It's not super clear how this differs from another recently released library from Microsoft: Guidance (https://github.com/microsoft/guidance).

They both seem to aim to solve the problem of getting typed, valid responses back from LLMs

One of the key things that we've focused on with TypeChat is not just that it acts as a specification for retrieving structured data (i.e. JSON), but that the structure is actually valid - that it's well-typed based on your type definitions.

The thing to keep in mind with these different libraries is that they are not necessarily perfect substitutes for each other. They often serve different use-cases, or can be combined in various ways -- possibly using the techniques directly and independent of the libraries themselves.
