ChatGPT 5.5 Pro の最近の体験：博士レベルの研究を1時間で生成

ChatGPT 5.5 Pro is capable of producing a piece of PhD-level research in an hour or so, with no serious mathematical input from a human. The claims that LLMs are now capable of solving research-level problems could initially be laughed off, as many of the solutions had an answer sitting in the literature already or could be very easily deduced. It has now gotten to the point where, if a problem has an easy argument that for some reason human mathematicians have missed, then there is a good chance that the LLMs will spot it. This post looks at how ChatGPT 5.5 Pro fared with a selection of problems.
