Tibo's Day 5: text your dot from the ChatGPT mobile app, plus composer predictions on desktop

#What happened

Tibo (Thibault Sottiaux, OpenAI's Codex product lead) posted Day 5 of his 28-day daily-improvement series on X on October 9, 2026, with two items. First, the Dots edition: you can now create and text your dot entirely from the ChatGPT mobile app. He noted many users had already created dots via the desktop or web app, and said it is time to scale. Second, composer predictions in the desktop app. He said they often lead to a double take with how on point they are, and they are included in the Pro plans without consuming usage.

#Why it matters

Dots creation started as desktop-only, so bringing it to the mobile app widens the rollout beyond desktop setup users. Composer predictions arriving inside Pro plans at no usage cost is a meaningful perk for heavy Codex desktop users watching their meters. This continues the daily-ship cadence: Day 2 made Codex Auto-review free, Day 3 celebrated 40M active users with a banked reset, and Day 4 shipped instant steering plus GPT-6.1 Sol ultrafast.
