HiDream O1 is HiDream's open image model for text-to-image and reference-image edits. It is built for instruction-following changes from a source still rather than generating from a blank canvas alone.

Use it when you already have a still and need a directed edit, or when you want an open-weight image model on the same credit balance as the rest of the studio.

Why HiDream O1 is good

Reference-image edits

O1 is built to take a source still and follow an instruction: restyle, recast, relight, or change an object without starting from a blank canvas.

Text to image

The same route also generates from a prompt alone, so you can sketch a new frame, then edit it in the next take with a reference.

Open model, studio-priced

HiDream released O1 as an open model. On Elyum it is 2.4 credits ($0.02) per kept render, about 20% under comparable studio pricing.

Five aspect ratios

Pick from five aspect ratios in the image studio so the take matches the frame you need before you keep it.

Pay only for keeps

Every render is a free preview. Credits move only when you KEEP a take. Kill the rest and the charge is refunded in full.
