That's true. We traded API compatibility work for SDK compatibility work. Our bet is that providers are better at maintaining their own SDKs than we are at reimplementing their APIs. SDKs break less often and more predictably than APIs, plus we get provider-implemented features (retries, auth refresh, etc) "for free." Not zero maintenance, but definitely less. We use this in production at Mozilla.ai, so it'll stay actively maintained.
