Noul – yes/no decisions

The Noul node asks Laya a question that can be answered with yes or no, for example “Does the customer ask for a refund?” or “Is this message phishing?”. Laya returns the probability of “yes”. The node turns this number into a simple route that you can branch on with a Switch node.

When to use Noul

• A clear yes/no decision: refund requested, cancellation, complaint, phishing, reply expected, contains an invoice number …
• A safety zone: answers where Laya is not sure enough go to a human instead of being guessed.
• Several independent checks (“refund?”, “complaint?”, “cancellation?”): one Noul node per question, or all of them in one request with the Advanced node.

How the decision works

Laya returns noul, the probability that the answer is “yes”. Two limits split the range from 0 to 1 into three parts:

0          0.15                         0.85         1
|── no ─────|──────── unsure ────────────|──── yes ───|

Examples with the defaults: 0.93 → yes · 0.04 → no · 0.60 → unsure · 0.30 → unsure.

Result

Result contains Laya’s answer unchanged, plus route. Example for “You charged my invoice twice, I want my money back!”:

{
  "type": "noul",
  "noul": 0.9815,
  "confidence": 0.9815,
  "answer_confidence": 0.9815,
  "action": { "act_probability": 1.0 },
  "model": "laya-rl-agent",
  "usage": { "input_tokens": 226, "state_tokens": 40, "truncated": false, "...": "…" },
  "routing": { "model": "multilingual", "detection": { "language": "en", "...": "…" } },
  "route": "yes"
}

Branching with a Switch node

Noul has one output. Connect a Switch node behind it and add one condition per route:

msg.laya.route == "yes"
msg.laya.route == "no"
msg.laya.route == "unsure"

📷 Image placeholder: Screenshot of a flow Noul → Switch with three branches (yes / no / unsure), e.g. “refund process”, “normal answer”, “human review”.

You can also use the raw value, for example for an extra strict path:

msg.laya.noul >= 0.95

Batch mode

With Batch on, every record in Text gets the question in one request (up to 64 records per request; more are split automatically).

Input

msg.text = {
  "T1": "You charged me twice, please refund.",
  "T2": "Great service, thank you!",
  "T3": "When is your office open?"
};

Result

{
  "T1": { "type": "noul", "noul": 0.91, "route": "yes", "...": "…" },
  "T2": { "type": "noul", "noul": 0.03, "route": "no",  "...": "…" },
  "T3": { "type": "noul", "noul": 0.12, "route": "no",  "...": "…" }
}

With a list as input (["…", "…"]) the result is a list in the same order. Each entry has exactly the same fields as without batch mode, including route.

Examples

Refund requests to accounting

1. Text: msg.email (object with subject and body)
2. Question: “Does the customer ask for a refund?”
3. Switch: yes → create a task for accounting · unsure → human review · no → continue normally

Phishing check: in doubt, block

1. Question: “Is this message phishing or a scam?”
2. Yes From 0.6 · No Up To 0.1 · If Unsure: yes (treat as yes)
3. Everything that is not clearly harmless is treated as suspicious.

Question from a variable

Set Question to Message scope and fill msg.question earlier in the flow. One Noul node can then serve several rules from a table.
