What Kimi K3.1 Pro is
On 23 October 2026, Moonshot / Kimi introduced Kimi K3.1 Pro as the first model in the K3.1 series and its most capable 3T-class open-weight model to date, with a 1-million-token context window. The official tech blog says it improves coding, 3D creation, financial research, and other agentic work, and also lists a Highspeed variant.
Moonshot says Kimi K3.1 Pro and Kimi K3.1 Pro Highspeed are available on Kimi.ai, Kimi Work, Kimi Code, and the Kimi API (vendor ids kimi-k3.1-pro / kimi-k3.1-pro-highspeed). OpenRouter lists moonshotai/kimi-k3.1-pro. bnrouter does not invent a gateway model id or a price for this page.

Where developers can use it
Moonshot lists these official surfaces first. bnrouter is an optional OpenAI-compatible gateway in front of connected upstream accounts.
- Kimi.ai, Kimi Work, Kimi Code, and the Kimi API, as named in the 23 October 2026 tech blog
- OpenRouter listing moonshotai/kimi-k3.1-pro
- 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.
