decider-2b-vision
Mapika's vision decider: decider-2b v5 text weights transplanted into the Qwen3.5-2B vision-language model, tuned so an image plus a lettered question returns a calibrated probability at one answer slot with no generation. Breakout from pixels scores 41, above its teacher's 22.

AI 海龟汤 (Jev Situation Puzzle)
21GitHub stars
An open-source turtle-soup (situation-puzzle) game where Jev hosts: every yes, no or irrelevant answer and the final verdict on a reconstruction come from Jev live, with confidence gating a cannot-be-sure reply. Single-player, 8-player rooms and UGC submissions.
