MOSS Image API

What MOSS Image is

OpenMOSS describes MOSS Image as a text-to-image family with native layout control. Besides natural-language prompts, the project page says objects, rendered text, and their positions can be specified in a structured JSON prompt, with emphasis on Chinese and English text rendering.

The official page dated 16 October 2026 introduces MOSS-Image-Base with public code and weights, plus a curated-data SFT checkpoint. fal lists a hosted fal-ai/moss-image text-to-image endpoint. bnrouter does not invent a gateway model id or a price for this page.

Where developers can use it

OpenMOSS lists these official surfaces first. bnrouter is an optional OpenAI-compatible gateway in front of connected upstream accounts.

Hosted fal-ai/moss-image endpoint listed by fal
bnrouter, if the operator has connected an upstream that serves this model. The plaza may still show coming soon — confirm the id in the console or GET /v1/models.

How to call it through bnrouter

bnrouter is an OpenAI-compatible AI API gateway. Create an API key in the console, then send requests to the gateway base URL. Chat completions may not be the right request shape for image or video generation — see the Image & video API docs for the images format this site already documents. This repository does not yet record a gateway model id — copy the id shown in the console (or from GET /v1/models) into the model field. The plaza listing may still show coming soon.

curl

curl https://www.bnrouter.com/v1/chat/completions \
  -H "Authorization: Bearer $YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "YOUR_MODEL_ID",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://www.bnrouter.com/v1",
)

resp = client.chat.completions.create(
    model="YOUR_MODEL_ID",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)

Replace YOUR_API_KEY and YOUR_MODEL_ID with values from the console. Do not assume a model id that is not listed there.
