🏆 Community Heroes

A massive thank you to the community members who helped make this release possible:

• @NielsRogge, @yonigozlan, and the Hugging Face team: For integrating SAM3-LiteText into the Hugging Face API.
• @colinlin1982: For finding redundant original SAM3 weights in the efficient models and adding a trim script to reduce the model size. (Note: The new EfficientSAM3.1 models do not need to be trimmed).
• @clcl777: For adding multi-device support.
