What it is
FLUX 3 is Black Forest Labs' first video model, announced on 23 July 2026 and still labelled a preview in BFL's documentation. It is one model trained jointly on images, video, audio and robot actions. FLUX 3 Video makes clips of 5 to 20 seconds at 24 fps, from HD up to 3840 × 2176 for 16:9, with optional generated dialogue, effects and ambience at no extra charge.
Requests go to one endpoint in three modes: text to video, image to video (one to ten keyframes) and continuation of an existing clip (up to 15 seconds). A Draft mode renders a fast HD preview that can later be re-rendered at full quality with the same seed. Prompt-based editing sits in a separate FLUX Video Edit [fast] tool, and a faster FLUX 3 Max variant is offered on fal.
FLUX 3 Image (generation and editing with up to ten reference images) followed in October 2026, alongside FLUX 3 Image Klein, a 5.6-billion-parameter image model with open weights under BFL's FLUX Kommunity licence, and FLUX 3 Action, a 7B open-weights model for robots. The video model itself has no open weights; a FLUX 3 Dev backbone is still listed as coming soon.
Our review
FLUX 3 is a credible first video model rather than a leader. On Artificial Analysis's text-to-video board with audio it sits eighth at 1145 Elo, behind Wan 3.0 (1175), MiniMax H3 and Seedance 2.5, and behind BFL's own FLUX 3 Max (1155), which the board prices at $2.55 a minute against $17.40 for standard FLUX 3 at 1080p. The image model is mid-table too: FLUX 3 Image is thirteenth on the text-to-image board at 1117.
The case for it is control. Up to ten keyframes can be pinned to exact timestamps, a clip can be continued from its own frames, and Draft mode lets a director audition a 20-second shot for $1.20 before paying $5.80 to finish it in FHD or $16 in 4K. Because the enhance step reproduces the same take, the draft rate rather than the 4K rate decides what exploration costs.
Production limits are tight. BFL's quickstart says generations take several minutes and an organisation may run five at once, returning HTTP 429 beyond that, so a team rendering 100 shots an afternoon will queue. Result URLs expire about two hours after a job finishes, and BFL says it may delete video outputs after that window, so storage is the integrator's job from day one.
Buyers should read the API terms before sending client footage. They grant BFL a perpetual licence to use inputs and outputs to train its models, with no opt-out in the published terms; BFL lists ISO 27001:2022 and SOC 2 Type II, but anything different has to be negotiated through an enterprise order form. For agencies already licensing FLUX image weights the single vendor is convenient, though the open Klein image model is the part of the release that carries the fewest strings.
Where it earns its place
A six-person creative agency producing social ads
Explore several takes of each shot before committing budget
Render five 15-second drafts per shot at $0.90 each, then enhance the chosen one in FHD for $4.35. Two hundred finished shots a month with that ratio costs about $1,770, and the five-job concurrency cap sets the pace.
A backend engineer adding video to a marketing SaaS
Generate short product clips from customer photos
Send photos as keyframes to the image-to-video mode, poll or use a webhook, and copy results to your own storage within two hours. Customer images become BFL training data under the standard API terms, which needs to appear in your own privacy notice.
A post-production house delivering to broadcast
Extend or alter existing footage at 4K
Continuation mode extends a clip by up to 15 seconds at $0.95 a second in 4K, and Video Edit [fast] handles prompt-based changes. Heavy use goes through enterprise pricing, which BFL does not publish.
Before you commit
- Setup
- Create an account, buy credits (1 credit = $0.01) and call /v1/flux-3-video with an x-key header; the job is asynchronous, so a first clip means submit, poll and download, several minutes per generation.
- Integrations
- REST API with global, EU (api.eu.bfl.ai) and US (api.us.bfl.ai) endpoints, webhooks, a hosted MCP server with OAuth, and partner access on fal.
- Data and privacy
- The FLUX API Service Terms let BFL use inputs and outputs to train its models; no opt-out is published. Output URLs expire after about two hours. BFL lists ISO 27001:2022 and SOC 2 Type II; data residency is chosen by regional endpoint.
- Cost at scale
- A 20-second clip costs $1.20 as a draft, $3.40 in HD, $5.80 in FHD and $16 in 4K. Artificial Analysis puts a minute of 1080p at $17.40, against $2.55 for FLUX 3 Max at 720p. Volume discounts are enterprise-only and unpublished.
- Limits
- Clips run 5 to 20 seconds (continuation up to 15), drafts are HD only, five concurrent generations per organisation, and the model is still marked preview, so behaviour and prices may change.
What's good
- Draft previews at $0.06/s, re-rendered with the same seed
- Up to ten timed keyframes and clip continuation
- 4K at 24 fps with audio at no extra charge
- EU and US regional API endpoints
What's not
- Eighth on Artificial Analysis's video board, behind its own Max variant
- Five concurrent generations per organisation
- API terms allow BFL to train on inputs and outputs
- Still a preview; video weights not released
Best for
Studios and agencies that iterate on shots in drafts and need 4K delivery from a vendor they already use for images.
Alternatives
FLUX 3: common questions
- Is FLUX 3 worth it?
- A capable preview with real production controls, priced and rate-limited like a model still finding its feet. We rate it 4.2 out of 5.
- How much does FLUX 3 cost?
- Per second of video: Draft HD $0.06; HD $0.17, FHD $0.29, QHD $0.40, 4K $0.80 (continuation $0.12 to $0.95); audio included. FLUX 3 Image about $0.048 per image.
- What are the downsides of FLUX 3?
- Eighth on Artificial Analysis's video board, behind its own Max variant; five concurrent generations per organisation; aPI terms allow BFL to train on inputs and outputs; still a preview; video weights not released.
- Who is FLUX 3 best for?
- Studios and agencies that iterate on shots in drafts and need 4K delivery from a vendor they already use for images.
- How much does FLUX 3 cost for a team or in production?
- A 20-second clip costs $1.20 as a draft, $3.40 in HD, $5.80 in FHD and $16 in 4K. Artificial Analysis puts a minute of 1080p at $17.40, against $2.55 for FLUX 3 Max at 720p. Volume discounts are enterprise-only and unpublished.
- Is FLUX 3 safe for company data?
- The FLUX API Service Terms let BFL use inputs and outputs to train its models; no opt-out is published. Output URLs expire after about two hours. BFL lists ISO 27001:2022 and SOC 2 Type II; data residency is chosen by regional endpoint.
- What are the best FLUX 3 alternatives?
- The closest alternatives we have reviewed are Wan 3.0, Seedance 2.5, Gemini Omni Flash 1.1 and MiniMax H3 (Hailuo 3.0).
