Free AI that
actually works today.
Free models die, rate-limit, and resurrect without notice. We probe every one of them each morning and tell you which are alive right now.
Bring your own key
Squeeze the catalog
Probing runs entirely in your browser. Your key is stored locally, sent only to OpenRouter, and never touches a server of ours — there isn't one.
No key? Grab a free one at openrouter.ai/keys. Every model tested here costs $0, so probing is free too.

PASS made a real tool call — Claude Code can drive it. WEAK answered but ignored the tool schema. FAIL errored or timed out. Only PASS models go into your config.
How it works
Probe before believing
A listing isn't a promise. Every model here answered a real request, with a real tool schema, today.
Discover
Every $0 model in the OpenRouter catalog, pulled live. Nothing hardcoded, so nothing rots.
Probe
Each one gets a real tool-call request. Answering in prose isn't passing — agentic work needs tools.
Publish
Survivors are tiered and shipped as a config, plus a machine-readable roster your launcher can fetch.
For the terminal
Skip the browser entirely
The engine is open source. lime.sh
fetches this morning's roster, merges your key, and rotates across passing models so no single
free tier carries all your traffic.
