Migrate from OpenAI to Brainiall in 60 Seconds

Step 1 — Sign up (15 seconds)

Go to chat.brainiall.com/auth/login. Sign up with Google OAuth or email. No credit card required. Free tier available.

Step 2 — Get your API key (10 seconds)

Dashboard → API Keys → Create new key. Copy the brnl_* token.

Step 3 — Change base_url (30 seconds)

Replace OpenAI's default base_url with Brainiall's. That's the only code change.

Python

# Before
from openai import OpenAI
client = OpenAI(api_key="sk-...")

# After
from openai import OpenAI
client = OpenAI(
    api_key="brnl_...",
    base_url="https://api.brainiall.com/v1"
)

Node.js

import OpenAI from "openai";
const client = new OpenAI({
    apiKey: "brnl_...",
    baseURL: "https://api.brainiall.com/v1"
});

cURL

# Before
curl https://api.openai.com/v1/chat/completions \
  -H "Authorization: Bearer sk-..." \
  -d '{...}'

# After
curl https://api.brainiall.com/v1/chat/completions \
  -H "Authorization: Bearer brnl_..." \
  -d '{...}'

Step 4 — Optionally switch model (5 seconds)

Brainiall's 104 models work with the same API shape. Switch model with one parameter:

# Use OpenAI GPT-5 (default)
client.chat.completions.create(model="openai/gpt-5", messages=[...])

# Or Claude 4.6 Sonnet
client.chat.completions.create(model="anthropic/claude-sonnet-4-6", messages=[...])

# Or Gemini 3 Pro
client.chat.completions.create(model="google/gemini-3-pro", messages=[...])

# Or DeepSeek V3.5
client.chat.completions.create(model="deepseek/deepseek-v3.5", messages=[...])

Does my existing OpenAI streaming code work?

Yes. Brainiall supports streaming, tools/function calling, vision, structured outputs — same API shape.

Can I keep using OpenAI's Python/Node SDK?

Yes. The openai package itself is unchanged. Only the connection params (api_key + base_url) change.

What about embeddings, image, voice?

Embeddings: Same API (/v1/embeddings). Image: Brainiall ships Seedance + GPT-5-image (instead of DALL-E). Voice: ElevenLabs included. Video: Lyria 3 (OpenAI doesn't offer video).

Can I migrate gradually?

Yes. Use environment variable for base_url. Switch traffic gradually:

BASE_URL = os.environ.get("LLM_BASE_URL", "https://api.openai.com/v1")
client = OpenAI(api_key=KEY, base_url=BASE_URL)
# Set LLM_BASE_URL=https://api.brainiall.com/v1 to use Brainiall
