That started to shift this year, though, especially as the team at Codex really focused on compaction to change the way that people could interact specifically with Codex through a single unified thread.

Codex's Nick Baumann wrote back in April, "So much coding agent design is built on the assumption that breaching context windows and compacting context yields progressively worse results.

When you drop this assumption, the product direction it opens up is very exciting." He was responding to developer Anthony Kroger, who had written, "I literally never worry about context windows using Codex.

It can compact like three times, and the model still remembers the details somehow." In a post about a week later, Nick from the Codex team expanded on his thoughts in a piece he called My Codex Threads Are Alive.
