SemIf: semantic 'if' decisions with local open models, entirely in your browser

ngxson · x · 2026-09-19

SemIf on openjev.com is a live, backend-free experiment in semantic conditionals: an open model reads probability distributions over your allowed options without decoding them, or writes the same distribution token by token, so you can compare both on your own GPU.

Model choices: Qwen3 0.6B (639 MB, phones), MiniCPM5 2B (1.56 GB, desktop), Qwen3.5 4B (3.01 GB). Authored balanced accuracy: 44% / 68.6% / 81.3%; TypeSafe agreement on a public 102-row subset: 40.7% / 63.7% / 84.5%, vs. a published Jev value of 88.3%. Weights cache in-browser from Hugging Face and inputs never leave the page.
