import * as braintrust from "braintrust";

async function main() {
  const experiment = await braintrust.init("NodeTest", {
    apiKey: "YOUR_API_KEY",
  });
  experiment.log({
    input: { test: 1 },
    output: "foo",
    expected: "bar",
    scores: {
      n: 0.5,
    },
    metadata: {
      id: 1,
    },
  });
  console.log(await experiment.summarize());
}

main().catch(console.error);
