About these variants
Four precision levels are available for MOSS-Image (available for both the SFT and Base checkpoints), trading VRAM and speed against generation quality:
- BF16 — full-precision reference (~10 GB). Highest quality, largest footprint. Available as diffusers on the official OpenMOSS-Team/MOSS-Image-SFT and OpenMOSS-Team/MOSS-Image-Base Hugging Face repositories, and ComfyUI compatible models on the Comfy-Org/MOSS-Image Hugging Face repository.
- INT8 (W8A8) ConvRot — 8-bit weights + 8-bit activations (~5.4 GB). Near-lossless quality (mean relative error ~0.87%, cosine similarity ~1.0005 vs BF16), ~2× smaller than BF16, runs on INT8 tensor cores (RTX 30-series and up).
