How to read it

  • Shows the ten specialised skills most often listed in US AI job postings in 2025, with their counts for 2013–15. A posting can list several skills.
  • The AI Index does not say whether the 2013–15 figure is a three-year total or a yearly figure; its growth rates (+391% for Python) compare the two directly, as we do.
  • The AI Index text also says Python postings rose nearly 30% from 2024; the data file has no 2024 values, so we do not use it.
