Black Forest Labs has shipped FLUX.2, a full new family of image generation and editing models. The headline release is FLUX.2 [dev] — a 32-billion parameter open-weight model on HuggingFace under a non-commercial license — which the team claims is the most capable open-weight image generation and editing model available. FLUX.2 [pro] is available via API with state-of-the-art quality and up to 4MP editing, while FLUX.2 [klein] (Apache 2.0, smaller and faster) is coming soon. The standout new capability is multi-reference image inputs: you can feed in multiple source images and FLUX.2 preserves faces, products, and subjects when changing backgrounds, lighting, or pose. This makes it dramatically more useful for commercial workflows — branding, e-commerce, and character consistency in storytelling. The model also gains JSON-structured prompting for reliable output control. FLUX.1 was already the leading open image model; FLUX.2 extends that lead while simultaneously adding API tiers for teams who want to skip self-hosting. BFL is positioning against Midjourney, Ideogram, and Stability AI simultaneously.

Marble 1.1 and 1.1 Plus are the latest updates to World Labs' generative 3D world model, the flagship product from the spatial AI startup co-founded by Fei-Fei Li. The 1.1 release focuses on visual quality improvements: better lighting and contrast handling, reduction in common visual artifacts (flickering, geometry drift at scene edges), and more consistent object coherence across viewing angles. Marble 1.1 Plus introduces dynamic scale — the model's most significant capability expansion since launch. Previous generations produced worlds of fixed spatial extent; 1.1 Plus automatically analyzes scene complexity and expands world coverage by deploying up to five "dynamic cubes" in a single generation pass. The result is environments that fill out naturally across a larger footprint without requiring multiple generation runs or manual stitching. Target use cases include game environment prototyping, architectural visualization, and training data generation for robotics simulators. World Labs has positioned Marble as the world's first commercially available spatial intelligence product, and the 1.1 updates shipped April 7-8, 2026 via the marble.worldlabs.ai web app. The dynamic scale feature in 1.1 Plus is available on paid plans, while quality improvements in 1.1 apply across all tiers. The updates arrive as competition in AI 3D generation heats up from tools like Luma AI and TripoSG.
Reviewer scorecard
“Multi-reference image input is the killer feature here — consistent characters and product shots have been a massive pain point for anyone building generative workflows. FLUX.2 [dev] being open-weight means I can self-host this for clients who need privacy.”
“Dynamic scale in a single generation pass is the feature I've been waiting for. Having to stitch multiple fixed-extent generations together was the main workflow pain in Marble 1.0 for game environment prototyping. If 1.1 Plus delivers on the demo quality, it cuts 3D world prototyping time by an order of magnitude.”
“32B parameters requires serious GPU memory to run locally — this isn't a consumer model despite the 'open' framing. And 'non-commercial' on the dev weight limits its usefulness for most builders. Wait for [klein].”
“The demos are impressive but the generation-to-game-engine pipeline is still manual and lossy. You can't export clean meshes with proper LODs or collision geometry — it's a concept tool, not a production asset pipeline. Until you can import Marble output directly into Unity or Unreal with proper metadata, this stays in the 'cool demo' category for most game devs.”
“Multi-reference consistency is the bridge between generative AI and real commercial production workflows. This is the moment image gen stops being a toy for individual prompts and starts being infrastructure for brand-consistent content at scale.”
“Fei-Fei Li's bet that 3D spatial intelligence is the next fundamental modality is looking more plausible with each Marble update. Dynamic world generation at scale is a prerequisite for training embodied AI agents — Marble's real customer may be the robotics and simulation market, not game studios.”
“The multi-reference feature alone is worth shipping for. Consistent character faces across a series of images has been impossible in open models — now it's built in. This changes how I approach any illustration or branding project.”
“For concept artists and production designers, Marble 1.1 is a rapid ideation tool that works. Generating a believable environment in 60 seconds to show a client a mood and spatial feel — even as a rough 3D sketch — beats days of modeling. The dynamic scale expansion is exactly what cinematic environment work needs.”
