Evidence claims:
- [sourced_fact] README: code and HiDream-I1 models are both under the MIT License; Full 50 steps, Dev 28 steps, Fast 16 steps; Dev/Fast use guidance 0.0, Full 5.0 in the Diffusers example. · source: https://github.com/HiDream-ai/HiDream-I1
- [sourced_fact] Automatic text-encoder download requires accepting the Meta Llama-3.1-8B-Instruct license on Hugging Face; Flash Attention and CUDA 12.4 suggested. · source: https://github.com/HiDream-ai/HiDream-I1
- [sourced_fact] Latest dated entry on the page is 16 July 2025, announcing open-sourcing of the editing model HiDream-E1-1. · source: https://github.com/HiDream-ai/HiDream-I1
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
