Updated this chart with the newest Gemini. It shows the rapid progress in AI over less than two years: costs for GPT-4 class models has dropped 99.7% and even the most advanced models (beating PhDs at the GPQA) are still 82% cheaper than GPT-4. Probably not worth betting on this trend ending soon.

Evidence that a well prompted LLM can help learning from a (small, single-subject) randomized controlled trial at Harvard: “here we show that students learn more than twice as much in less time with an AI tutor compared to an active learning classroom, while also being more engaged and motivated.”
