UnverifiedLLMs should be regarded as part of a system rather than an isolated component, as their output needs to work in concert with downstream processing pipelines and human review steps75% similarUnverifiedIntroducing LLMs means that data science teams need to master skill stacks including prompt engineering, retrieval-augmented generation (RAG), fine-tuning, and model evaluation.75% similarUnverifiedIn project scheduling, data schema design and pipeline construction should start in parallel with model evaluation, not after the model selection is finalized.74% similarUnverifiedThe core difference between reasoning models and ordinary LLMs lies in the training approach rather than the architecture; reasoning models introduce a reinforcement learning stage on top of pretraining and supervised fine-tuning.72% similar
