Six stats on Black Forest Labs' FLUX 3 Video: it reached general availability August 4, 2026, with BFL's own launch post naming no partner; four aggregators — Runway, Pika, Luma, and fal.ai — absorbed the model within about three weeks, none announced by BFL itself; the company's own About page calls it both 'the frontier AI research lab' and 'foundational infrastructure' in adjacent sentences; FLUX Upscale, its only new capability since launch, is priced $0.07 to $0.10 per megapixel-second and only processes FLUX 3 Video's own output; Artificial Analysis doesn't track FLUX 3 Video at all, leaving Design Arena's #4 ranking — down from BFL's own #2 debut — as the only public number; and Adobe Firefly highlights FLUX among its image partners while Runway, Kling and Luma head its video partner list, with Black Forest Labs absent.
