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. LangChain’s job is to drag non-deterministic GenAI outputs into a deterministic world. Putting GenAI into real workloads demands the right mindset from a data scientist. We’re not training the models that generate the answers; we’re taking those answers and fo...
