Black Forest Labs expands Access to frontier Visual Intelligence with Open Weights release of FLUX 3 Image Klein. Building on the open weights release of FLUX 3 Action, the company continues to make its models available for developers and businesses to build on, customize, and deploy. FREIBURG, Germany, Oct. 15, 2026 (GLOBE NEWSWIRE) - Black Forest Labs (BFL), the frontier AI research lab building visual intelligence, today announced the open weights release of FLUX 3 Image Klein, its most capable open weights image model to date. FLUX 3 Image Klein provides the quality of a large frontier model with the customization and speed of open weights, runs on consumer GPUs and laptops, and retains features from the larger FLUX 3 Image model such as native 4K generation, bounding boxes, and pixel perfect editing. The release includes a base model for fine-tuning, a distilled model for low-latency generation, and quantized FP8, NVFP4, and INT8 versions. Following September's open weights release of FLUX 3 Action for robotics, today's release brings the company's latest research to core creative use cases, giving developers and businesses greater freedom to build, customize, and deploy visual AI. Making its research and technology available for others to build on is one of Black Forest Labs' founding principles. BFL has consistently released its research findings alongside open weight versions of its industry-leading FLUX models, enabling others to build on its advances. So far in 2026, the team has published its Self-Flow research and released open weights for the FLUX.2 [klein] family in January and FLUX 3 Action in September. Self-Flow improved generation across images, video, and audio, while helping models learn representations that can also support robot control. This research led to BFL's most capable model to date, FLUX 3, which brings multimodal generation and action prediction into a shared architecture. Today's release opens access to the creative capabilities of the same FLUX 3 backbone, with further open weights releases from the FLUX 3 family to follow. "By sharing our research openly, we created a global community of developers and creators who are helping to advance the field together," said Robin Rombach, co-founder and CEO of BFL. "FLUX 3 allows that community to adapt the same foundation to very different needs, from creative generation to robotics. Giving developers the models, research, and tools to do that is key to advancing visual intelligence." Opening Access to Visual Intelligence By releasing open weights, BFL puts its models in the hands of developers and enterprises to build on, customize, secure, and deploy independently. Teams with data sovereignty or local deployment requirements can evaluate and adapt the models on their own infrastructure. Each open weights release includes tools and support for adaptation alongside safeguards to reduce misuse. FLUX 3 Image Klein is BFL's most capable open weights image model to date. In BFL's internal evaluations, FLUX 3 Image Klein scores higher than current leading open weights image models in text-to-image, multi-reference generation, and image editing, while costing less through the company's API. At 5.6 billion parameters, it runs on consumer GPUs and laptops with as little as 8 GB of VRAM, and draws on FLUX 3's shared learning across images, video, and audio. Images contribute spatial detail; video adds motion and physical dynamics; and audio provides information about events and interactions. Together, these signals help the model learn how the visual world behaves. Leads in quality at a smaller model size. Extends the quality and speed frontier. The same research foundation extends to physical AI. Last month, BFL released FLUX 3 Action, a seven-billion-parameter open weight model for robotics that ranked No. 1 on Physics-IQ Verified and NVIDIA's RoboLab-120 benchmark, which evaluates robot models across 120 simulated manipulation tasks. By releasing the weights and a full technical report, BFL made those capabilities available for researchers and robotics teams to train, adapt, and build on. Accessing and Customizing FLUX 3 Image Klein The open weights release of FLUX 3 Image Klein builds on BFL's roots in image generation. Founded on the belief that visual intelligence starts with a pixel, BFL has been developing frontier, production-ready image models since 2024 that power creative tools across platforms including Adobe, Canva, Meta, and Microsoft. Open weights image models built by BFL's founding team, from the original Stable Diffusion to FLUX and their community derivatives, remain among the most widely adopted, with more than 640 million downloads on Hugging Face. FLUX 3 Image Klein gives developers a foundation they can adapt to their own applications. It supports text-to-image generation, image editing, and generation using multiple reference images. BFL is releasing both a base model for fine-tuning and research, and a step distilled version that generates images in fewer sampling steps, with open weights allowing teams to customize and run the models on their own infrastructure. The distilled version is also available through BFL's API, where it runs with BFL's prompt enhancement and pixel-level editing pipeline for production workloads. Support for Ostris's AI Toolkit at launch will help developers fine-tune the model using their own examples. The release will also be supported by developer tools and platforms including ComfyUI, Diffusers from Hugging Face, vLLM-Omni, and SGLang Diffusion, making it easier to customize and deploy. FLUX 3 Image Klein was trained on NVIDIA GB200 GPUs NVL72 and optimized for NVIDIA's accelerated computing platform. Developers can fine-tune it with NVIDIA NeMo AutoModel and run it locally on NVIDIA GeForce RTX GPUs with 8 GB or more of VRAM. Available under the FLUX Kommunity License, which allows free commercial use for individuals and companies with annual revenue under $5M, alongside research and non-commercial use. Larger organizations can deploy commercially through BFL's self-hosted licensing options or API. This flexibility is particularly valuable for enterprises seeking greater control over model behavior, data handling and deployment. Pairing Open Weights with Safety Standards In an effort to make AI technology both open and safe, BFL implements multiple safeguards throughout the model development lifecycle to combat misuse. These include dataset filters during pre-training to limit exposure to harmful content, and targeted fine-tuning during post-training to suppress harmful behaviors, making it progressively harder to elicit harmful content. For FLUX 3 Image Klein, BFL engaged its external safety partner Cinder to evaluate both model checkpoints ahead of release, demonstrating fewer vulnerabilities than other popular open weight models.

Black Forest Labs launches FLUX 3 Action robotics AI model. Black Forest Labs has released FLUX 3 Action, an open 7-billion-parameter robotics AI model that sets a new RoboLab-120 benchmark while running up to 3.95x faster than prior leading models. What happened. Black Forest Labs has launched FLUX 3 Action, an open robotics AI model that predicts the next physical action a robot should take based on live camera feed input. The model marks the company's entry into robotics, extending beyond its existing work in generative image and video AI. FLUX 3 Action is built as an open-world-action model, meaning it is designed to generalise across varied, unstructured environments rather than being tuned to a single task or setting. Despite a relatively compact architecture of seven billion parameters, Black Forest Labs reports that the model has set a new benchmark result on RoboLab-120, a standard test for evaluating robotic action models, while running up to 3.95 times faster than the previous leading model on that benchmark. Why it matters. The release signals a broader shift in applied AI: models that translate visual perception directly into physical action are moving from research labs toward more accessible, open deployment. A smaller parameter count paired with a benchmark-leading speed gain suggests robotics AI is following the same trajectory as language and image models - doing more with less compute, which lowers the barrier for organisations to experiment with embodied AI rather than relying solely on large, resource-intensive systems. For leaders overseeing automation, logistics, manufacturing or service robotics, this points to robotics AI becoming more practical to adopt and iterate on. Faster inference and an open model structure typically mean shorter development cycles for teams building or customising robotic systems, which could accelerate how quickly physical automation projects move from pilot to production. By the numbers. * 7 billion parameters make up the FLUX 3 Action model architecture. * 3.95 times faster performance than the previous top-performing model on the RoboLab-120 benchmark. * RoboLab-120 is the benchmark on which Black Forest Labs reports a new record result. The renascence take. It is easy to read this as a purely technical milestone, but the real story is about what becomes operationally feasible once a capable action model is both open and efficient. Speed and openness change who gets to build with this technology, not just what the technology can do. Most coverage of robotics AI fixates on raw capability, but the behavioral story is about access: when a high-performing model becomes lighter and openly available, smaller operators and service teams - not just well-resourced robotics labs - can start prototyping physical automation. The organisations that benefit won't be the ones with the biggest compute budgets, but the ones that treat this as a design problem first: mapping where a camera-driven action model actually improves a customer or employee workflow, rather than deploying robotics for its own sake. Teams should pilot narrowly, on a single well-defined physical task, before assuming open-world generalisation translates smoothly into their own operating environment.
