How it works
- 1
Connect a provider
Paste your OpenRouter key. It's encrypted on our server and never shown again.
- 2
Chat with any connected model
Pick a model for each message, or let Auto choose one that's available.
- 3
Call it from code
Point any OpenAI SDK at Free Model with your own API key.
One key for every model you connect.
Point any OpenAI SDK at Free Model. Use an exact model ID, or "auto" to move to another connected model when one is rate-limited.
API setupapp.py
from openai import OpenAI
client = OpenAI(
base_url="https://freemodel.io/api/v1",
api_key="sk_…",
)
reply = client.chat.completions.create(
model="auto",

)Questions
Is it free?
We only route to OpenRouter models ending in :free with zero-priced inference. OpenRouter sets account rate limits; when a model is rate-limited, Auto tries another available free model.
Why do I need my own key?
Free limits apply per account. With your own key the allowance is yours, and you can revoke it at the provider at any time.
Are my chats saved?
No. A conversation stays in the open tab and is gone when you close it, start a new chat or sign out. Request records contain usage metadata such as model, tokens, status and timing, not conversation text.
Can I send images or files?
Not yet. Some models accept images upstream, but chat and the API here are text-only for now.
