Frontier model

A frontier model is one of the most capable general-purpose AI models available right now, and right now is doing heavy work in that sentence. The frontier moves every few months, occasionally every few days, and yesterday’s marvel can become the option you scroll past by Thursday. These models attract attention because they handle broader tasks, longer context, more complicated reasoning and tool use; they raise the floor of what can be automated and extend how far a machine travels through a job before asking for help. The book avoids hanging its argument on one product name because product names age like yoghurt in a hot car. A smarter model completes more of the task. It does not become trustworthy, tasteful, courageous or responsible because a benchmark number went up. Capability moves. Accountability stays with us.
