What Muse Image is best at
Instruction fidelity
Muse renders what you asked for — counts, placement, wording — rather than a plausible approximation of it.
Fine detail that holds up
Accurate rendering where most models smear: text in the image, plots and charts, QR codes.
Localized edits
Edit mode changes the region you name and leaves the rest of the image alone — no collateral drift.
Compose from 10 references
Up to 10 reference images in one edit request — products, people, backgrounds, and layouts combined in a single pass.

How to use Muse Image on Genfire
- 1
Describe it
Write a prompt, and pick Muse Image in the model selector.
- 2
Generate & compare
Render the image, iterate on the prompt, or run the same brief on a sibling model to compare — all from one credit balance.
- 3
Finish & publish
Send the result into Genfire's editor, upscaler, and audio tools, then export platform-ready output.
Does what the prompt says
The habitual failure of image models is not ugliness; it is approximation. They catch the gist of a prompt and improvise the specifics, which is fine for a mood board and useless for anything with hard requirements. Muse Image is Meta's answer to that failure. Its design goal is fidelity — follow the instruction as written, and render fine detail accurately rather than decoratively. The examples Meta leads with are telling: text, plots, and QR codes are all cases where "roughly right" is simply wrong. A chart with the wrong number of bars is not a chart, and a QR code with invented modules is a decoration. For product mockups that need a real UI on screen, slides that need a legible graph, flyers that need a code in the corner, and packaging that needs the copy you wrote, that fidelity is the whole point.
The edit mode extends the same discipline to existing images. Ask Muse to change one element and it changes that element — the mug turns black, the laptop, notebook, and light stay put. It also composes: a single edit request can draw on up to 10 reference images, which is enough to bring a product, a setting, a lighting reference, a model, and a layout into one frame without stitching several generations together. Two controls deserve a note. Muse offers nine aspect ratios spanning ultrawide 21:9 through square to tall 9:21, but the ratio is optional; leave it out and Muse sizes the output from the prompt itself, so "a tall phone screenshot" comes back portrait without being told. And there is no resolution or quality control — output size is fixed by the model — so when a final needs to be larger, the route is Genfire's image upscaler downstream rather than a setting on the model.
On Genfire, Muse Image is one dropdown from the models it pairs well with. GPT Image 2.5 is the photoreal choice with up to 16 references and masked inpainting; Nano Banana is the general-purpose editor; Qwen Image 3 handles Chinese and English text together; Recraft V4 covers vector and design-system output. Muse is the one to pick when the brief has exact requirements — copy, data, codes, counts — and the cost of an approximation is a redo. It runs in the browser studio, on the REST API as image.muse_image, through the MCP server at mcp.genfire.ai, and from the @genfire/cli, with no Meta account required. Genfire is pay-as-you-go: credit packs start at $19, purchased credits last 12 months, optional monthly plans start at $29, and every purchase includes a commercial license.

Muse Image — frequently asked questions
What is Muse Image?
Muse Image is Meta's image generation and editing model, built for faithful instruction-following and accurate fine detail such as text, plots, and QR codes. Its edit mode makes precise localized changes and composes from up to 10 reference images.
What is Muse Image best at?
Briefs with exact requirements: readable text inside the image, charts and plots that show the right data, QR codes, and edits that must change one thing without disturbing the rest.
Can Muse Image edit existing images?
Yes. Edit mode applies precise, localized changes to the region you describe and can compose a new image from up to 10 reference images in a single request.
How many reference images does Muse Image accept?
Up to 10 per edit request on Genfire, with up to four output images per request.
Which aspect ratios does Muse Image support?
Nine: 21:9, 16:9, 4:3, 3:2, 1:1, 2:3, 3:4, 9:16, and 9:21. The aspect ratio is optional — omit it and Muse sizes the output from the prompt.
Can I set the resolution or quality on Muse Image?
No. Muse Image has no resolution or quality control; output size is fixed by the model. For larger finals, run the result through Genfire's image upscaler.
How do I use Muse Image and what does it cost?
Generate in Genfire's browser studio with no Meta account, or call it on the REST API as image.muse_image, through the MCP server, or from the CLI. Genfire is pay-as-you-go: credit packs start at $19, purchased credits last 12 months, and every purchase includes a commercial license.
