AI agent spends a day chasing a simpler proof of Fermat’s Last Theorem

A user says they are watching an AI agent comment on its own work as it goes, and the internal monologue is so mathematically advanced that it becomes funny to an outsider.

In context, the agent is Codex Sol (Extra High), which has been running since yesterday in an attempt to find a simpler proof of Fermat's Last Theorem than the modern state of the art. The commenter says it has not made any big breakthrough yet, but it is making small steps on subproblems.
