Make the vendor inherit your AI controls.

A health system that runs Miso gives an approved vendor an endpoint. The vendor's application uses the models and providers the system has already approved, under the system's agreements. The vendor never holds the system's provider credentials, and its model is pinned to the version it validated.

If you're the vendor: a base URL, a credential, two headers.

Miso is OpenAI-compatible. Name the route you're registered for and, where the policy requires it, the patient the request is about. The rest of your integration stays as it is.

# before base_url = "https://api.openai.com/v1" # after base_url = "https://gateway.northstar.health/v1" headers = { "Authorization": "Bearer <caller credential>", "x-gateway-route": "encounter-note-draft", "x-gateway-subject": "<mrn>" # when the route requires it }

What the vendor gets.

The system's agreements

Its BAAs with Anthropic, Azure, and Bedrock cover your traffic through the gateway. You negotiate none of them.

A shorter security review

The model-and-data section of the questionnaire becomes a registry entry: your name, your routes, your purpose, your pinned model. Diligence on your application is still the system's to do.

Your obligations on every response

Human review, disclosure, subject identification: what's expected comes back with each call.

Your own evidence

The pages of the monthly report that cover your traffic are sent to you, for your auditors and your other customers.

Newer models when the system approves them

When the system approves a new provider or version, it can offer you the move. You agree before your pin changes.

A pinned model, by design

Model selection belongs to the system's own teams. Your route runs on the version you validated.

What's asked of the vendor.

  • Send the route name and, where required, the patient identifier the request is about
  • Acknowledge the obligations returned on each response, in your own system
  • Keep your BAA with the health system current; the registry holds its review date
