Top comment

I built Sysone to make small AI decisions easier to use in TypeScript: does this need a reply, which team should handle it, which retrieved passages are relevant? The library keeps the probability and gives yes/no checks an explicit uncertain state. Several independent questions about the same input fit into one evaluate() request. Collection operations make one request per item. It has zero runtime dependencies and is 3.9 kB min+gzip including all providers. Provider and model are separate: Jev works through TypeSafe or Vercel AI Gateway, with an experimental adapter for compatible self-hosted endpoints. The site has a shared Jev playground, copyable examples and an executable native-fetch comparison. The library is MIT licensed. Version 0.5.0 is available as a GitHub release; npm registry publication is still pending. Which real decision would you try it on?
