What is Helicone?​

Helicone is an open source observability platform that proxies your OpenAI traffic and provides you key insights into your spend, latency and usage.

const model = new OpenAI(
  {},
  {
    basePath: "https://oai.hconeai.com/v1",
  }
);
const res = await model.call("What is a helicone?");

Now head over to helicone.ai to create your account, and add your OpenAI API key within our dashboard to view your logs.
