# Update XTuner Supported Model Docs Keep the English and Chinese `model.md` files synchronized with the actual Config classes in `xtuner/v1/model/`. ## Scan the Codebase Run the bundled scan script from the xtuner project root to discover all Config classes and their inheritance: ```bash python3 .agents/skills/xtuner-sync-supported-models/scripts/scan_model_configs.py ``` The script outputs JSON with two keys: - `configs`: list of every `*Config` class under `xtuner/v1/model/` with its parent classes and file path - `children`: parent-to-children mapping for the hierarchy tree ## What to Update Compare the script output against the two files: - `docs/en/pretrain_sft/advanced_tutorial/model.md` - `docs/zh_cn/pretrain_sft/advanced_tutorial/model.md` Both files share the same structure and must stay in sync: 1. **Base Config Classes** — configs that directly inherit from `TransformerConfig` (or `MoEConfig`) and provide a `from_hf` classmethod for loading HuggingFace weights 2. **Concrete Model Configs** — fixed-scale subclasses of the base configs above 3. **Compose Models** — multimodal configs that inherit from `BaseComposeConfig` 4. **Inheritance Hierarchy** — a text tree showing the full `XTunerBaseModelConfig` hierarchy ### Rules for the Base Config table Include these direct descendants of `TransformerConfig`/`MoEConfig`: - `Qwen2DenseConfig` - `Qwen3DenseConfig` - `DeepSeekV3Config` - `GptOssConfig` - `Qwen3MoEConfig` Exclude from the base table: - `MoEConfig` — it is an intermediate base class, not a usable model family - `Qwen3_5_VLTextMoEConfig` — it is an intermediate base with only one concrete child; its child `Qwen3_5_VLTextMoE35BA3BConfig` belongs under the MoE concrete table ### Rules for the Concrete Model table Include every concrete subclass that has fixed parameter defaults. For each row note: - `Config Class` - `Base Class / Family` - `Architecture Type`: `Dense`, `MoE`, `Dense (VL backbone)`, `MoE (VL backbone)` - `Scale / Notes`: parameter count or total/activated size; for VL backbones note "for multimodal" `DeepSeekV3Config` appears here even though it has no separate base entry (it is both base and concrete). ### Rules for the Compose Models section Include three sub-tables: 1. **Compose Base Config Classes** — `Qwen3VLBaseConfig`, `InternVLBaseConfig`, `InternS1BaseConfig` - `Qwen3VLBaseConfig`: VL model based on Qwen3 text backbone - `InternVLBaseConfig`: VL model based on InternViT + Qwen3 - `InternS1BaseConfig`: Science multimodal model based on InternViT + Qwen3 2. **Concrete Compose Model Configs** — every subclass of the above bases; for each row note the wrapped `Text Config` and scale ### Rules for the Inheritance Hierarchy tree Rebuild the tree from `XTunerBaseModelConfig` with two top-level branches: ```text XTunerBaseModelConfig ├── TransformerConfig │ ├── Dense Models │ │ ├── Qwen2DenseConfig │ │ │ └── Qwen2Dense7BConfig │ │ └── Qwen3DenseConfig │ │ ├── Qwen3Dense8BConfig │ │ │ └── Qwen3VLTextDense8BConfig │ │ ├── Qwen3Dense4BConfig │ │ │ └── Qwen3VLTextDense4BConfig │ │ └── Qwen3Dense0P6BConfig │ └── MoE Models (via MoEConfig) │ ├── DeepSeekV3Config │ ├── GptOssConfig │ │ ├── GptOss21BA3P6Config │ │ └── GptOss117BA5P8Config │ ├── Qwen3MoEConfig │ │ ├── Qwen3MoE30BA3Config │ │ │ └── Qwen3VLTextMoE30BA3Config │ │ ├── Qwen3MoE235BA22Config │ │ │ └── Qwen3VLTextMoE235BA22Config │ │ └── Qwen3MoEFoPEConfig │ └── Qwen3_5_VLTextMoEConfig │ └── Qwen3_5_VLTextMoE35BA3BConfig └── BaseComposeConfig ├── Qwen3VLBaseConfig │ ├── Qwen3VLMoE30BA3Config │ ├── Qwen3VLMoE235BA22Config │ ├── Qwen3VLDense4BConfig │ ├── Qwen3VLDense8BConfig │ └── Qwen3_5_BaseConfig │ └── Qwen3_5_VLMoE35BA3Config ├── InternVLBaseConfig │ ├── InternVL3P5Dense8BConfig │ ├── InternVL3P5MoE30BA3Config │ └── InternVL3P5Dense1BConfig └── InternS1BaseConfig ├── InternS1Config └── InternS1MiniConfig ``` When new configs are added, insert them into the appropriate branch following the same indentation style. ## Translation Notes Keep the Chinese `model.md` (`docs/zh_cn/...`) structurally identical to the English one. Translate: - Section headings - Table header cells - Description cells (e.g., "Image / Video + Text" → "图像/视频 + 文本") - Scale descriptions (e.g., "~7B parameters" → "约 7B 参数", "FoPE variant" → "FoPE 变体") Do **not** translate Config class names, file paths, or code identifiers.
