Where developers can use it
MiniMax lists these official surfaces first. bnrouter is an optional OpenAI-compatible gateway in front of connected upstream accounts.
- MiniMax API, M Plan, and MiniMax Code, as named in the 19 October 2026 post
- OpenRouter listing minimax/minimax-m3.1-flash
- 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 accepts the OpenAI chat completions protocol. Create an API key in the console, then send requests to the gateway base URL. 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 https://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!"}]
}'from openai import OpenAI
client = OpenAI(
api_key="YOUR_API_KEY",
base_url="https://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.
