FLUX 3 is the multimodal model family Black Forest Labs announced on July 23, 2026. One architecture handles images, video with native audio and, through partners, robot actions.
The rollout is split into separate products: FLUX 3 Video, FLUX 3 Image, the smaller FLUX 3 Image Klein, FLUX 3 Action, and FLUX 3 Dev open weights, which BFL says are coming soon. Nano AI runs FLUX 3, FLUX 3 Image Klein and FLUX 3 Video through a hosted API.

FAQ
FLUX 3 questions
Can I use FLUX 3 online?
Yes. FLUX 3 text-to-image and image editing run in the workspace on this page. You need a Nano AI account and credits; there is nothing to install.
Who makes FLUX 3?
Black Forest Labs, the team behind FLUX.1 and FLUX.2. Nano AI is an independent platform that runs FLUX 3 through an API provider and is not affiliated with Black Forest Labs.
How much does FLUX 3 cost on Nano AI?
One image costs 10 credits at 1K, 24 at 2K and 130 at 4K. FLUX 3 Image Klein starts at 2 credits, and FLUX 3 Video is billed per second of output.
Can FLUX 3 edit my own photos?
Yes. Upload 1 to 10 reference images and describe the change. FLUX 3 uses them for edits, product placement, style transfer or keeping a character consistent.
Can FLUX 3 put text inside images?
It handles short headlines and labels well, as the poster sample shows. Put the exact words in quotes, keep them short and check the spelling before you publish.
What is the difference between FLUX 3 and FLUX 3 Image Klein?
Klein is the smaller, faster model: up to 2K and 3 reference images, from 2 credits. FLUX 3 costs more but reaches 4K, takes 10 references and keeps more detail.
Can FLUX 3 make videos?
Yes, through FLUX 3 Video: text-to-video, image-to-video, start-and-end-frame transitions and clip extension, 5 to 20 seconds at 720p or 1080p, with optional audio.
Are FLUX 3 open weights available?
Not yet. Black Forest Labs says open weights for the FLUX 3 Dev backbone are coming soon. Until then FLUX 3 runs through hosted APIs like the one this workspace uses.
