Codex composer predictions: the next message, suggested

On October 9, 2026 OpenAI put composer predictions into beta in Codex. After Codex finishes a response, it can show a suggested next message in faded text. Press Tab to put it in the box, review it, and send it yourself.

Short version: it is a Pro-only beta in the Codex desktop app (local and SSH threads), on GPT-6 Astra or GPT-6.1 Sol. Predictions are on by default and do not use Codex credits, but the messages you send still count toward normal usage limits.

Who can use it

OpenAI’s announcement said “for Pro users”. Its Help Center article gives the eligibility above, so check your plan before you look for the feature.
