Decisions (System One)

Answer typed questions using the Jev (TypeSafe AI)-compatible Decisions endpoint

Ask Bionic to read this page

Copy this prompt, open Bionic, and paste it into a new chat.

Read https://lmstudio.ai/docs/developer/jev-compat/systemone, I want to ask questions about it.

  • Method: POST
  • Endpoint: /v1/systemone
  • See llama.cpp docs: System One API

Use the identifier of a loaded decision model, not a regular chat model.

Provide state and a questions object keyed by question ID. Question types are noul (probability that a condition is true), choice (select from a criteria object), and score (rate against an ordered criteria array). Responses contain an answers object keyed by question ID.

Images must be inline base64 data URLs and require a model that supports image input.

    "model": "your-decision-model",
    "state": "I was charged twice.",
    "questions": {
      "angry": {"type": "noul", "instructions": "Is the customer angry?"}
    }
  }'

For the OpenAI-compatible request and response format, use Decisions.
