How do I pick Flash, Max or Heavy in JavaScript?

Pick the model id, or send the family id with an effort.

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.gateway.clatterlabs.xyz/v1",
  apiKey: process.env.CLATTER_API_KEY,
  defaultHeaders: { "X-Clatter-Account": process.env.CLATTER_ACCOUNT_ID },
});

await client.chat.completions.create({ model: "supercosmos-heavy", messages });
await client.chat.completions.create({ model: "supercosmos", effort: "max", messages });           // family + effort
await client.chat.completions.create({ model: "supercosmos", reasoning_effort: "low", messages });  // low=Flash, medium=Max, high=Heavy

No effort with the family id means Flash. An unknown value answers 400 invalid_effort.

Every JavaScript example uses the same client (base URL, key and the X-Clatter-Account header); see Set up the JavaScript SDK. Full parameter list: Create a chat completion.
