# Compatibility Matrix
This page summarizes common model + optimization combinations.
For the canonical, code-level list of model IDs recognized by
`VideoGenerator.from_pretrained(...)`, see the registrations in
`fastvideo/registry.py` (`register_configs(...)` entries).
!!! note
The full STA integration in `fastvideo/` is archived from `main` and kept
in `sta_do_not_delete`:
https://github.com/hao-ai-lab/FastVideo/tree/sta_do_not_delete
We do this because we believe VSA is strictly better than STA for the
actively maintained `main` inference path.
The symbols used have the following meanings:
- ✅ = Full compatibility
- ❌ = No compatibility
- ⭕ = Does not apply to this model
## Models x Optimization
The `HuggingFace Model ID` can be passed directly to
`from_pretrained()`. FastVideo then uses model-specific default settings for
pipeline initialization and sampling.

**Note**: Wan2.2 TI2V 5B has some quality issues when performing I2V generation. We are working on fixing this issue.
***Lucy Edit Dev uses a non-commercial model license. FastVideo support is
focused on inference integration for video editing workflows.
`Sliding Tile Attn (Legacy Branch)` entries refer to the archived
`sta_do_not_delete` branch workflow, not active `main` inference wiring.
## Canonical Supported IDs
The authoritative source for model-ID recognition is
`fastvideo/registry.py`. If a model ID is registered there, FastVideo can
resolve default pipeline and sampling configuration for it.
**Note (GEN3C)**: The official `nvidia/GEN3C-Cosmos-7B` repo provides a raw
`model.pt` checkpoint. Use a Diffusers-format repo (for example,
`FastVideo/GEN3C-Cosmos-7B-Diffusers`) or convert locally with
`scripts/checkpoint_conversion/convert_gen3c_to_fastvideo.py`.
## Special requirements
### Sliding Tile Attention
- Full STA pipeline usage is on the archived branch:
https://github.com/hao-ai-lab/FastVideo/tree/sta_do_not_delete
- STA currently requires Hopper GPUs (H100s).
### TurboWan2.1 (TurboDiffusion)
- Uses TurboDiffusionPipeline with RCM scheduler for 1-4 step generation
- Requires SLA attention backend: `export FASTVIDEO_ATTENTION_BACKEND=SLA_ATTN`
- Uses `guidance_scale=1.0` (no classifier-free guidance)
### Matrix Game 2.0
- Image-to-video game world models with keyboard/mouse control input
- Three variants available: Base (universal), GTA, and TempleRun
- Each variant has different keyboard dimensions for control inputs
