Compatibility

This is an MLX export of FastVLM for Apple Silicon Macs. It includes the CoreML FastViTHD vision tower as fastvithd.mlpackage.

This repository is not a standard PyTorch Transformers checkpoint and is not intended for vLLM, SGLang, or Linux GPU inference.

Notes

This is an MLX-converted derivative of Apple FastVLM.

Please refer to the original Apple FastVLM repository and model card for license and usage conditions.
