Foundation-1 Model Loader
Loads a Foundation-1 model from a local .safetensors checkpoint. Auto-downloads from HuggingFace on first run if no model is present. The model is cached and only reloads when the checkpoint, device, or attention type changes.

Inputs (2)
| Name | Type | Default | Description |
|---|---|---|---|
| model | COMBO | Foundation-1 .safetensors checkpoint. If no model is found it will be downloaded automatically from huggingface.co/RoyalCities/Foundation-1 on first run. | |
| attention | COMBO | auto | 'auto' uses SageAttention if installed, otherwise SDPA. 'sdpa' enables all PyTorch SDPA backends (uses Flash internally if available). 'flash_attention_2' forces the Flash SDP backend only (CUDA only). 'sageattention' monkey-patches F.sdpa with SageAttention (CUDA only — requires: pip install sageattention). Changing this setting unloads and reloads the model. |
