PromptEngineer48/laya-vs-jev-arena

A two-game head-to-head you can play a side of yourself.

The repository's GitHub card, read on 2026-09-24

What it does

Runs Laya and Jev head to head in two games where each move comes from the model, and lets a person take one of the two places from a container.

The repository's own description: “Laya (open source, local) vs TypeSafe Jev (API): two AI models race in Snake and fight in a Mortal-Kombat-style arena. Every move is a real model decision.”

How it works

Both sides answer identical typed questions about the game state, so the model is the only difference between them, and the game itself renders the outcome instead of a scoring script.

What we checked

the README, read 2026-09-24
the docker command and the two game modes
the note that nothing in either game is scripted

What we did not check. Who wins, or how often. The repository is the arena, not a report of its results, and we have not run the container.

The topic

Every record, by kind of work The same rows cut a second way, across every column.
What self-hosting costs Hardware, memory, and the failure modes of running it yourself.
What the licence allows Apache-2.0 weights, three checkpoints, and the limits that come with them.

By kind of work

Runtime ports 23 Getting the weights onto someone else's hardware: MLX on a Mac, Core ML on the Neural Engine, ggml in C++, candle in Rust, ONNX in Node.
Serving and API 8 Standing the model up as something else can call, usually behind Jev's own wire format.
Agents and tools 6 Typed decisions inside an agent loop: routing, evals, guardrails, memory, and the plumbing around them.
Browser and computer use 2 Deciding the next click, key or field on a real screen.
Games and demos 9 The model playing something you can watch. Most of this model's traffic arrived through one of these.
Benchmarks and evaluation 19 Numbers somebody actually ran — including the ones that say Laya lost.
