| commandline argument | explanation |
|--------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `--opt-sdp-attention` | Faster speeds than using xformers, only available for user who manually install torch 2.0 to their venv. (non-deterministic)
| `--opt-sdp-no-mem-attention` | Faster speeds than using xformers, only available for user who manually install torch 2.0 to their venv. (deterministic, slight slower than `--opt-sdp-attention`)
| `--xformers` | Use [xformers](https://github.com/facebookresearch/xformers) library. Great improvement to memory consumption and speed. Will only be enabled on small subset of configuration because that's what we have binaries for. [Documentation](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Xformers) |
| `--opt-sdp-attention` | Faster speeds than using xformers. (non-deterministic)
| `--opt-sdp-no-mem-attention` | Faster speeds than using xformers. (deterministic, slightly slower than `--opt-sdp-attention` and uses more VRAM)
| `--xformers` | Use [xformers](https://github.com/facebookresearch/xformers) library. Great improvement to memory consumption and speed. Nvidia GPUs only. |
| `--force-enable-xformers` | Enables xformers above regardless of whether the program thinks you can run it or not. Do not report bugs you get running this. |
| `--opt-split-attention` | Cross attention layer optimization significantly reducing memory use for almost no cost (some report improved performance with it). Black magic. <br/>On by default for `torch.cuda`, which includes both NVidia and AMD cards. |
| `--disable-opt-split-attention` | Disables the optimization above. |
