SAM 3 (fp16)

A float16 copy of Meta's SAM 3 (Segment Anything Model 3) in Hugging Face Transformers format, used by Game Bot Creator to auto-label images on the user's own PC.

This is not an official Meta release and is not made, endorsed or supported by Meta. It is our conversion of the SAM 3 weights from facebook/sam3 (revision 3c879f39826c281e95690f02c7821c4de09afae7) to float16. Nothing else was changed: same architecture, same tokenizer and processor settings. Download size is about 1.7 GB instead of 3.4 GB; in our tests detection results matched the original.

Usage

import torch
from transformers import Sam3Processor, Sam3Model

model = Sam3Model.from_pretrained("GameBotCreator/sam3-fp16", torch_dtype=torch.float16).to("cuda")
processor = Sam3Processor.from_pretrained("GameBotCreator/sam3-fp16")

On CPU, load with torch_dtype=torch.float32 (the weights are upcast on load).

Credits

SAM 3 was created by Meta AI. See the original model card at facebook/sam3 and the paper and code at facebookresearch/sam3.
