FLUX.2: specs, access and what it's best at
Updated July 22, 2026
ReleasedFLUX.2 is Black Forest Labs' second-generation image family. The Pro tier beats Midjourney V7 on photorealism in blind tests, supports multi-reference on up to 10 images, and edits at up to 4 megapixels — while open-weight tiers make it the state-of-the-art choice for self-hosting.
The open-weight photorealism leader — four tiers, self-hostable.

What it is
FLUX.2 ships in four tiers: Pro (production API), Flex (developer variant), Dev (32B open weights on Hugging Face) and Klein (Apache-2.0, sub-second on consumer GPUs). Together they consolidated the open-weight frontier for image generation and editing.
What it's best at
Cinematic photorealism and production control — especially if you want to self-host. It preserves character identity and style across edits, which makes it a workhorse for repeatable business assets and pipelines that can't depend on a hosted-only API.

Frequently asked questions
- Is FLUX.2 open weights?
- Partly. FLUX.2 [dev] ships 32B open weights on Hugging Face and FLUX.2 [klein] is Apache-2.0 and runs sub-second on consumer GPUs. Pro and Flex are hosted API tiers.
- Which FLUX.2 tier should I use?
- Pro for top-quality hosted production, Flex for a tunable developer API, Dev for self-hosted state-of-the-art open weights, and Klein for fast local generation on a single GPU.
- FLUX.2 vs Nano Banana 2?
- FLUX.2 is the open-weight photorealism and self-hosting choice; Nano Banana 2 is the faster, cheaper hosted default with web-search grounding. Pick by whether self-hosting and photorealism, or speed and convenience, matter more.
