OpenAI Format Converter

Overview

The OpenAI Format Converter allows you to call Gemini and Anthropic models using the OpenAI SDK and API format. This is useful when you have existing code using the OpenAI SDK but want to access other providers’ models.

Configuration

SDK Configuration

Set your base URL to:

https://api.pipellm.ai/openai

The SDK automatically appends /chat/completions, so you only need to set the base URL to /openai/v1.

cURL / Direct API

For direct API calls, use the full endpoint:

https://api.pipellm.ai/openai/v1/chat/completions

Usage Examples

Python SDK
TypeScript SDK
cURL

from openai import OpenAI

client = OpenAI(
    api_key="your-pipellm-api-key",
    base_url="https://api.pipellm.ai/openai/v1"
)

response = client.chat.completions.create(
    model="gemini-2.0-flash",  # or "claude-sonnet-4-20250514"
    messages=[
        {"role": "user", "content": "Hello, how are you?"}
    ]
)

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

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "your-pipellm-api-key",
  baseURL: "https://api.pipellm.ai/openai/v1",
});

const response = await client.chat.completions.create({
  model: "gemini-2.0-flash", // or 'claude-sonnet-4-20250514'
  messages: [{ role: "user", content: "Hello, how are you?" }],
});

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

  -H "Content-Type: application/json" \
