(ty developer here) This is an early preview of a pre-alpha tool, so I would expect a good chunk of those 3500 errors to be wrong at at this point :) Bug repor

  Any rough estimates of how much faster you expect ty to be compared to mypy? I'd be super curious to know! I was also one of those people who, when first trying Ruff, assumed that it didn't work the first time I ran it because of how fast it executed!

    We're looking forward to hearing what your experience is! There's a certain amount of roughly-constant overhead (e.g. reading all the files), so generally ty will look relatively faster the larger the project is. For very large projects we've seen up to 50-60x faster or more. We haven't really put a lot of work into targeted optimization yet, so we aim for it to get faster in the future. It will certainly be slower than Ruff, just because multi-file type analysis more complex and less embarrassingly parallel than single-file linting.
