Learn Jev
Educational hubs for System One in plain English. Meet Choice, Score, and Noul, then jump to gateway wiring, the Jev alternatives hub, and comparisons like Laya vs Jev. Agent tool setup lives on /guides.
choice
Pick one label from a list. You get choice, probabilities, and confidence.
score
Rate state on a rubric. You get score, probabilities, confidence.
noul
Is this statement true? You get a noul value from 0 to 1.
Laya vs Jev compared
Run typed decisions on your own machine, or call hosted System One in the cloud. Same kind of question, very different homework. Independent comparison hub while open-weight Laya is trending: checkpoints, Laya-MLX on Mac, benchmark fairness, and hybrid patterns with hosted Jev.
Laya vs Jev compared: open weights or hosted API
Same typed primitives, different deployment. Read this before you rip out a working Jev integration on a Friday afternoon.
What is Laya?
Convai's open decision family: one forward pass, Choice / Score / Noul, Apache 2.0. Not a tiny chatbot wearing a trench coat.
Laya-MLX on Apple Silicon
Community MLX runtime for local Laya inference. Fast short decisions on a Mac. Not an official Convai build.
Benchmarks and fairness
How to read Convai's Laya vs Jev tables and laptop MLX numbers without fooling yourself (or your CFO).
Agent setup guides
LangChain, Cursor, Copilot, and other how-tos are on the guides hub, separate from these primers.
Guides
Jev & TypeSafe
A primer for builders who need to know what Jev is, who it is for, and when TypeSafe docs should take over from this directory.
System One model
The model family behind Jev: parallel typed questions, one forward pass, probabilities you can threshold.
Jev vs LLM classification
When to gate with System One probabilities instead of asking a chat model to label things.
Vercel AI Gateway Jev
Try typesafe-ai/jev through Vercel's gateway and the AI SDK evaluate path.
Where to run Jev
Compare official TypeSafe, Vercel AI Gateway, OpenRouter, Cloudflare Workers AI, and classifier.dev with a fact table.
Jev use cases
The patterns builders actually search for: moderation, routing, triage, RAG verify, and agent gates.
