Two years ago, reasoning models did not exist. GPT-4o and Sonnet 3.5 were SOTA.
One year ago, the best publicly available model was o3, and 99% of those who used it (i.e., 99% of 7% of OpenAI customers) were using it as a chatbot.
Today (i.e., right now as I type this), I have Codex building several pieces of personalized software and doing a large-scale data management project for me. The data management project has been running autonomously for nearly 4 days. I have multiple working apps on my phone that I use daily and which were built entirely by Codex.
Projecting this trend to June 2027 is absolutely mind-boggling. The world will change.
