# Laya / System One

> Use Laya on SGL Grid for typed decisions, scoring, and private System One workflows.

Laya is the open-source System One model served on SGL Grid as `convaiinnovations/laya`.
Use it when you need structured decisions instead of chat text: route choices, scores, or compact
`noul` answers.

<Warning>
  Laya is not a chat-completions model. Call `POST /v1/systemone`, not
  `POST /v1/chat/completions`.
</Warning>

## Quickstart

```bash theme={null}
curl "https://grid.x402compute.cc/v1/models?type=systemone" \
  -H "X-API-Key: $SGL_API_KEY"

curl -X POST https://grid.x402compute.cc/v1/systemone \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $SGL_API_KEY" \
  -d '{
    "model": "convaiinnovations/laya",
    "state": {
      "ticket": "Enterprise customer cannot access billing exports",
      "customer_tier": "enterprise"
    },
    "questions": {
      "route": {
        "type": "choice",
        "instructions": "Choose the best team to handle this ticket.",
        "criteria": {
          "billing": "Billing, invoice, refund, or account credit issue.",
          "support": "Product defect or technical troubleshooting."
        }
      },
      "urgency": {
        "type": "score",
        "instructions": "Score urgency from 0 to 1.",
        "criteria": ["customer blocked", "money at risk", "security risk"]
      }
    }
  }'
```

Typical response:

```json theme={null}
{
  "object": "systemone.result",
  "model": "convaiinnovations/laya",
  "answers": {
    "route": { "type": "choice", "choice": "billing", "confidence": 0.83 },
    "urgency": { "type": "score", "score": 0.7 }
  },
  "usage": { "input_tokens": 178, "output_tokens": 0, "cost_usd": 0.000001 }
}
```

## Privacy Modes

Plain `POST /v1/systemone` validates and routes plaintext through the orchestrator, then dispatches
only to attested confidential nodes. This is private at the node/runtime layer.

For end-to-end private Laya, use the reserved sealed flow:

1. `POST /v1/systemone/reserve` with `model` and `input_tokens_upper_bound`.
2. Encrypt locally to the returned node X25519 key.
3. Submit the sealed payload to `POST /v1/systemone`.
4. Decrypt the sealed result locally.

In the sealed flow, the orchestrator sees ciphertext while the node decrypts locally and runs Laya
inside its serving boundary.

## Limits

## Operators

Node operators can serve Laya from Singularity Node app v1.7.4 or newer: open **Models → System One
→ Laya** and connect. The app manages a local loopback sidecar at `127.0.0.1:8765` and starts the
normal SGL node service with the System One runtime attached.

See [Node setup](/cloud/provide/node-setup) for the operator path.
