BEN2 becomes the new default local backend (clean cutouts, strong on hair/fur edges), with BiRefNet-HR available as a high-res/print alternate and U2Net kept as the lightweight fallback. Both are MIT-licensed and download weights from HuggingFace on first use (cached via the existing hf_cache bind mount), unlike U2Net/SAM which need an explicit download script. - config: new BG_REMOVAL_MODEL setting (default "ben2") - tools.py: remove-background-base64 now tries local backends in order (request.model override > BG_REMOVAL_MODEL > ben2/u2net), falling back to rembg's birefnet-general session as a last resort - requirements.gpu.txt / Dockerfile.gpu: add ben2 + transformers deps needed for the new backends, with a build-time smoke test for ben2 - frontend: model dropdown in the Remove Background dialog, threaded through api.js to the new request field Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Ro4PwQKvSc3CH19LSN21Ht
