keunwoochoi · x · 2026-07-13
The post mentions that Codex has removed its previous 5-hour window limit, significantly improving the user experience. Meanwhile, Claude Code still retains a session cap, though it is now simply referred to as a "session limit."
This type of update is highly practical for heavy coding agent users, as it directly impacts the viability of long-horizon tasks, continuous debugging, and multi-turn programming workflows.
