Codex suggests the next message
Researched retrospectively on 13 October 2026. A new beta helps draft the next instruction. Accepting a suggestion remains the user’s decision.
Next steps can appear as a suggested message
On 9 October, OpenAI announced Composer predictions in Codex beta. The current conversation can produce a suggested next message. Tab accepts it for review or editing; acceptance does not send it automatically. The beta is intended for personal ChatGPT Pro accounts aged 18 and over in supported regions, using the latest Codex desktop app and supported models.
What it means: Our interpretation: Suggestions can help draft instructions, but need review.
Example: For example, add an edge case to a suggested test request before sending it.
