Ty isn't a compelling option. If you want support for dynamic libraries, mypy is king. If you want speed and strict conformance, Pyrefly and Zuban are better.
Ty's original pitch was that it would have strong inference and be useful for gradually typing existing, untyped codebases, but AI made that moot. Adding types to existing code is now trivial.
