Still from the clip posted with this case; watch it in the original post on X.

Ran Unreal Tournament 99 on two Windows 98 PCs with each player driven by a language model, one being Jev.

Where this case fits

Filed under games & playable demos. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the games & playable demos page.
