The Image Studio is the visual half of the Unified Post Editor. It is where you generate, iterate on and save the images for a post, without leaving the post.

​
Opening the studio

Select Generate on the Attachments card under the post body. The studio opens in place over the editor, headed Image Studio. Close it with the ✕ and you are back in the post with your copy untouched.
Everything to do with generating and re-prompting happens inside the studio. The Attachments card outside it only attaches and removes: hover an attached visual for the ✕ that takes it off the post. To change a visual, open the studio again with Generate.

​
Generating an image

The prompt box reads “Guide the image (optional) — your post copy & brand are used as the base”. You can leave it empty: Rheos works from the post you have written and your brand identity. Type into it to steer the result. Around the prompt sit the controls:
  • The aspect-ratio picker, headed Select Aspect Ratio — it offers only the ratios that work for every platform you have selected.
  • Model — see below.
  • Web search (the globe) — grounds the generation in a live search. Only offered on the two Nano Banana models, and it costs a little more per image.
  • Deeper thinking (the brain) — asks the model to think harder before it draws. The tooltip warns it is slower. Nano Banana 2 only.
  • Generation settings (the cog) — Batch (1 to 4 images per run), the cost of the run, and a Parameters panel listing the model, size, batch and resolution the run will use.
The generate button carries the run’s cost as a badge, so you can see what a change to the settings does before you select it.

​
Logos and reference assets

Above the prompt is a row with two halves:
  • Logos — your brand’s uploaded logos. Select one to include it in the generation.
  • Reference Assets — images or documents for the model to work from. Add them from your library, paste them in, or let Rheos suggest matches from your library once your prompt is ten characters or longer. You can carry up to ten references and logos combined.
Upload a clean transparent-background PNG of your logo for the best results.

​
Picking a model

Pick a specific model and Rheos calls it directly. On Auto it tries Google AI Studio first and falls back to Fal.ai only when Google is rate-limited or unavailable; any other failure is reported rather than retried elsewhere.

​
Working with a generated image

Hover a result and the action bar gives you:
  • Add to post — attaches it to the draft.
  • Regenerate — re-runs the same prompt and settings for a fresh result.
  • Edit (iterate on this image) — seeds a new run from this image; the prompt box switches to “Describe the change…”.
  • Save to library — the heart. Keeps it in your Library for reuse in later posts.
  • Download, Open full size and Delete.
Select several at once and a bar appears at the top with Add to post, Save to library and Delete across the whole selection.

​
What a generation costs

The studio shows the cost of a run before you start it — on the cog’s Generation settings panel, and as a badge on the generate button. Four things move it:
  • How many images. Cost is per image, so a batch of four costs four times a single one. A regenerate or an Edit is a fresh generation, charged the same way.
  • Which model. GPT Image 2 on low quality is the cheapest single image; Nano Banana Pro, and GPT Image 2 on high, are the most expensive. Auto sits at the cheaper end.
  • Resolution and quality. Stepping Nano Banana 2 from 1K to 2K costs more; Nano Banana Pro charges the same at either. GPT Image 2 costs more each time you step the quality up from low to medium to high.
  • Web search, which adds a little on top of a Nano Banana run.
Attaching an image you already have, and uploading your own to the Library, cost nothing.
4K is not available on customer accounts yet — the 4K resolution option is greyed out.
How much generating you can do is governed by your plan’s fair-use limits — see plans.
