About SemIf

SemIf (formerly OpenJev) Semantic ifs from open models, on a 3090 at home. Independent project; not affiliated with Jev or TypeSafe. Wow! No waitlist. Run it in your browser today. Same frozen 4B model · same state · same 21 questions · measured separately, aligned at t=0 in the replay Independent research project. SemIf was formerly called OpenJev. It is not affiliated with or endorsed by TypeSafe. Jev, TypeSafe, and other names and marks are the property of their respective owners. No infringement is intended. Most agent decisions are small: route this, retry that, does the evidence support X? A chat model can answer them, but it spends time generating text that software immediately parses back into an statement. Jev is TypeSafe's closed service for runtime-defined semantic decisions. This project reproduces that interface pattern with open models; it does not reproduce Jev's undisclosed model or training. This baseline reads typed option probabilities directly from a model. No answer sentence, JSON repair, or decoding loop. Latest changes — 2026-09-18 Added MiniCPM5 2B and Qwen3.5 4B to the browser demo. Added Uns

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
