+ # LTX-2.5 β€” turnkey SceneWorks MLX and Candle bundle
23
+
24
+ This is the pinned, token-free model bundle used by [SceneWorks](https://github.com/SceneWorks/SceneWorks) for native LTX-2.5 generation. It contains the complete split LTX-2.5 pipeline at q4, q8, and bf16, both distilled and guided dev transformers, the shipped distilled rank-450 adapter, and the separately staged stock Gemma 4 prompt enhancer. A fresh SceneWorks install downloads these ready-to-run files; no in-app conversion or access to the gated source repositories is required.
25
+
26
+ ## Repository layout
27
+
28
+ | path | contents |
29
+ |---|---|
30
+ | `distilled/q4/`, `distilled/q8/`, `distilled/bf16/` | Complete distilled LTX-2.5 tier: transformer, self-contained Gemma 4 text encoder, connector, Conv VAE, DiffVAE, spatial and temporal upsamplers, duration head, audio VAE, vocoder, and split manifests. |
31
+ | `dev/q4/`, `dev/q8/`, `dev/bf16/` | The same complete tier with the guided 30-step dev transformer. Distilled remains the SceneWorks default. |
32
+ | `distilled_lora/` | Upstream LTX-2.5 distilled LoRA, with rank and alpha read from its safetensors metadata. |
33
+ | `enhancer/` | Stock `google/gemma-4-12B-it` snapshot used only for opt-in T2V/I2V prompt enhancement. The tier-local self-contained text encoder remains the generation encoder. |
34
+ | `licenses/` | LTX-2.x Community License Agreement (August 11, 2026), Apache License 2.0, the Gemma Prohibited Use Policy, and provenance notice. |
35
+
36
+ Each tier is an indivisible pipeline contract: q4/q8/bf16 selects the matching representation for every quantizable segment. The tier's `split_model.json` records component identities and quantization; SceneWorks rejects incomplete or mismatched layouts.
37
+
38
+ ## Provenance and modifications
39
+
40
+ - LTX-2.5 components and the distilled LoRA derive from [Lightricks/LTX-2.5](https://huggingface.co/Lightricks/LTX-2.5) and the [LTX-2 v1.2.0 reference](https://github.com/Lightricks/LTX-2/tree/v1.2.0). SceneWorks converted and, where selected, quantized the components into the native split MLX/Candle layout; generative model behavior was not fine-tuned.
41
+ - The dev transformer derives from the LTX-2.5 dev checkpoint and is packed through the same converter into q4/q8/bf16.
42
+ - `enhancer/` mirrors the stock [google/gemma-4-12B-it](https://huggingface.co/google/gemma-4-12B-it) snapshot for offline-only prompt enhancement.
43
+ - Hugging Face `extra_gated_*` repository metadata is intentionally absent. Removing the hosting-service click-through does not alter any license or use restriction included here.
44
+
45
+ ## Licenses
46
+
47
+ This repository contains components governed by separate terms:
48
+
49
+ - LTX-2.5 weights, derivatives, and the distilled adapter: [LTX-2.x Community License Agreement](licenses/LTX-2-Community-License.txt), license date August 11, 2026. The agreement includes use restrictions and commercial licensing conditions and must travel with redistributed derivatives.
50
+ - Gemma 4 text-encoder/enhancer weights: [Apache License 2.0](licenses/Apache-2.0.txt), with Google's [Gemma Prohibited Use Policy](licenses/Gemma-Prohibited-Use-Policy.txt) also reproduced here.
51
+ - [NOTICE](licenses/NOTICE.txt) records the exact sourcing and the material difference from the Gemma 1–3 Terms of Use used by the older LTX-2.3 bundle.
52
+
53
+ Downloading, using, modifying, or redistributing a component requires compliance with all terms applicable to that component.

114
+ documentation, if provided along with the Derivative Works; or,
115
+ within a display generated by the Derivative Works, if and
116
+ wherever such third-party notices normally appear. The contents
117
+ of the NOTICE file are for informational purposes only and

+ as modifying the License.
123
+
124
+ You may add Your own copyright statement to Your modifications and
125
+ may provide additional or different license terms and conditions
126
+ for use, reproduction, or distribution of Your modifications, or
127
+ for any such Derivative Works as a whole, provided Your use,

129
+ the conditions stated in this License.
130
+
131
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
132
+ any Contribution intentionally submitted for inclusion in the Work
133
+ by You to the Licensor shall be under the terms and conditions of
134
+ this License, without any additional terms or conditions.
135
+ Notwithstanding the above, nothing herein shall supersede or modify
136
+ the terms of any separate license agreement you may have executed
137
+ with Licensor regarding such Contributions.
138
+
139
+ 6. Trademarks. This License does not grant permission to use the trade
140
+ names, trademarks, service marks, or product names of the Licensor,

+ except as required for reasonable and customary use in describing the
142
+ origin of the Work and reproducing the content of the NOTICE file.
143
+
144
+ 7. Disclaimer of Warranty. Unless required by applicable law or
145
+ agreed to in writing, Licensor provides the Work (and each
146
+ Contributor provides its Contributions) on an "AS IS" BASIS,
147
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148
+ implied, including, without limitation, any warranties or conditions
149
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150
+ PARTICULAR PURPOSE. You are solely responsible for determining the
151
+ appropriateness of using or redistributing the Work and assume any
152
+ risks associated with Your exercise of permissions under this License.
153
+
154
+ 8. Limitation of Liability. In no event and under no legal theory,
155
+ whether in tort (including negligence), contract, or otherwise,
156
+ unless required by applicable law (such as deliberate and grossly
157
+ negligent acts) or agreed to in writing, shall any Contributor be
158
+ liable to You for damages, including any direct, indirect, special,
159
+ incidental, or consequential damages of any character arising as a
160
+ result of this License or out of the use or inability to use the
161
+ Work (including but not limited to damages for loss of goodwill,
162
+ work stoppage, computer failure or malfunction, or any and all
163
+ other commercial damages or losses), even if such Contributor
164
+ has been advised of the possibility of such damages.
165
+
166
+ 9. Accepting Warranty or Additional Liability. While redistributing
167
+ the Work or Derivative Works thereof, You may choose to offer,
168
+ and charge a fee for, acceptance of support, warranty, indemnity,
169
+ or other liability obligations and/or rights consistent with this
170
+ License. However, in accepting such obligations, You may act only
171
+ on Your own behalf and on Your sole responsibility, not on behalf
172
+ of any other Contributor, and only if You agree to indemnify,
173
+ defend, and hold each Contributor harmless for any liability
174
+ incurred by, or claims asserted against, such Contributor by reason
175
+ of your accepting any such warranty or additional liability.

+ Gemma Prohibited Use Policy
2
+ ============================
3
+
4
+ Google reserves the right to update this Gemma Prohibited Use Policy from
5
+ time to time. Last modified: February 21, 2024.
6
+
7
+ Source: https://ai.google.dev/gemma/prohibited_use_policy
8
+
9
+ This policy applies to "Gemma" (the set of machine learning language models,
10
+ trained model weights and parameters Google publishes under the Gemma
11
+ program) and to "Model Derivatives" of it. The policy text itself is
12
+ undated-per-release and generic β€” it does not name a specific Gemma version
13
+ or scope itself to a particular license. SceneWorks conservatively applies
14
+ it to the bundled Gemma-4-12B text encoder as well: it continues to sit
15
+ alongside Gemma 4 in Google's own documentation even though Gemma 4 is
16
+ licensed under the Apache License 2.0 rather than Google's earlier, more
17
+ restrictive Gemma Terms of Use (see Apache-2.0.txt in this directory, and
18
+ the accompanying NOTICE.txt for why that distinction matters for LTX-2.5).
19
+
20
+ You may not use nor allow others to use Gemma or Model Derivatives to:
21
+
22
+ 1. Generate any content, including the outputs or results generated by
23
+ Gemma or Model Derivatives, that infringes, misappropriates, or
24
+ otherwise violates any individual's or entity's rights (including, but
25
+ not limited to rights in copyrighted content).
26
+
27
+ 2. Perform or facilitate dangerous, illegal, or malicious activities,
28
+ including:
29
+ - Facilitation or promotion of illegal activities or violations of
30
+ law, such as: promoting or generating content related to child
31
+ sexual abuse or exploitation; promoting or facilitating sale of, or
32
+ providing instructions for synthesizing or accessing, illegal
33
+ substances, goods, or services; facilitating or encouraging users
34
+ to commit any type of crimes; or promoting or generating violent
35
+ extremism or terrorist content.
36
+ - Engagement in the illegal or unlicensed practice of any vocation or
37
+ profession including, but not limited to, legal, medical,
38
+ accounting, or financial professional practices.
39
+ - Abuse, harm, interference, or disruption of services (or enable
40
+ others to do the same), such as: promoting or facilitating the
41
+ generation or distribution of spam; or generating content for
42
+ deceptive or fraudulent activities, scams, phishing, or malware.
43
+ - Attempts to override or circumvent safety filters or intentionally
44
+ drive Gemma or Model Derivatives to act in a manner that
45
+ contravenes this Gemma Prohibited Use Policy.
46
+ - Generation of content that may harm or promote the harm of
47
+ individuals or a group, such as: generating content that promotes
48
+ or encourages hatred; facilitating methods of harassment or
49
+ bullying to intimidate, abuse, or insult others; generating content
50
+ that facilitates, promotes, or incites violence; generating content
51
+ that facilitates, promotes, or encourages self harm; generating
52
+ personally identifying information for distribution or other
53
+ harms; tracking or monitoring people without their consent;
54
+ generating content that may have unfair or adverse impacts on
55
+ people, particularly impacts related to sensitive or protected
56
+ characteristics; or generating, gathering, processing, or inferring
57
+ sensitive personal or private information about individuals
58
+ without obtaining all rights, authorizations, and consents
59
+ required by applicable laws.
60
+
61
+ 3. Generate and distribute content intended to misinform, misrepresent or
62
+ mislead, including: misrepresentation of the provenance of generated
63
+ content by claiming content was created by a human, or represent
64
+ generated content as original works, in order to deceive; generation of
65
+ content that impersonates an individual (living or dead) without
66
+ explicit disclosure, in order to deceive; misleading claims of
67
+ expertise or capability made particularly in sensitive areas (e.g.
68
+ health, finance, government services, or legal); making automated
69
+ decisions in domains that affect material or individual rights or
70
+ well-being (e.g., finance, legal, employment, healthcare, housing,
71
+ insurance, and social welfare); generation of defamatory content,
72
+ including defamatory statements, images, or audio content; or engaging
73
+ in the unauthorized or unlicensed practice of any profession including,
74
+ but not limited to, financial, legal, medical/health, or related
75
+ professional practices.
76
+
77
+ 4. Generate sexually explicit content, including content created for the
78
+ purposes of pornography or sexual gratification (e.g. sexual chatbots).
79
+ Note that this does not include content created for scientific,
80
+ educational, documentary, or artistic purposes.

+ 2. The public github.com/Lightricks/LTX-2 repository, tag v1.2.0
24
+ (commit d151147788a9284cca791edc6ce898007e727fe6, verified via
25
+ `GET /repos/Lightricks/LTX-2/git/refs/tags/v1.2.0` β€” the tag resolves
26
+ to that exact commit), file LICENSE.md. Fetched
27
+ 2026-08-18 from
28
+ https://raw.githubusercontent.com/Lightricks/LTX-2/v1.2.0/LICENSE.md.
29
+ Its heading is "License date: August 11, 2026", matching the model
30
+ card and the story's measured metadata.
31
+
32
+ LTX-2-Community-License.txt reproduces that text with only Markdown
33
+ formatting characters (`**`, `>`, `[text](url)`) stripped for plain-text
34
+ display in the About screen's `<pre>` block; no wording was changed.
35
+
36
+ Diff against LTX-2.3's bundled license (required by sc-18785)
37
+ ---------------------------------------------------------------
38
+ LTX-2.3's bundled text (../ltx-2.3/LTX-2-Community-License.txt) is headed
39
+ "License date: January 5, 2026" β€” a different, earlier version. Comparing
40
+ the two verbatim texts: they are NOT the same agreement reworded for a new
41
+ date. The August 11, 2026 (LTX-2.5) text differs from the January 5, 2026
42
+ (LTX-2.3) text in substance, not just date:
43
+
44
+ - New Section 3.5 "Transfer of Derivatives" β€” an entirely new clause
45
+ requiring downstream transferees of a Derivative (including LoRA
46
+ adapters) to independently obtain a paid license if they are a
47
+ Commercial Entity, regardless of who created the Derivative. LTX-2.3's
48
+ Section 3 has no equivalent.
49
+ - Section 6 "Updates and Runtime Restrictions" is retitled "Updates and
50
+ Runtime Restrictions; AI Regulations" and gains ~2 paragraphs of new
51
+ obligations: compliance with the EU AI Act (Regulation (EU) 2024/1689)
52
+ and the California AI Transparency Act, a duty to preserve
53
+ watermarking/content-provenance/latent-disclosure features, an
54
+ indemnification clause for AI-regulation violations, and a new
55
+ paragraph on the EU AI Act Article 53(2) free/open-source derogation.
56
+ LTX-2.3's Section 6 is four sentences with none of this.
57
+ - Section 14 "Disputes and Arbitration" gains an explicit jury-trial /
58
+ class-action waiver heading and a new consumer-protection carve-out
59
+ (EU/UK/California mandatory consumer law is preserved), splitting what
60
+ was LTX-2.3's single Section 14/15 into three numbered
61
+ sections (14, 15, 16) in the 2.5 text.
62
+ - Both versions already share the same $10,000,000 annual-revenue
63
+ Commercial Entity threshold (Section 2.1) and the same 20-item
64
+ Attachment A use restrictions (items 19-20, on circumventing technical
65
+ limitations and on competing products, are present in BOTH β€” this was
66
+ not new to 2.5).
67
+
68
+ Conclusion: the two licenses are meaningfully different documents, not a
69
+ reused/re-dated copy. Both are shipped as separate, complete texts (this
70
+ directory for 2.5, ../ltx-2.3/ for 2.3) rather than deduplicating one into
71
+ the other.
72
+
73
+ Gemma 4 text encoder β€” NOT the same license family as LTX-2.3's Gemma 3
74
+ --------------------------------------------------------------------------
75
+ LTX-2.3 bundles a Gemma-3-12B-IT text encoder under Google's restrictive
76
+ Gemma Terms of Use (see ../ltx-2.3/Gemma-Terms.txt). The story description
77
+ for this ticket assumed LTX-2.5's Gemma-4-12B encoder carries the same
78
+ restrictive terms. Verified directly against Google's own pages (fetched
79
+ 2026-08-18, two independent URLs, cross-checked against raw HTML β€” not just
80
+ a page summary) that assumption is WRONG for Gemma 4:
81
+
82
+ - https://ai.google.dev/gemma/terms (the page governing Gemma 1/1.1/2/3/3n)
83
+ itself states: "For Gemma 4 terms, see the Gemma 4 license" and links to
84
+ https://ai.google.dev/gemma/apache_2.
85
+ - https://ai.google.dev/gemma/apache_2 is titled "Apache License 2.0" and
86
+ contains the complete, unmodified Apache License 2.0 text β€” Google
87
+ licenses Gemma 4 model weights under Apache-2.0, not the Gemma Terms of
88
+ Use that govern Gemma 1-3.
89
+ - The separate Gemma Prohibited Use Policy
90
+ (https://ai.google.dev/gemma/prohibited_use_policy, last modified
91
+ February 21, 2024, generic across all Gemma releases) still applies to
92
+ Gemma 4 as an acceptable-use layer on top of Apache-2.0 β€” Google's own
93
+ nav places it under the same "Gemma" section regardless of which
94
+ license (ToU or Apache) a given release uses.
95
+
96
+ Practical effect: LTX-2.5's Gemma-4-12B component is documented here with
97
+ Apache-2.0.txt (the permissive grant) plus Gemma-Prohibited-Use-Policy.txt
98
+ (the still-applicable use policy) β€” two documents, not the single
99
+ restrictive Gemma-Terms.txt notice used for 2.3's Gemma 3. This is a
100
+ narrower, more permissive obligation than 2.3 carries, but it is still a
101
+ distinct, tracked notice: Apache-2.0 requires retaining attribution and the
102
+ NOTICE contents on redistribution, and the Prohibited Use Policy is a real,
103
+ enforceable restriction layered on top of that permissive grant.
104
+
105
+ Degated-mirror plan does not misrepresent the terms
106
+ ------------------------------------------------------
107
+ SceneWorks/ltx-2.5-mlx (like SceneWorks/ltx-2.3-mlx before it) strips
108
+ Hugging Face's `extra_gated_*` repo metadata when it rehosts the weights.
109
+ That metadata only drives HF's own click-through acceptance UI (the "Agree
110
+ and access repository" gate); it is not part of the license terms
111
+ themselves, which live in `__metadata__.license` and the model card's
112
+ `license` tag and are reproduced verbatim in this directory. Removing the
113
+ click-through does not remove, weaken, or amend any clause of the LTX-2.x
114
+ Community License Agreement, the Apache-2.0 grant, or the Gemma Prohibited
115
+ Use Policy β€” all three continue to bind users of the rehosted weights
116
+ exactly as they bind users of the upstream gated repos, and this repo's
117
+ About β†’ Licenses screen is precisely how SceneWorks surfaces that binding
118
+ obligation in place of HF's UI gate.
