A new quantized version of the Segment Anything Model (SAM) 3.1 has been released, offering INT8 and INT4 formats. These quantized versions significantly reduce the model's size, with INT4 being nearly 40% smaller than its fp16 counterpart, leading to substantial VRAM savings. While inference speed improvements are marginal, the mask quality remains nearly identical to the original model. AI
IMPACT Quantized models like SAM 3.1 INT4 can enable broader deployment on devices with limited VRAM, potentially increasing accessibility for AI-powered image segmentation tasks.
