Normalization

Scaling each Score by its number of levels — dividing by len(criteria) - 1 — before weighting it in a composite.

Definition

Scores from different rubrics are not directly comparable: a 1.43 on a three-level scale and a 3.5 on a five-level scale mean different things. Composite scoring normalizes each by its top level so weights represent relative importance rather than rubric size.

The arithmetic stays in code. Jev's Score levels are weak at numeric calibration, so normalization is a bookkeeping step, not a correction for a measured magnitude.

Break a judgment into atomic Score questions, normalize each by its top level, and combine them with weights you control in code, as in the resume example's four scored dimensions.

Regex finds candidate emails, phone numbers, and amounts; Jev picks the requested span so code copies a verbatim value that cannot be invented, with no free-text extraction required.

LLMs generate answers, Jev makes decisions

this is the easiest way to understand Jev: LLMs generate answers. Jev makes decisions. that sounds like a small difference, but it actually changes the entire use case. say you give a normal LLM this: “here’s a user, their account history, payment behavior, support chats, Show more

TypeSafe AI

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

Arbitrary classification as a primitive

Jev is cool not because it re-invented classification, but because it makes ARBITRARY classification into a type-safe programmable primitive. A general purpose zero shot decision model whose native interface is RUNTIME-DEFINED typed decisions, optimized for that exact interface

If you called Yann LeCun an idiot for saying we need to move beyond LLMs and build something new, you are banned from using Jev.

Custom Jev-style models for agent workflows

Prediction: millionaires will be made using custom Jev style models (parallel constrained decoding) to make the agent systems companies already run more token efficient. Let me explain with a scenario: Imagine a company already has an agent workflow running where an llm reviews Show more

They were building in stealth for 2 years, I was building in stealth for 2 hours… Happy to open source Qwen-2.5-1B-RLCD, 5x faster on-device inference for JSON workloads that need to be type-safe. ⚡️Demo below on a M4 MacBook⚡️ every LLM has the ability to efficiently batch
