Build Reliable AI Apps

The world's fastest-growing AI companies rely on Helicone to route, debug, and analyze their applications.

1000+ AI teams use Helicone to build reliable products

One SDK for 100+ Models

Access every AI model through the OpenAI SDK. Switch providers by changing the model name—no code rewrites needed.

Plus 100+ more models from providers like: Mistral, Groq, Together AI, AWS Bedrock, Azure, and more

Code Example:

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://ai-gateway.helicone.ai",
  apiKey: process.env.HELICONE_API_KEY,
});

const response = await client.chat.completions.create({
  model: "gpt-4o-mini",  // Just change the model name!
  messages: [{ role: "user", content: "Hello!" }]
});

“The most impactful one-line change I've seen applied to our codebase.”
