True. That's the reason I see a lot of people dropping similar frameworks like LangChain recently: https://medium.com/thoughts-on-machine-learning/drop-langcha...

i was using vercel ai sdk for my production app and it was such a bad experience that I eventually went with native implementation and tbh it was not much of work thanks to cursor. problems i faced: too many bugs (just browse their github repo to get an idea), the UI side also had suboptimal performance based on how they implemented hooks.
