Frontier model
The most capable models out there at any given moment — the current top of the line, wherever the line happens to be.
Think of it like
The flagship phone of the year — until next year’s makes it ordinary.
Example
When a lab ships its newest, biggest model, that’s a frontier model until the next one lands.
How it actually works
It’s a moving label, not a fixed tier — today’s frontier is next year’s baseline. The term shows up most in policy and safety conversations, because the newest, most capable systems carry the least-understood risks and draw the most scrutiny before release.
For product teams
Highest capability, highest cost — reach for it when quality matters more than price.
For engineers
The current capability ceiling; typically the largest/newest models under active evaluation.
