Swap from OpenAI to Kimi K2.7 Code in one line

Kimi K2.7 Code is Moonshot's frontier open-weight coding model — 256K context, native tool calling, vision input, and extended reasoning. Coding-tuned and agentic: built for the multi-step, tool-heavy edit loops that coding agents run, at a fraction of frontier-closed pricing.

AIgateway hosts it behind an OpenAI-compatible endpoint. So instead of installing a Moonshot SDK, integrating their auth flow, or porting your tool-call schema, you change one line in your existing OpenAI SDK code.

Set the base URL, swap the model

The only difference from a normal OpenAI client is the base_url and the model slug. Streaming, tool calling, vision, reasoning_content, JSON mode all work the same.

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aigateway.sh/v1",
    api_key="sk-aig-...",
)

stream = client.chat.completions.create(
    model="moonshot/kimi-k2.7-code",
    messages=[
        {"role": "system", "content": "You are a coding agent."},
        {"role": "user", "content": "Refactor this module to remove the dead branches."},
    ],
    tools=my_tools,
    stream=True,
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

TypeScript

Same swap on the JS side — change the baseURL, change the model slug.

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.aigateway.sh/v1",
  apiKey: process.env.AIGATEWAY_API_KEY,
});

const stream = await client.chat.completions.create({
  model: "moonshot/kimi-k2.7-code",
  messages: [{ role: "user", content: "hello" }],
  stream: true,
});

Use it in Cursor, Cline, or LangChain

Every OpenAI-compatible coding agent slots in by changing the base URL and the model ID. Cursor: Settings → Models → Override OpenAI Base URL to https://api.aigateway.sh/v1, add model moonshot/kimi-k2.7-code. Cline: API Provider → OpenAI Compatible, same base URL, Model ID moonshot/kimi-k2.7-code.

# LangChain
from langchain_openai import ChatOpenAI

llm = ChatOpenAI(
    model="moonshot/kimi-k2.7-code",
    base_url="https://api.aigateway.sh/v1",
    api_key="sk-aig-...",
)
print(llm.invoke("Hello!").content)
