What today’s job postings actually ask for. Pick a role and a period - skill frequencies are counted across deduplicated postings, with links back to every source job.
A quick overview of what this role tends to mean, drawn from the wording of the postings themselves.
Applied AI work centers on production models, not just research prototypes. Transformer and foundation model work is common, especially for agentic systems. Python and PyTorch dominate; R appears in analytics-heavy environments. NLP and LLMs show up in customer-facing and reasoning-focused roles.
