What the chart shows

This is the AI hiring wave, measured. For years 'machine learning' and 'NLP' carry a steady research-flavored slice, with PyTorch overtaking TensorFlow as the framework teams name. Then the generative-AI surge after 2022 reshapes the whole group: 'AI' and 'LLM' climb fast as the work shifts from training models to building products around them. The relative bands separate genuine, durable demand from hype; the sample postings show the move from research roles to applied LLM, retrieval and AI-product engineering.
