Fronset
An OpenAI-compatible inference API that routes each call to the cheapest model good enough for it.
Fronset is an OpenAI-compatible inference API. You send a request in the shape you already use; we route it to the cheapest model that is good enough for that particular call, and we publish the measurements behind that judgement.
Start here
- Documentation — quickstart, the data and control planes, errors, and what happens to your data.
- Pricing — what it costs, the free tier, and the two funding modes (bring your own provider keys, or let us manage them).
- Status — live availability and the support commitments that go with each tier.
- Legal — the Terms, the DPA, the privacy policy and the per-tier data grants.
The measurements
Routing decisions are not opinions. Every model we route to is scored on real production workloads, and both the scores and the method are public on the benchmark.
