System One

I want to evaluate and, if it fits, integrate a technique from recent AI research into my project.

## Technique: System One
System One Models: Jev / Laya / CLM-8B — Fast Typed AI Decisions for Production Stacks

A new model category for fast, typed AI decisions instead of text generation. Jev (TypeSafe AI) delivers parallel typed output at 70–500ms, $0.042/M input tokens, no output token cost — 40–200× lower latency and 444× cost reduction vs frontier LLMs for routing/classification tasks. RLCD (Reinforcement Learning for Calibrated Decisions) gives well-calibrated confidence scores. Open alternatives: Laya (421M params, 33ms on T4, Jev-compatible API) and CLM-8B (contrastive embedding, 9× faster than Jev on large action sets, 81.6% on DeepSWE). New stack layer: rules → System One → LLM. Directly implementable for agent tool selection, ticket routing, content moderation, RAG reranking, guardrail gates, Jev-as-judge.

What the reference demo shows: 5-sub-tab Gradio demo — (1) Architecture Overview: three-tier stack and System One vs LLM comparison table; (2) Decision Schemas: interactive typed schema builder for 4 use cases; (3) Routing Demo: 5 simulated examples with latency/cost comparison; (4) Benchmarks: latency, cost, accuracy bar charts for Jev/Laya/CLM/LLMs; (5) Implementation Patterns: 4 drop-in code patterns (judge, router, RLCD threshold, open-source).

## My project
<Describe your stack, the problem you want to solve and where this technique would sit. Example: "Python FastAPI RAG service over 50k PDFs, Postgres + pgvector, OpenAI embeddings, p95 latency budget 800 ms.">

## What I need from you
1. Read the reference source code and explain in at most 5 bullets how the technique works and what it would change compared to my current approach.
2. Decide whether it fits my case. If it does not, say why and stop there.
3. Propose the smallest viable integration: files or modules to touch, new dependencies, configuration.
4. Implement it behind a flag or as a separate function so it can be compared side by side with what I have today.
5. Add an evaluation script that measures task success rate, number of steps and token cost per task, before and after, on my own data.
6. List the risks (latency, cost, failure modes) and what to monitor once it is in production.

Constraints: keep my existing stack and conventions, avoid heavy dependencies unless the gain is clear, and reference the file in the demo source whenever you reuse its logic.
