Where Laya fits

Laya is Convai Innovations’ open System One-style decision model. You pass state and typed questions; you get probabilities, not prose.

Use Laya when you want decision-model behavior with deployment control, not another chat completion.

Last verified: October 2026. Background: Laya review, what is a System One decision model.

Top use cases

1. Support ticket triage (customer service workflow)

Choice for owning team, Score for urgency, Noul for refund or escalation. Same playbook as Jev; Laya matters when tickets must stay inside your VPC.

2. Multilingual intake and routing

Use the multilingual checkpoint when IVR, chat, or email arrives in many languages. Route to locale queues or bilingual agents. Validate on your language mix; do not assume English accuracy transfers.

3. Email routing and threat triage

Mailbox Choice plus Noul flags for phishing or social engineering. Pair with deterministic detectors (links, auth headers). Laya is one signal, not the whole SOC.

4. Intent detection for assistants

Closed intent Choice with a human-handoff Noul. Keep option descriptions crisp. Huge intent taxonomies need a shortlist stage first.

5. Content moderation

Policy Scores and Nouls in one pass. Publish / review / remove thresholds live in application code so product can tune without retraining.

6. Lead scoring from free text

Fit Score + persona Choice from form dumps and CRM notes. Good volume job for a cheap decision model. Bad job if you need a written qualification narrative.

7. Agent tool routing and model-tier selection

Pick tools or model tiers with calibrated Choice/Score. Open weights help regulated teams that cannot send agent traces to a third-party API.

8. Invoice and document action picking

Specialist typed-decisions checkpoint territory: primary action on an invoice packet (approve, request info, escalate). Still not OCR or extraction; pair with your parse pipeline.

9. Security incident triage

Classify incident class and next action from alert text or JSON. Useful as a first-pass router before expensive analyst tools.

10. Agent-trace observability judgments

Score or Choice over “is this loop stuck?”, “did the step succeed?”, “should we page?”. Designed for traces, not for writing the incident report.

Checkpoint notes

Checkpoint signal	Use it for
General Laya	Broad English decisions
Multilingual	100+ language intake
Typed-decisions specialist	Invoices, security, CS, agent traces

Specialist checkpoints can underperform outside their workflows. Do not silently auto-route every request to the specialist.
