OpenAI-compatible LLM API for agents, apps, and SDKs.

Who OpenAI-Compatible LLM API from $6/mo is actually for

OpenAI-Compatible LLM API from $6/mo is best for developers and power users who want model access inside tools, agents, scripts, and apps, not just a closed consumer chatbot tab.

• Existing OpenAI SDK projects that need a cheaper backend.
• Tools that support a custom base URL and model name.
• Internal apps where migration cost needs to stay tiny.

Compatibility is the migration strategy

The fastest way to try another LLM backend is not rewriting your app. It is keeping the chat-completions shape and changing the base URL, API key, and model ID.

That is why Yolo-Auto focuses on the OpenAI-compatible /v1 surface. The API is familiar enough for existing clients while the infrastructure and pricing stay independent.

Try OpenAI-Compatible LLM API from $6/mo with a normal chat completion

The fastest test is a single request against the OpenAI-compatible endpoint. Use your real Yolo-Auto API key, then swap the model ID if the models page shows a newer default.

curl https://yolo-auto.com/v1/chat/completions \
  -H "Authorization: Bearer yolo_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen3.8-27b",
    "messages": [
      { "role": "user", "content": "Explain how to migrate an OpenAI-compatible client to a custom base URL without changing the app architecture." }
    ]
  }'

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.YOLO_AUTO_API_KEY,
  baseURL: "https://yolo-auto.com/v1"
});

const response = await client.chat.completions.create({
  model: "qwen3.8-27b",
  messages: [{ role: "user", content: "Explain how to migrate an OpenAI-compatible client to a custom base URL without changing the app architecture." }]
});

console.log(response.choices[0]?.message?.content);
