Decode the Jargon of Artificial Intelligence

Decode the Jargon of Artificial Intelligence

A Curated Glossary of Common Artificial Intelligence Jargon, for Project Managers

Now in it Edition 5.4 (21 May 2026), with a total of 215 definitions and an enlarged (57 entries) Acronym Decoder.

The fifth edition of this glossary was a substantial increment (over 20%) on the previous version, 4.5. It contained an additional 30 terms and 13 acronyms that were not in the previous edition. 

Editions since 4.0 have been AI-enabled. For the fifth edition (5.0), I asked ChatGPT, for new jargon, terminology, and acronyms that have appeared since the start of 2025. It suggested 6 terms I had not collected myself. 

Edition 5.4

With only an additional 6 definitions and 2 more acronyms, the reason I put version 5.1 out so soon after 5.0 was the term AI Psychosis. It’s not a clinical term, but it is strongly indicative of the way AI is affecting society. 

This edition, number 5.4, of Decode the Jargon of Artificial Intelligence adds over 40 more terms, including the wonderful Slopsquatting. For this one, I asked ChatGPT, Gemini, and Claude to suggest new terms that had arisen in the last 6 months. Please get in touch if there are any terms or acronyms you think I should add to this glossary.

This version of Decode the Jargon of Artificial Intelligence now includes 6 Special Features and explainers interspersed among the glossary items:

• Understanding Differences: AI Agents and RPA
• Understanding Benchmarks
• Forms, Causes, and Fixes of Bias in Artificial Intelligence
• The Layers of a Large Language Model (LLM)

Please get in touch if there are any terms or acronyms you think I should add to this glossary.
