# Compatibility Matrix
The table below shows every supported model and optimizations supported for them.

The symbols used have the following meanings:

- ✅ = Full compatibility
- ❌ = No compatibility

## Models x Optimization
The `HuggingFace Model ID` can be directly pass to `from_pretrained()` methods and FastVideo will use the optimal default parameters when initializing and generating videos.

**Note**: there are some known quality issues with Wan2.1 + Sliding Tile Attn. We are working on fixing this issue.

## Special requirements

### StepVideo T2V
- The self-attention in text-encoder (step_llm) only supports CUDA capabilities sm_80 sm_86 and sm_90

### Sliding Tile Attention
- Currently only Hopper GPUs (H100s) are supported.
