HiDream I1 Dev is a slimmed-down version of the HiDream I1 image model made public on April 7 2025. It still puts out high-quality images while running faster and using less power.
It runs 28 steps instead of 50 so it balances speed and sharpness.
It scores well on top open image tests like GenEval DPG-Bench and HPS v2.1 and sticks close to what you prompt it with.
It's open-source with 17 billion parameters under the MIT license so you can use it for business too.
Needs about 16 GB VRAM in FP8 or around 12 GB with smaller setups like GGUF which makes it work fine on most home GPUs.
Good fit for devs or researchers who want fast sharp results without the big load of the full model.
