Release date from the BFL release notes entry dated October 1, 2026 (the FLUX 3 family was announced 2026-07-23, but Image shipped later). The API id is the endpoint path POST https://api.bfl.ai/v1/flux-3-image. Max resolution is only given as a "4k" tier of about 16 MP, with no pixel dimensions, so maxResolution is null. The model page shows a 5456x3072 example. Not open weights: BFL offers FLUX 3 Image under a commercial weights licence through sales. Open weights are promised only for the "FLUX 3 Dev multimodal backbone", which is "coming soon". Not on the LMArena text-to-image table as of 2026-10-14. Text rendering is not claimed as a feature, so it is not listed, though the examples contain typography.
