Black Forest Labs — the German lab behind the FLUX image-model family, co-founded by Robin Rombach (original Stable Diffusion work) — released FLUX 3 Action as an open-weights 7B 'World Action Model' for robotics, claiming first place on NVIDIA's RoboLab-120 benchmark with a 42.92% overall success rate. The claim is that it beats the prior best open model by 6.1 points with 44% of the parameters (7B vs NVIDIA's 16B Cosmos3-Nano-Policy) and runs ~1.43x faster. It is the robotics offshoot of the FLUX 3 multimodal family announced July 2026, which jointly trains image/video/audio/action in one architecture; a partner variant (FLUX-mimic, with mimic robotics) is reportedly running on production tasks at Audi. Caveat for a stranger: the leaderboard numbers are vendor-reported via BFL's own announcement and press coverage echoes those claims — no independent benchmark results appear in the supplied material.
The radar already tracks this exact development in an open case: radar:flux-3-omnimodal-backbone predicts BFL demonstrating FLUX.3 unifying image, video, audio, and action in one flow-model backbone — this release is that prediction materializing, now with a concrete twist (open-weights 7B embodied policy beating NVIDIA's Cosmos3-Nano-Policy on RoboLab). That benchmark claim is vendor-reported with no independent replication in the supplied material, so it sits at the announcement end of Scott's Evidence Class Ladder; the notable residual fact for him is that a diffusion-image lab, not a robotics-native one, now ships the top open embodied policy — connecting his FLUX-based local tooling (gamepc, Replicate) to the radar's open-robotics thread.

The HN attachment is the same first-party BFL release post reaching a third platform (10 pts, 0 comments) — duplicate coverage of an artifact already echoed into the case, not a new fact or independent check. Meaning is unchanged: a vendor-reported RoboLab-120 claim still awaiting replication; measured rates (1.67 pts/h, 0 comments/h) say residual drift despite a high peer percentile, so low heat holds.

evidence attached: hn.story.49871965 — First-party Black Forest Labs release post for the already-open Flux 3 Action case — the primary artifact behind the RoboLab benchmark claims.

The one-day velocity spike decayed to zero by 09-26 with no new evidence; the leaderboard-link comment remains the only quasi-independent check and is unverified. Meaning is unchanged — a vendor-reported benchmark claim still awaiting replication — so the case cools to low heat and stays open for independent evals or hands-on results with the released weights.
