changes made to get working on windows.

[danjp93]

notable fix was to replace depreciated model versions (e.g. claude 3.5) with current available versions (4.6)

• Just as a note, I had a similar idea to yours and implemented mine last month: https://github.com/danjp93/digresser
• It's not as nice as yours! Thought it would make more sense to contribute some of my ideas to your repo (eventually)

Let me know if you want me to implement some sort of unit tests.
