About Conifer
Summary
Conifer builds an AI inference router that selects the model, provider, and cache strategy for each query automatically. It sits inside existing development harnesses, so tools like Claude Code and Codex require no reconfiguration. The product replaces manual model selection and provider management, cutting the inference costs companies pay across a fragmented landscape of hundreds of models and providers.
Business model
Cloud tokens billed at the model's own rate with no upcharge; the runtime, router, and local inference are free.
Go-to-market
Developer teams at B2B companies adopt it self-serve by installing the runtime and minting an API key, with no changes required to their existing AI tooling setup.
From the Y Combinator listing
Least cost routing system to reduce 80%+ token spend
There are thousands of models, providers, and harnesses, each with its own pricing and strengths, leaving an overwhelming number of choices when it comes to managing token spend and intelligence. Conifer uses intelligent routing and orchestration logic to handle the full path of each query: model selection, provider choice, and cache management. It all runs inside your existing harness, so tools like Claude Code and Codex work without changing your setup. By centralizing where inference occurs, Conifer lets companies save on their inference bill while leaving teams free to focus on what they are building.
