Overview
Our free house model. It returns deterministic synthetic completions so you can exercise the gateway end to end — auth, streaming, usage accounting — before connecting a provider key. Always available, and the only model anonymous visitors can call. It answers in prose and never calls tools, so requests carrying `tools` are refused here rather than answered blind.

Latency p50 reflects a provider’s API endpoint responsiveness — the round-trip to its API, not per-token inference time. These figures, with throughput and uptime, are reference data until the gateway aggregates its own traffic.
Price comparison
