What subscription do you have?

ChatGPT Pro

Which model were you using?

gpt-5.1-codex-max xhigh (or whatever model you actually selected)

What platform is your computer?

macOS (please specify version, e.g. macOS 15.x, Apple Silicon)

Codex CLI is running inside:

• Cursor IDE's integrated terminal
• Google Antigravity IDE terminal

What issue are you seeing?

When I use speech-to-text on macOS to input a Chinese + English mixed sentence into Codex CLI, the recognized text does not appear in the Codex input line after the dictation finishes.

The text only appears (or gets sent as a full message) after I press Enter or trigger a newline / any keypress.

This seems to happen starting from the second conversation in the same Codex CLI session. The very first conversation usually behaves correctly.

The issue reproduces consistently both in:

• Cursor’s integrated terminal
• Antigravity’s Codex CLI integration

So it feels like a Codex CLI TUI / paste handling issue rather than an IDE-specific one.

What steps can reproduce the bug?

Rough repro steps:

1. On macOS, start Codex CLI in a terminal (e.g. Cursor integrated terminal or Antigravity terminal) and sign in with my ChatGPT account.
2. Start the first conversation:

• Place the cursor in the Codex input line.
• Use macOS speech-to-text / IME voice input to dictate a sentence that mixes Chinese and English.
• After dictation finishes, the text appears in the input line as expected. I can edit it and send it. (First conversation is OK.)

1. In the same Codex CLI session, start a second conversation / follow-up:

• Again use the same speech-to-text workflow with Chinese + English mixed content.

1. Actual behavior:

• After dictation finishes, the Codex input line remains empty, as if nothing was pasted.
• When I press Enter (or otherwise trigger a newline / keypress), the entire dictated text suddenly appears or is sent as a single message.

This pattern is reproducible every time for me, in both Cursor and Antigravity terminals.

What is the expected behavior?

• After speech-to-text finishes, the recognized text should be immediately inserted into the Codex input line, for every conversation (not only the first one).
• I should be able to see and edit the text before sending it.
• Pressing Enter should only submit the text, not “magically reveal” previously invisible input.

Additional information

• This behavior started only after the last two Codex / Codex CLI updates.

Before those updates, the exact same workflow (same Mac, same IDEs, same speech-to-text method) worked perfectly.

• I’ve already upgraded Codex CLI to the latest version and rebooted macOS; the issue still reproduces.
• Speech-to-text works fine in other applications (plain text editors, browser text inputs, etc.), so it doesn’t look like a system-level dictation problem.

I also noticed a very similar issue reported as “Codex CLI copy paste issue” (#7203) on the codex repo, where large pasted text does not appear until the user presses a key.
My case looks like the same underlying TUI / paste-handling problem, but on macOS with Chinese + English mixed speech-to-text input.

I think this has been fixed with recent changes to the paste burst algorithm in Codex. If you're still seeing this with the latest version of Codex, let us know.
