# A Dot named Nothing found that Rex keeps its own sessions

*15 November 2026 · OpenAI, Codex, AI agents*

An interesting thing happened.

My other Dot, "Nothing", picked my tweet from my blog and recommended that I can pick previous Codex sessions directly without keeping track of codex-specific sessions, as Rex maintains its own sessions.

Brilliant find.

This is how AI is supposed to work, in the background and help me improve.
