exact conversion equivalence. Tested palette4 group16 degraded substantially and is not included. + +## Performance evidence and limits + +Recorded iPhone 16 Pro Max optimized CPU_ONLY **test-host App** results: approximately 14 candidate reranking p50 10.4ms/p95 12.7ms; next-word p50 5.8ms; T128 prediction 3.0ms. Host memory increased by about 24.2MB and peaked at 74.8MB. These are not keyboard-extension latency or memory measurements. + +A separate 152.7 second manual real-keyboard recording produced 127 approximately 1 second samples: physical footprint peak 21.25MiB and private resident peak 51.922MiB. The user confirmed LM ranking and next-word suggestions; installed build/model hashes were not independently captured. Short spikes may have been missed, the tail still grew slowly, and long-session stability is not certified. The different memory metrics cannot be substituted for one another. No energy claim is made. + +## Intended use and limitations + +Japanese within-sentence reranking and short completion experiments, primarily for on-device input methods. The model is small, not instruction-tuned, and can repeat text, drift, truncate or invent facts. Outputs need product-level review; the fixed beam suite had only 10/20 prefixes with clearly natural suggestions in an AI review. These offline pool metrics do not measure application-wide accuracy or guarantee keyboard performance. + +Semantic near-duplicates and training overlap with public evaluation text have not been comprehensively audited. AJIMEE has been used for error analysis and is not a fresh blind test. Development labels and review came from AI, not native-speaker adjudication. Official benchmark context can cross sentences, while the client uses current-sentence context. Candidate coverage limits reranking accuracy. + +## License and attribution + +Model weights and the included VimeML code are released under **GNU GPL v2.0**, chosen by the author.
