OpenRouter free models
What this free AI model router setup does
An AI model router chooses which LLM your app should call. This page publishes a daily ranking of free OpenRouter models: use models[0].id as the primary model and keep openrouter/free as the fallback.
OpenRouter performs the actual routing and inference. shir-man.com only publishes the recommendation and copyable configuration; it never receives your prompts or API key.
Is OpenRouter free? OpenRouter offers free models, but availability and rate limits can change. This page refreshes the free-model shortlist daily; you still create and use your own OpenRouter API key.

How the free model router is ranked
- Free text models only Start with OpenRouter models that are free to use, return text, are not expired, and have at least an 8k context window.
- Metadata base score Score the eligible pool for tool calling, structured outputs, reasoning support, context length, output size, recency, and free-label confidence.
- Health and latency check When the backend has an OpenRouter admin key, it sends tiny throttled health probes to the top candidates and adds reachability plus latency points.
- Lite agent eval The likely winners get small file-writing, shell-command, and symbolic decoding checks. The eval stage stops once no unevaluated candidate can still overtake the leader.
- Cache and confidence Recent evals can be reused with decay. Account rate limits pause measurement; model-specific failures add a small instability penalty. Confidence rises when the winner is mathematically settled.

Keep a backup route
If the top pick stops working,
openrouter/freestays on the page as the fallback router so you can keep calling OpenRouter directly.
Final score = metadataScore + healthScore + latencyScore + liteEvalScore - instabilityPenalty.
The recommendation is a practical heuristic for general developer usage, not a benchmark claim.
Privacy
Your app routes through OpenRouter directly
shir-man.com does not proxy your prompts, collect your API key, or handle your completions.
Create your own OpenRouter API key, store it as OPENROUTER_API_KEY, and use the base URL shown above.
If the recommended model stops working, switch the model ID to openrouter/free. OpenRouter will route the request to any compatible free model it has available.
