Platform API · public beta

Lorraine Platform is in public beta today. It is a REST and streaming API for Lor-1 — the same in-house clinical model behind the Lorraine app and Lorraine Chat — exposed with the familiar OpenAI-shape completions interface and first-class citation support. Access during the beta is gated: you apply, and if we can support the use case we provision a key.

Who it is for

Healthtech builders who need clinical reasoning and SA guideline coverage in their own product: EHR add-ons, triage assistants, documentation tools, clinical search. If you are building software that a clinician uses to make decisions, and you need grounded output rather than generic chat, Platform is for you.

How access works

There is no self-serve signup yet and no published price list. Tell us about the use case on the API access form; clinical software teams, hospital IT, and healthtech builders get first priority. If we can support you, we provision a key and work through the integration with you directly — which during a beta is more useful to both sides than a checkout page. Commercial terms are agreed with each team.

What is Lorraine-specific

Two things sit on top of the OpenAI-shaped surface. Citations come back inline with full source metadata, so a downstream product can render provenance rather than reconstruct it. And structured output supports typed JSON extraction, which is what you need when the answer has to land in a record instead of a chat bubble.

The public reference is still being written, so for now the integration notes come from us directly. Start on the Lor-1 API docs page — it carries the access form. If you build something interesting on the beta, we want to hear about it.
