| ## 1. Definitions |
|
|
| - **"Personal Use"** means use by a natural person for their own learning, research, |
| teaching, experimentation, hobby projects or other non-commercial purposes, where such |
| use does **not** directly or indirectly generate commercial revenue and does **not** |
| provide paid services to third parties based on the Model. |
| - **"Commercial Use"** means any use for profit, any use in the business operations of a |
| for-profit entity, or any use that generates commercial revenue. This includes, without |
| limitation: internal production systems of a company, paid APIs or SaaS offered to third |
| parties, integration into paid products, advertising or commercial analytics, |
| client-facing delivery work, and any paid service built on the Model. |
| - **"You"** means the natural person or legal entity exercising rights under this License. |
| - **"Derivative Model"** means any model obtained by fine-tuning, continued training, |
| distillation, quantization, pruning, merging or otherwise modifying the Model. |
|
|
| ## 2. Free Grant: Personal Use |
|
|
| Subject to this License, **Personal Use is free of charge**, with no fee and no prior |
| application required. You may: |
|
|
| 1. download, install, run and copy the Model; |
| 2. modify the Model and create or train Derivative Models; |
| 3. use the Model freely in personal, non-commercial projects, including publicly |
| releasing your research results and demos. |
|
|
| ## 3. Paid Grant: Commercial Use |
|
|
| **Any Commercial Use requires prior written commercial authorization.** Commercial Use |
| without such authorization is not permitted. |
|
|
| Commercial licenses are negotiated based on scale of use, deployment model and term, and |
| may include custom terms. To obtain one, contact: |
|
|
| > **Business contact: novaweb6868@outlook.com** |
| > |
| > Please briefly state: your entity name, intended use case, expected volume or deployment |
| > scale, and whether redistribution rights are required. |
|
|
| Until you and the copyright holder reach a written agreement on commercial licensing, |
| this License grants you **no** right of Commercial Use. |
|
|
| ## 4. General Restrictions (applies to both Personal and Commercial Use) |
|
|
| Whether your use is Personal Use or commercially licensed, you must not: |
|
|
| 1. remove, obscure or alter copyright notices, license identifiers or attribution in the Model; |
| 2. use the Model or any Derivative Model for any activity that violates applicable laws |
| or regulations; |
| 3. use the Model to generate or distribute malicious code, fraudulent content, or content |
| that infringes the lawful rights of others; |
| 4. sublicense the Model or any Derivative Model to third parties under terms that conflict |
| with this License (except where redistribution rights are expressly granted in a |
| commercial license); |
| 5. claim original authorship of the Model, or make any promise or warranty on behalf of |
| the copyright holder. |
|
|
| ## 5. Licensing of Derivative Models |
|
|
| Derivative Models you create **remain subject to this License**; your modifications do not |
| remove them from its scope. Sections 2, 3 and 4 therefore apply equally to Derivative |
| Models: Personal Use is free, Commercial Use requires a paid license. When distributing a |
| Derivative Model you must include the full text of this License and prominently state that |
| it is built upon BaiHu-V1-Flash. |
|
|
| ## 6. Upstream License and Third-Party Components |
|
|
| The Model is an architectural retrofit and continued-pretraining product of |
| `Qwen/Qwen3-0.6B-Base` (Apache License 2.0). This License **only** governs the rights the |
| copyright holder holds in the portions newly added to the Model, and **does not alter** |
| the original license terms of upstream components. All use of the Model must also comply |
| with the licenses applicable to those upstream components. In the event of a conflict, |
| the upstream license prevails with respect to the upstream components. |
|
|
| ## 7. What Counts as Commercial Use |
|
|
| The following **are** Commercial Use and require authorization (this list is not |
| exhaustive): |
|
|
| - use in the business of a company, studio, sole proprietorship or other for-profit |
| entity, even if no fee is charged directly; |
| - delivering projects or deliverables that incorporate the Model to clients; |
| - use to generate content, products or services sold externally; |
| - offering a free service built on the Model while monetizing through advertising, |
| traffic diversion, data monetization or similar. |
|
|
| The following are **generally not** Commercial Use (final determination rests with the |
| copyright holder): |
|
|
| - personal study, coursework, or academic research that is publicly published; |
| - use by non-profit organizations for non-commercial purposes. |
|
|
| ## 8. Disclaimer of Warranty |
|
|
| **The Model is provided "AS IS", without warranty of any kind**, express or implied, |
| including but not limited to the warranties of merchantability, fitness for a particular |
| purpose, accuracy and non-infringement. You bear all risks and consequences arising from |
| your use of the Model. In no event shall the copyright holder be liable for any direct, |
| indirect, incidental, special or consequential damages arising from the use of, or |
| inability to use, the Model. The Model may produce inaccurate, biased or otherwise |
| inappropriate output; you are responsible for evaluating it and for the consequences. |
|
|
| ## 9. Termination |
|
|
| If you breach any term of this License, the rights granted to you under it **terminate |
| automatically**, without notice. Upon termination you must immediately stop using the |
| Model and delete all copies and Derivative Models. Sections 4, 5, 8 and 10 survive |
| termination. |
|
|
| ## 10. Governing Law and Dispute Resolution |
|
|
| The formation, validity, interpretation and dispute resolution of this License are |
| governed by the laws of the copyright holder's jurisdiction. The parties shall first seek |
| an amicable resolution of any dispute arising from this License. |
|
|
| ## 11. Changes to This License |
