Frequently asked about Frontier AI Models
What counts as a frontier AI model?
A frontier model is a general-purpose AI system trained at the largest compute scales — models like GPT-class, Claude, Gemini, Llama and Grok — whose capabilities exceed prior systems on broad benchmarks.
How often are new frontier models released?
Major labs ship a flagship roughly every 6–12 months, with point upgrades in between. This hub updates on every confirmed release.
Where can I track frontier-model benchmarks?
Each article here cites the primary benchmark source — the lab model card or an independent eval — so you can verify the numbers directly.
