The latest AI news and updates of Black Forest Labs — Frontier AI lab building visual intelligence and the open-weight FLUX image generation models. Covering Black Forest Labs's latest launches and product updates from the past 90 days.
Black Forest Labs11h agoBlack Forest Labs released a comprehensive guide for training LoRAs on its FLUX 3 Image Klein model. The documentation details the full process, including dataset preparation, captioning, and checkpoint selection, using a vintage Halloween postcard style as a practical example. The guide utilizes the AI Toolkit to steer the model toward specific visual styles.
Black Forest LabsOct 22Black Forest Labs upgraded its FLUX Video Upscaler to support 4K resolution. The tool regenerates frames rather than interpolating pixels, offering Precise and Creative modes for detail control. It processes clips up to 20 seconds and 50 MB, billing per megapixel-second of output. BFL reports the tool is twice as fast as Topaz Astra 2.
Black Forest LabsOct 15Black Forest Labs released FLUX 3 Image Klein, a 5.6B-parameter open-weights model for text-to-image, editing, and multi-reference generation. It runs on consumer GPUs with 8GB VRAM, supporting native 4K, bounding boxes, and pixel-perfect editing. Internal evaluations show it outperforming Qwen Image 2.1 in text-to-image and multi-reference tasks. The model is available via Hugging Face and the BFL API.
Black Forest LabsOct 14Black Forest Labs optimized FLUX 3 Video, delivering up to 2x faster speeds and 50% lower costs for native 2K and 4K generation. These improvements result from reduced compute requirements for serving. The company also reports that its 4K output now outperforms Kling o3 in quality at comparable pricing and latency.
Black Forest LabsOct 6Black Forest Labs' FLUX 3 model ranks #1 on Google DeepMind's Physics-IQ benchmark for physical world understanding. The model outperforms other frontier video models, including Gemini Omni 1.1 Flash and Sora 2, across tests like fluid dynamics and optics. This physics-based backbone powers the physically accurate motion in FLUX 3 Video and the action prediction in FLUX 3 Action.
Black Forest LabsSep 23Black Forest Labs released FLUX 3 Action, an open-weights 7B World Action Model that jointly predicts video and robot actions. It outperforms the previous best open model on the RoboLab benchmark by 6.1 percentage points, using 56% fewer parameters and running up to 3.95x faster. The model integrates into HuggingFace LeRobot for fine-tuning and edge deployment on NVIDIA Jetson.
Black Forest LabsSep 10Black Forest Labs launched FLUX Video Edit, a text-prompt tool for modifying existing video clips. The API supports adding, removing, or replacing objects, backgrounds, text, and dialogue with lip sync while preserving source length and framing. It processes 10-second clips in about 50 seconds at $0.03 per second of output, with 720p resolution.
Black Forest LabsAug 22Black Forest Labs released FLUX Video Upscale, a tool that regenerates video at up to 4K resolution with sharper faces and cleaner textures. It offers two modes: Precise for consistent identity and Creative for enhanced detail. The tool supports 1.5x, 2x, and 3x upscale factors and is available now through the Black Forest Labs API and playground.
Black Forest LabsAug 11Black Forest Labs reports that its FLUX 3 Video model reached the second spot on the Video Arena leaderboard with 1496 points. To mark the milestone, the company offers free access to the model in its playground until Sunday, August 16, at 11:59 PM PT. Upcoming updates include 4K resolution, video editing, and support for multiple reference inputs.
Black Forest LabsAug 4Black Forest Labs released FLUX 3 Video, a multimodal model generating 20-second clips at 1080p with native audio. The model supports text-to-video, image-to-video, and multilingual dialogue with lip-syncing. It introduces a Draft mode for fast previews at $0.06 per second, with full-quality rendering available at $0.17 per second. 2K, 4K, and open-weight versions are planned for future release.
