What it is

An experimental controller that lets TypeSafe's Jev model directly choose NES controller inputs for the original Super Mario Bros.

Getting started

From the README:

py -3.13 -m venv .venv
.venv\Scripts\python -m pip install -e ".[mario,dev]"
$env:TYPESAFE_API_KEY = "your-key"

Where the decision sits

typesafe-mario calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.

Models it references: Jev.

How active it is

We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
