Composer Predictions in Codex
Composer predictions is a beta feature in OpenAI Codex that suggests a user's next message based on the conversation.[1]
Availability
| Requirement | Beta support |
|---|---|
| Client | Codex desktop app, local or SSH threads |
| Account | Personal ChatGPT Pro, age 18 or older, all supported regions |
| Models | GPT-6 Astra and GPT-6.1 Sol |
Chat on web or desktop is excluded.[2]
Using predictions
After Codex replies, a prediction may appear in the message box. Tab inserts it without sending. Users can edit it, submit it, or write something else. Predictions propose whole messages, not word-by-word completion, and never automatically send follow-ups.[2]
The default-on switch is Show predictions in Settings > General > Composer.[2]
Context and usage
Predictions use the current thread, including memory or connected-app context already present. They do not retrieve those sources independently and work with memory disabled.[2]
During the beta, generating predictions costs nothing extra and consumes neither credits nor Codex usage allowance. Sending accepted text incurs normal usage limits and billing.[2]
Missing predictions
Suggestions may take seconds, especially in long threads, or be skipped. Check the app version, setting, account, model, and thread type.[2]
