Model Card

HiDream I1 Fast is the lowest-latency variant of HiDream AI's 17-billion-parameter text-to-image model family, completing generation in as few as 14-16 diffusion steps.

Like the Dev variant, it is distillation-trained and does not require negative prompts. It is the best-fit variant for latency-sensitive API integrations, delivering strong image quality for its step count.

I1 Fast is the right choice for real-time generation features, high-throughput batch pipelines, or user-facing products where responsiveness is the primary constraint. Maximum fidelity is reserved for the Full variant.
