The model is built for layout and long text, so posters, menus, signs and infographics come out with accurate English and Chinese lettering. Always returns a single PNG. Image editing is not available for this model; requests with `image_list` are rejected. **Pricing** — flat per image by resolution tier: | image_size | Tokens | USD | |---|---|---| | 1K (about 1 MP, default) | 1 | $0.02 | | 2K (about 4 MP) | 4 | $0.08 | **Text in the image** — put the exact words you want rendered in quotes, for example `a sign that reads "OPEN 24 HOURS"`. Chinese and English can be mixed in one prompt. Long prompts (up to 4000 characters) are fine and help with dense layouts. Text you do not specify may come out as filler. **Timing** — about 15 to 20 seconds of processing for 1K, and about 1 to 2 minutes for 2K, plus queue time. ## OpenAPI ````yaml api-reference/image-api/openapi-moss-image.json POST /api/v1/images/generations openapi: 3.1.0 info: title: GoEnhance API - MOSS-Image description: MOSS-Image version: 1.0.0 servers: - url: https://api.goenhance.ai security: [] paths: /api/v1/images/generations: post: tags: - ImageAPI summary: MOSS-Image description: >- MOSS-Image text to image.

When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail.
