Definition
Plain language
One of the current most capable AI models — the cutting edge from major labs.
As stated in the literature
A leading-edge foundation model from a major lab, typically among the most capable available at a given time, used as a reference point in benchmarks and safety work.
Also called: frontier models
Why it matters: These models define what's currently possible and what new techniques need to beat, so they're the reference point for both capability claims and safety concerns.
For example, when a paper benchmarks against 'frontier models,' it usually means the latest GPT, Claude, and Gemini releases at the time of writing.
