Most Chat Completions applications only need a new base URL, API key, and model name. The rest of the request and response handling stays the same.

Before you begin

You need a W&B API key, a project with routing applied, and the project’s W&B entity.

Python
JavaScript
cURL

import os

from openai import OpenAI

client = OpenAI(
    base_url="https://proxy.training.wandb.ai/v1",
    api_key=os.environ["WANDB_API_KEY"],
)

response = client.chat.completions.create(
    model="ticket-classifier",
    messages=[
        {"role": "user", "content": "My package arrived damaged. What should I do?"}
    ],
    extra_body={
        "metadata": {
            "wandb.entity": "your-team",
            "wandb.thread_id": "customer-4827",
        }
    },
)

print(response.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://proxy.training.wandb.ai/v1",
  apiKey: process.env.WANDB_API_KEY,
});

const response = await client.chat.completions.create({
  model: "ticket-classifier",
  messages: [
    { role: "user", content: "My package arrived damaged. What should I do?" },
  ],
  metadata: {
    "wandb.entity": "your-team",
    "wandb.thread_id": "customer-4827",
  },
});

console.log(response.choices[0].message.content);

curl https://proxy.training.wandb.ai/v1/chat/completions \
  -H "Authorization: Bearer $WANDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "ticket-classifier",
    "messages": [
      {"role": "user", "content": "My package arrived damaged. What should I do?"}
    ],
    "metadata": {
      "wandb.entity": "your-team",
      "wandb.thread_id": "customer-4827"
    }
  }'

Omit wandb.entity only when the project belongs to the API key’s default entity.

Verify the integration

Return to the project overview after sending a request. Confirm that:

the request count increased;
the expected model served the request;
the saved input and answer look correct.

If the proxy says the project does not exist in a personal entity, add the team name in metadata["wandb.entity"].

Preserve conversation identity

Use the same wandb.thread_id for every request in one conversation. This keeps a conversation on the same model during a gradual rollout and keeps related examples together when preparing data.
