OpenAI 28-Day Sprint Day 14: Codex Can Finally Edit Historical Messages Within the Original Conversation

Beating AI News Flash: OpenAI's Head of Product and Platform, Tibo Sottiaux, announced Day 14 of the 28-day product sprint. Codex desktop now supports directly editing historical messages within the same thread. For example, if you're halfway through writing code and realize a requirement from several rounds earlier was written incorrectly, you can go back and edit it, then continue the conversation from that point.

A user asked whether this is equivalent to giving the Agent supplementary instructions mid-way. Tibo replied that it's more like "time travel." Codex previously supported forking conversations, but users have long wanted to directly edit old messages in the original conversation without having to open a separate branch. Tibo also acknowledged that this feature had been requested for a long time and the team took too long to ship it.
