Karpathy: Claude Opus 4.5 beats GPT-5 Pro for interactive history learning
doodlestein · x · 2026-09-27
Andrej Karpathy shared that Claude Opus 4.5 has become his go-to tool for learning history interactively — more engaging and better for retention than Wikipedia or most books. The key, he says, is speed: Opus 4.5 responds quickly even in thinking mode, making it far more interactive than GPT-5 Pro, where long waits break his focus (though latency matters less when he just wants the best answer for planning complex software projects). The post continues his earlier reflection that AI-driven interactive learning has replaced much of his book reading.
