Finest is an LLM-API Gateway (Domain: finest.so) that automatically routes requests to the most cost-effective model configuration meeting the customer's defined quality standard. The system measures each request against its own production traffic rather than generic Leaderboards and re-validates routing decisions with every new model release. It offers OpenAI/Anthropic-compatible access via a single Base-URL (existing SDKs remain usable) as well as a specialized product "Finest Code" for Claude Code that reduces API costs without changing the workflow. Billing follows a "No cure, no pay" model: costs only as a share of demonstrated savings.
