Vynaris
OpenAI-compatible gateway that routes each request to a smaller model and returns a cost receipt
Vynaris is an LLM gateway that sits behind an OpenAI-compatible endpoint and picks which model serves each request. Set the model to "auto" and it starts from a frontier model and downgrades when its evals support it, or name a model directly and it gets right-sized.
Every response carries a receipt in the headers showing the model that served the request, the provider's cost, the routing fee and the final charge, exportable as a CSV ledger. Point an existing OpenAI or Anthropic SDK client at the base URL and the rest of the stack is unchanged; documented setups cover Claude Code, Cursor and OpenClaw.
Billing is provider list price plus a 3% routing fee, dropping to 1% past $500 of monthly usage. There is no free tier: fixed plans start at $5/month and convert to API credit, or prepaid top-ups start at $50. Vynaris also hosts its own reduced-refusal Qwen and DeepSeek variants, which require a $50 balance.
