FLUX.2 (Flux 2)

Black Forest Labs released FLUX.2 on November 25, 2025 as a family: pro and flex through the API, dev as 32-billion-parameter open weights, klein as the small distilled version and max at the top. One model does text-to-image and editing with up to ten reference images. Here is what each variant is for, what the license allows, and what to use in LazyKiwi.

Using it

How to use FLUX.2

LazyKiwi does not run FLUX.2. These are the routes Black Forest Labs and its partners offer.

1

Hosted: BFL Playground or a partner

FLUX.2 [pro] and [flex] run in the BFL Playground and API; fal, Replicate, Runware, Together, Cloudflare and DeepInfra host dev and pro endpoints with per-image billing.

2

Local: FLUX.2 [dev] or [klein]

Download the weights from Hugging Face and run them in ComfyUI or diffusers. The card suggests an RTX 4090 or 5090 with a 4-bit quantized model; output is for non-commercial use under the dev license.

Need images now, no setup?

LazyKiwi's image generator runs Z-Image, Qwen Image, Nano Banana and GPT Image 2 in the browser with free credits on sign-up, up to 4K.

What it is

What FLUX.2 is built for

FLUX.2 replaced the FLUX.1 line with one architecture for generation and editing: a 24B Mistral-3 vision-language model paired with a rectified flow transformer and a redesigned VAE. Black Forest Labs sells it on prompt adherence, text rendering and consistent characters across references.

Multi-reference

Up to ten reference images at once

FLUX.2 takes up to 10 reference images in one request and keeps the character, product or style consistent across them, which turns a generator into an editor for product shots and brand sets.

  • Up to 10 references per request
  • Editing and generation in one model
  • Output up to 4MP, any aspect ratio

Variants

pro, flex, dev, klein, max

pro is the production model behind the API; flex exposes steps and guidance for typography and fine detail; dev is the 32B open-weight model on Hugging Face; klein is a size-distilled version for fast iteration, later shipped on-device with ASUS ProArt laptops (June 4, 2026); max is the top-quality tier with grounded generation.

  • pro and flex: BFL API and partners
  • dev: open weights, 32B parameters
  • klein: distilled, Apache 2.0 per the launch post

License

Open weights, but dev is non-commercial

FLUX.2 [dev] ships under the FLUX Non-Commercial License on Hugging Face; commercial output goes through the API models (pro, flex, max) or a separate agreement. The model card points to an RTX 4090 or 5090 for local use with a 4-bit quantized build.

  • dev: FLUX Non-Commercial License
  • Commercial use: pro / flex / max via API
  • Local: RTX 4090 class GPU, 4-bit quantized

What came next

FLUX 3 followed in July 2026

Black Forest Labs announced FLUX 3 on July 23, 2026, then FLUX 3 Video (August 4, 2026) and FLUX 3 Action (September 23, 2026). FLUX.2 remains the open-weight image family most hosts run, and the one people search for by name.

  • FLUX 3 announced July 23, 2026
  • FLUX 3 Video: August 4, 2026
  • FLUX.2 still widely hosted

Up to ten in a single request, keeping the character, product or style consistent across them.

What hardware does FLUX.2 [dev] need?

The model card points to an RTX 4090 or RTX 5090 running a 4-bit quantized model with a remote text encoder. Smaller cards need klein or a hosted endpoint.

Is FLUX 2 the same as FLUX.2?
