Not a dictionary — a map of how the field's language actually evolved. 400 terms that shaped the AI conversation: which ones emerged when, who coined them, which became standards and which stayed hype, and how they connect.
Built by cross-referencing 22 frontier AI models across three waves, then reviewed against 1230 external references. Entries show their available sources and maturity basis; coverage varies by term.
How the vocabulary grew
Each wave was generated blind to add only new terms — so they show genuine expansion, not repetition.
Signal vs hype
A term's maturity is how settled it is — not how important. Click a band to filter.
Definitions are AI-generated paraphrases (not direct quotes) reconciled across 22 models and verified against sources; ⚠ marks emerging terms still settling into the discourse. Content CC BY 4.0.
