Free Tier (10 models)
The free tier is 10 reasoning, coding, and vision models with no per-token
charge. The lineup is kept current by a self-healing health gate that routes
around any model whose upstream is temporarily unavailable and auto-recovers
it, so existing calls keep working. All free-tier models are FREE for both
input and output — call GET /api/v1/models for the current live list.
