Black Forest Labs open-weights FLUX 3 Image Klein: 4K generation and pixel-perfect editing on consumer GPUs
hyxon4 · reddit · 2026-10-15
Black Forest Labs announced the open weights release of FLUX 3 Image Klein, its most capable open weights image model to date.
Key points:
- Runs on consumer GPUs and laptops while retaining large-model features: native 4K generation, bounding boxes, and pixel-perfect editing
- Release includes a base model for fine-tuning, a distilled low-latency model, and FP8, NVFP4, and INT8 quantized versions
- Follows September's open weights release of FLUX 3 Action for robotics; both share the FLUX 3 backbone, with more family releases to come
- Builds on 2026's Self-Flow research (improved image/video/audio generation plus representations supporting robot control) and January's FLUX.2 [klein] family
