What it is
PlayJev is a fine-tune of Qwen3.5-0.8B-Base that plays ten classic browser games directly from raw pixels, aimed at real-time GUI-game agents and Jev-style decision models.
How it uses Jev
For each step the model receives the current frame, plus the previous frame when velocity matters, and the game's list of moves. Its single forward pass returns a probability over those moves; the game loop takes the argmax, and low-confidence steps can be handed to the per-game teacher.
Primitives:choice
Technique worth stealing
Shuffle the move list in every training sample so position carries no information.

Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
