Black Forest Labs' FLUX 3 Image Klein is a 5.6B open-weights image model you can use for paid work if your business earns under $5M a year. It runs on 8 GB GPUs in ComfyUI and costs $0.009 per 1K image hosted. We tested its text rendering and editing.
FLUX 3 Image launched on 1 October with box-based layouts, ten references and 4K output. We tested its pixel-exact edit claim on BFL's own samples: 67.8-94.1% of pixels stay identical, and three of nine edits change areas far from the object.
Black Forest Labs shipped FLUX 3 on July 23, 2026, a single multimodal model that generates images, generates video with synchronized audio, and predicts physical action, all in one architecture.
