What is Flux?

Flux is a new generation open source graph model launched by Black Forest Labs. It is available in three versions: Pro, Dev, and Schnell. It fully benchmarks Midjourney in terms of image quality, text rendering, and complex instruction understanding. Suitable for local deployment by developers, API calls by creative designers, and content creators with commercial needs.

Core Features

  • Three versions cover different scenarios: Pro (flagship), Dev (non-commercial open source), Schnell (extremely fast and lightweight)
  • It has strong text rendering capabilities and can accurately generate English text in images.
  • Supports local deployment and is compatible with mainstream workflows such as ComfyUI / Automatic1111
  • API is billed on a pay-as-you-go basis, allowing developers to integrate it into their own products.
  • FLUX.2 supports image editing and outputs up to 4MP resolution

Pricing Plans

The Schnell/Dev version is open source and free and can be deployed locally; the Pro version and API calls are pay-as-you-go, starting at about $0.07/piece (1MP), and there is no fixed monthly fee package.

Pros

  • The open source version is completely free to run locally with no usage restrictions
  • Image quality and detail comparable to Midjourney v6
  • Text rendering and complex prompt word understanding capabilities lead among similar open source models

Cons

  • Local deployment requires higher graphics cards and the entry barrier is not low.
  • The Pro version is not open source and can only be used through the API without a visual interface.
  • The official playground has limited functions, and ecological tools rely on third-party platforms

Developed by Black Forest Labs, founded by the former Stability AI core team, Flux quickly became the benchmark model in the field of open source image generation after its release in 2024. Its Schnell and Dev versions are open source under the Apache 2.0 / non-commercial license and can be run natively for free on platforms such as ComfyUI; the Pro version provides the highest quality commercial services through APIs.
