+
40
+ "Derivative Works" shall mean any work, whether in Source or Object
41
+ form, that is based on (or derived from) the Work and for which the
42
+ editorial revisions, annotations, elaborations, or other modifications
43
+ represent, as a whole, an original work of authorship. For the purposes

+ excluding those notices that do not pertain to any part of
104
+ the Derivative Works; and
105
+
106
+ (d) If the Work includes a "NOTICE" text file as part of its

+ as modifying the License.
122
+
123
+ You may add Your own copyright statement to Your modifications and

+ reproduction, and distribution of the Work otherwise complies with
128
+ the conditions stated in this License.
129
+
130
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
131
+ any Contribution intentionally submitted for inclusion in the Work
132
+ by You to the Licensor shall be under the terms and conditions of
133
+ this License, without any additional terms or conditions.
134
+ Notwithstanding the above, nothing herein shall supersede or modify
135
+ the terms of any separate license agreement you may have executed
136
+ with Licensor regarding such Contributions.
137
+
138
+ 6. Trademarks. This License does not grant permission to use the trade
139
+ names, trademarks, service marks, or product names of the Licensor,

+ except as required for reasonable and customary use in describing the
141
+ origin of the Work and reproducing the content of the NOTICE file.
142
+
143
+ 7. Disclaimer of Warranty. Unless required by applicable law or
144
+ agreed to in writing, Licensor provides the Work (and each
145
+ Contributor provides its Contributions) on an "AS IS" BASIS,
146
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147
+ implied, including, without limitation, Any warranties or conditions
148
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149
+ PARTICULAR PURPOSE. You are solely responsible for determining the
150
+ appropriateness of using or redistributing the Work and assume any
151
+ risks associated with Your exercise of permissions under this License.
152
+
153
+ 8. Limitation of Liability. In no event and under no legal theory,
154
+ whether in tort (including negligence), contract, or otherwise,
155
+ unless required by applicable law (such as deliberate and grossly
156
+ negligent acts) or agreed to in writing, shall any Contributor be
157
+ liable to You for damages, including any direct, indirect, special,
158
+ incidental, or consequential damages of any character arising as a
159
+ result of this License or out of the use or inability to use the
160
+ Work (including but not limited to damages for loss of goodwill,
161
+ work stoppage, computer failure or malfunction, or any and all
162
+ other commercial damages or losses), even if such Contributor
163
+ has been advised of the possibility of such damages.
164
+
165
+ 9. Accepting Warranty or Additional Liability. While redistributing
166
+ the Work or Derivative Works thereof, You may choose to offer,
167
+ and charge a fee for, acceptance of support, warranty, indemnity,
168
+ or other liability obligations and/or rights consistent with this
169
+ License. However, in accepting such obligations, You may act only
170
+ on Your own behalf and on Your sole responsibility, not on behalf
171
+ of any other Contributor, and only if You agree to indemnify,
172
+ defend, and hold each Contributor harmless for any liability
173
+ incurred by, or claims asserted against, such Contributor by reason
174
+ of your accepting any such warranty or additional liability.

20
+ The **step-4000** CoCode-World task LoRA for **MiniMax-H3 Ref2VA**, trained on synchronized two-player GTA videos with Proxy555 control. The EMA weights are the ones used by the eight published 60-second evaluation examples.

28

+ ```bash
30
+ hf download iapple1/CoCode-World-Model --local-dir checkpoints/step-004000
31
+ ```
32
+
33
+ | File | Use |
34
+ |---|---|
35
+ | `ema.safetensors` | EMA task LoRA; recommended for inference (FP32 storage) |
36
+ | `lora.safetensors` | Non-EMA task LoRA at step 4000 (BF16 storage) |
37
+ | `optimizer.pt`, `rng_state.pt` | Saved training state for an exact optimizer resume with matching training data and configuration |
38
+ | `trainer_state.json` | Architecture, training settings, tensor names fingerprint and payload checksums |
39
+ | `model_manifest.json` | Release provenance and original checkpoint metadata hash |
40
+
41
+ These are native checkpoint tensors for the provided loader, not a standalone base model or a drop-in Diffusers `load_lora_weights` export. Download the official MiniMax-H3 model separately. Tensor files are unchanged; local paths in the trainer metadata were normalized for publication.
42
+
43
+ ## Training initialization
44
+
45
+ **First download the official [MiniMax-H3 weights](https://huggingface.co/MiniMaxAI/MiniMax-H3). Then download DiffSynth-Studio's released [Ref2VA DeCFG training adapter](https://www.modelscope.cn/models/DiffSynth-Studio/MiniMax-H3-TrainingAdapter).** Continue task training from that pretrained setup: fuse `model_ref2va.safetensors` into the frozen base at scale 1, then train a fresh rank-64 task LoRA. The training code verifies the exact DeCFG file checksum.
46
+
47
+ 训练前先下载 MiniMax-H3 官方权重,再下载 DiffSynth-Studio 开源的 Ref2VA DeCFG LoRA。训练时固定合入 DeCFG 预设,在此基础上训练 CoCode-World 的 rank-64 任务 LoRA。推理时加载原始 MiniMax-H3 和本仓库的任务 LoRA EMA;不合入训练用 DeCFG 预设。
48
+
49
+ The published checkpoint was trained with learning rate `1e-5`, 200 warmup steps, rank/alpha `64/64`, EMA decay `0.999`, CP8 × DP4 on 32 GPUs, and a target-row flow-matching objective. See `training_config.json` for the recorded configuration. The original run used 8,552 clips; the public 5,000-clip dataset is a curated subset and does not reproduce the exact original training trajectory.
50
+
51
+ ## Inference
52
+
53
+ Use the code repository's `scripts/evaluate.sh`. The eight examples include the actual edited first-frame input, all 17 window prompts, original Proxy555 input, seeds, and a compressed preview of the recorded result. Recorded inference used 30 denoising steps, 24 FPS, a 2560 × 720 output, 124-frame windows, 39-frame overlap, and 17 windows cropped to 60 seconds. This is the original task LoRA, not a DMD student.
54
+
55
+ ## License
56
+
57
+ The task adapter retains this repository's Apache-2.0 license. The MiniMax-H3 base model is separately governed by the [MiniMax-H3 Community License Agreement](https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/LICENSE). The training-only DeCFG adapter retains its upstream terms. No MiniMax-H3 base weights or DeCFG preset weights are redistributed here.
