From our tests
Strengths and limits
Good at
- The cheapest good-looking images in the generator: Dev and Klein, on the free plan.
- Natural light and skin in photo prompts; handles fantasy and dark art well.
- Reference-based editing: a sketch or 3D blockout becomes a finished image with “same pose”.
- Nine versions from quick drafts to Max, so you can draft cheap and finish high.
Limits
- In our test, Flux 2 Dev's edit endpoint ignored the strength setting — use Z Image Base when you need that control.
- Up to 3 references on Dev (4 on Flash and Turbo) — fewer than Seedream (10) or GPT Image 2 (16).
- Less polished than Seedream 5.0 Pro on close-up portraits.

FAQ
Flux 2 questions
What is Flux 2?
Flux 2 (FLUX.2) is Black Forest Labs' family of image generation and editing models, announced on 25 November 2025. It includes Dev, Klein, Pro, Flex and Max versions, and every version supports text to image plus single- and multi-reference editing. Dev is a 32-billion-parameter open-weights model; the compact Klein models followed on 15 January 2026.
Link to this answerIs Flux 2 free?
Yes, to start. Flux 2 Dev, Klein, Flash and Turbo are on Kenerate's free plan, and every new account gets free starter credits on sign-up to try them. Pro, Flex, Max and the Klein Base versions need a one-time credit pack, with no subscription required, and credits never expire. Downloads have no watermark.
Link to this answerWhat's the difference between Flux 2 Dev and Klein?
Dev is the 32-billion-parameter open model under a non-commercial licence and the quality sweet spot; Klein is a smaller family built for speed, in 4B (Apache 2.0) and 9B (non-commercial) sizes. In our same-prompt test, Dev gave the richest light and Klein was fastest. On Kenerate both are on the free plan and take up to 3 references.
Link to this answerCan Flux 2 edit images?
Yes. Every Flux 2 version supports single- and multi-reference editing. On Kenerate, Flux 2 Dev takes up to 3 reference images, and Flash and Turbo take up to 4. Upload a sketch or 3D blockout and say what to keep, such as “same pose”. In our test Dev's edit ignored the strength setting, so use Z Image Base when you need that control.
Link to this answerIs there a Flux 3?
Yes, for video. Black Forest Labs announced the FLUX 3 family on 23 July 2026, and FLUX 3 Video — 5–20 second clips with sound — runs on Kenerate now. For images, FLUX.2 (announced November 2025) is still the family you can use: Kenerate runs nine FLUX.2 versions, from Dev and Klein on the free plan up to Flux 2 Max for the highest fidelity, and lists each one on this page.
Link to this answerCan I run Flux 2 locally?
Some versions, yes. Flux 2 Dev is a 32-billion-parameter open-weights model under a non-commercial licence, and Flux 2 Klein comes as open 4B (Apache 2.0) and 9B (non-commercial) models, so you can download and run them yourself. On Kenerate all nine versions run in the browser with no install, with Dev and Klein on the free plan.

Background, how to prompt it, and when to pick something else.
The FLUX.2 family
Black Forest Labs announced FLUX.2 in November 2025 with Pro, Flex, Dev and Klein models, and released the compact Klein models in January 2026 [2]. Every version supports text to image plus single- and multi-reference editing [1].
- Dev — 32B open weights, the quality/price sweet spot.
- Klein 4B / 9B — small and fast; Base versions are undistilled for fine-tuning.
- Pro, Flex, Max — hosted versions for higher fidelity and typography.
Drafting cheap, finishing high
Because Dev and Klein sit on the free plan, a common workflow is to explore ideas there, keep the seed and prompt you like, and re-run the final on Flux 2 Pro, Max or Seedream 5.0 Pro.
