Frontier Model
The top-tier models sitting at the leading edge of AI technology at any given moment — the latest flagship versions of GPT, Claude, and Gemini.
In plain words
This term refers to the most advanced models that sit at the frontier of AI technology at a given point in time. The latest flagship versions of GPT, Claude, and Gemini fall into this category, and the handful of companies that build them are called "frontier labs."
It's also an official term used in regulatory documents. Since the most powerful models carry the greatest risk, AI regulations in various countries impose additional obligations specifically on "frontier models."
