Overview
FLUX is an image-generation product from Black Forest Labs: a family of text-to-image and multimodal generative models, with open-weight downloads and a hosted API. Black Forest Labs is a German company founded in 2024 by researchers behind Stable Diffusion. Open-weight versions can be run and fine-tuned on your own hardware, so the product is used locally or self-hosted, while the strongest models are reached through the hosted API and its per-image pricing. No material change was found in this review. The clearest limitation is licensing: the Apache-2.0 terms cover the code repository only, FLUX.1-dev is non-commercial, and no documentation URL is recorded.

Derived from record tag matching /^open-weights$/.
Suggest a correction - Runs on
- Not recorded
No platform support is stated in the record.
Suggest a correction - Where it runs
- Local machine
Open-weight models are run by the user, not served by the vendor.
Suggest a correction - Works offline
- Partly
Local execution implies the model can run without a network once downloaded, but the vendor does not state this in the record.
Suggest a correction - Official service region
- Global
Mirrors the availability field already on the record ("global").
Suggest a correction - Public API
- Yes
The pricing page documents an API next to the open-weights download.
Suggest a correction - Licence
- Apache-2.0 (schnell) / FLUX.1-dev Non-Commercial
Mirrors the licence already recorded on the product record; not re-verified against the licence text by this migration.
Suggest a correction - Commercial use
- Permitted
Recorded licence allows commercial use (copyleft obligations may still apply).
Suggest a correction - Interface languages
- Not recorded
No vendor page read in this pass states the product's own interface languages; the key exists so the field can be answered later rather than left absent.
