First, GoModel is designed to be flexible. If you add an extra field, it tries to pass it through in the appropriate place (Postel's law)

Therefore there's a good chance that if they make a minor API-level change, GoModel will handle it without any code changes.

Also, changes to providers' API formats might be less and less frequent. Keeping up typically means adding a few lines of code per month. I'm usually aware of those changes because I use LLMs daily and follow the news in a few places.

As a fallback, GoModel includes a passthrough API that forwards your request to the provider in its original format. That might be useful when an AI provider changes their contract significantly and we haven't caught up yet.

Also, official SDKs aren't bug-free either. Skipping that extra layer and hitting the API directly might actually be beneficial for GoModel.
