Developer builds open registry to catalog and compare System One AI models

A developer and founder of systemonemodels.tech has launched a public registry cataloging all known System One model families, a category of AI models that answer typed, structured questions in a single forward pass without generating text. The registry emerged after more than fifteen such model families appeared within ten days of TypeSafe AI coining the category with its Jev model. Each listing includes details on maker, size, context window, licence, pricing, and reported accuracy figures. The founder notes that published accuracy numbers are not yet comparable, as each model is benchmarked on different test suites, and meaningful evaluation requires testing on one's own labelled data. The registry is free to browse and publish to, and includes a CLI tool for local fine-tuning on custom datasets.
