Setup

Uses an example ID from the current environment. It is not a recommendation unless the capability panel says so.

import OpenAI from "openai"

const client = new OpenAI({
  apiKey: process.env.TSUBASA_API_KEY,
  baseURL: "https://api.tsubasa.sh/v1",
})

const stream = await client.chat.completions.create({
  model: "tsubasa-medium",
  messages: [
    { role: "user", content: "Review this repository and propose a patch." },
  ],
  stream: true,
})

Current limitations

Only GET /v1/models and POST /v1/chat/completions are implemented.
Responses, Assistants, Files, Images, Audio, Embeddings, and Batch endpoints are not available.
Tool calls and structured outputs are not advertised by the current model definitions.

import OpenAI from "openai" const client = new OpenAI({ apiKey: process.env.TSUBASA_API_KEY, baseURL: "https://api.tsubasa.sh/v1", }) const stream = await client.chat.completions.create({ model: "tsubasa-medium", messages: [ { role: "user", content: "Review this repository and propose a patch." }, ], stream: true, })
