Overview
Stable Diffusion is an image-generation family of open-weight text-to-image models from Stability AI. It is run by Stability AI, a UK company founded in 2019, with large community contributions. You run it yourself locally: the weights are downloadable and are used through interfaces such as ComfyUI on consumer GPUs. No material change was found in this review. No pricing page or API price is recorded for it, because the developer platform pricing page returned only an empty shell when it was checked.

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
- Not recorded
The record does not state whether a public API exists.
Suggest a correction - Licence
- CreativeML Open RAIL-M
Mirrors the licence already recorded on the product record; not re-verified against the licence text by this migration.
Suggest a correction - Commercial use
- Not recorded
No licence terms recorded, so commercial use cannot be asserted.
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.
