I'm guessing I'm not totally alone when I say my head shape doesn't easily fit into the standard oval hat block shape used for most hats.

I have a few of those relatively inexpensive hat stretchers (Hat-jacks) that they sell at just about every good hat store. The first time I used one I was really happy to have found a tool that could help me relieve the front-to-back pressure I get with nearly all hats.

I initially shaped my hat-jacks in a way that I thought was more closely aligned with the actual shape of my head. After using them on multiple hats for more than a year, I was seeing some shortcomings with the design.

The text will be off! Even though rectangles are perfectly centered.

Thus, that module was deprecated in favor of Nelson's OpenAPI::Client::OpenAI module. Throw the 13K+ lines OpenAPI spec for OpenAI at it and it just works. Further, the module is pretty much a single Perl class rather than a bunch of hand-crafted code.

CPAN authors know it can be hard to keep modules up-to-date (mea culpa, mea culpa!) and this module is no exception. I need this module so I offered to collaborate and created a PR to update it to version 2.0.0 of the OpenAI spec. It now passes all the tests (for those wondering, you need an OpenAI key and it costs $0.04 USD to run the test suite).

In trying to build a Whisper pipeline for that, I found that I couldn't. There was a PR for Whisper support for the older module, but for the newer one, I can't figure out how to get it to issue a request with multipart/form-data support. I've noted the issue in the PR.
