Yea learning how to use the core API directly should be the focus for any engineer. Lots of frameworks built on top of LLMs are being made very quickly each with their own philosophy. It's a good time to stay with the fundamentals as much as possible until the dust settles. Learning langchain will take you less than a day if you have fundamentals don't worry about not staying up to date. Now's the time to learn how LLMs work from the ground up not being a framework chaser. (watch Karpathy's GPT from scratch video and read through huggingface's LLM documentation from RLHF to PEFT fine-tuning)
