The toughest prediction any data scientist makes is deciding which tools are worth learning. The explosion of generative AI only makes this harder. My prediction: LangChain is here to stay or, at least, the patterns behind it are. The toughest prediction any data scientist makes is deciding which......

This time, I want to train a model with all the mistakes and fruitless efforts included. When I train a ma......
