Agreed if you are building a typical service. The abstractions will slow you down and don’t and anything.

The use case where they are helpful is “bring your own keys” apps. I maintain https://github.com/kiln-ai/kiln which allows you to bring keys for 13 different providers. The abstraction is very much worth it for me.

That said:

- I migrated from LangChain to LiteLLM and never looked back

- I have over 1000 automated integration tests that check the grid of LLM features (tools, json), model, and provider. Without them it would still be a mess.
