Python

from openai import OpenAI

# Before:
# client = OpenAI(api_key="sk-...")

# After (only 2 lines change):
client = OpenAI(
    base_url="https://api.brainiall.com/v1",  # ← changed
    api_key="brnl-..."  # ← changed
)

# Everything else stays the same:
response = client.chat.completions.create(
    model="claude-sonnet-4-6",  # or gpt-5, gemini-3-pro, deepseek-v3, llama-4-maverick
    messages=[{"role": "user", "content": "Hello!"}]
)

JavaScript / TypeScript

import OpenAI from "openai";

// Before:
// const client = new OpenAI({ apiKey: "sk-..." });

// After:
const client = new OpenAI({
  baseURL: "https://api.brainiall.com/v1",  // ← changed
  apiKey: "brnl-..."  // ← changed
});

const response = await client.chat.completions.create({
  model: "claude-sonnet-4-6",
  messages: [{ role: "user", content: "Hello!" }]
});

Step 3: Test it (15 sec)

Run any existing OpenAI call. The SDK works identically. chat.completions, embeddings, images, audio.transcriptions all forward to 104 models.
