A Volaris Labs product

Production AI inference, one endpoint away.

Kymo gives you a fast, OpenAI-compatible chat completions API plus a full playground for prompting, streaming, vision and structured output.

typescript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.KYMO_API_KEY,
  baseURL: "https://kymo.volarishq.uk/api/public/v1",
});

const res = await client.chat.completions.create({
  model: "kymo-large",
  messages: [{ role: "user", content: "Explain quantum tunneling briefly." }],
  stream: true,
});

for await (const chunk of res) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}
