Liquid d1

liquid/d1 is Liquid AI's first decision model. Send state and typed questions (noul / choice / score) to POST /api/v1/decisions and get calibrated probabilities back in one call, with zero generated tokens — not chat text. It fits classification, ticket and model routing, scoring, moderation, guardrails and LLM-as-judge checks.

• Terminal — anyr decision --model liquid/d1 (Decisions app).
• App code — plain fetch to /api/v1/decisions, see the example below.

Liquid d1 is **BYOK-only**, served by Liquid's own API. Create a key at console.liquid.ai (Dashboard → API Keys) and add it under Dashboard → BYOK — AnyRouter charges nothing for a BYOK route, and Liquid serves the model as a free tier. Setup steps: Liquid BYOK.

  },
  body: JSON.stringify({
    state: "I have been waiting three weeks for my order and nobody answers my emails.",
    model: "liquid/d1",
    questions: {
      is_complaint: {
        type: "noul",
        instructions: "Is this message a complaint from the customer?",
      },
    },
  }),
})
console.log(await res.json())
