SemIf open-sources a Jev-style interface: typed option probabilities from a 4B model, no JSON parsing

JeremyCMorgan · x · 2026-09-25

SemIf (formerly OpenJev) is an open-source project replicating Jev's interface with open models: it reads typed option probabilities straight from a frozen 4B model, skipping text generation and JSON parse/repair entirely. Runs on an RTX 3090, Apple Silicon via MLX, or in-browser over WebGPU — no waitlist. Independent of Jev/TypeSafe, it reproduces the same frozen model, state, and 21 questions with measurements aligned at t=0. Core idea: most agent decisions (routing, retries, evidence checks) can be made directly from probabilities rather than generated text.
