What is a frontier model?
Definition
AI conceptsFrontier model
A frontier model is one of the most capable AI models available at a given time, usually the top tier from a major provider.
Why it matters for schools
Frontier models usually make fewer errors but cost more, and free consumer tiers often run smaller models: free ChatGPT runs on OpenAI's smallest Luna models, while the $20-a-month Plus plan adds GPT-6 Sol reasoning. For learning, the rules matter as much as the model. Without learning rules, a stronger model can make outsourcing easier.
In practice
Budgets apply to every model. Promise students a fair share of strong models under class rules, not unlimited access.
