Codex ends turn unexpectedly #10828

@collinbentley1

Description

@collinbentley1

What version of Codex CLI is running?

codex-cli 0.98.0

What subscription do you have?

Pro

Which model were you using?

gpt-5.3-codex

What platform is your computer?

Darwin 25.2.0 arm64 arm

What terminal emulator and version are you using (if applicable)?

Terminal.app

What issue are you seeing?

After switching to gpt-5.3-codex, I notice that Codex regularly stops after displaying responses that strongly imply it will proceed with the given task.

For example:

" Understood. I’m continuing now with that exact comparison and will return
results only once complete."

But the conversation has stopped (so no follow up response will ever be received)

and then following up with

"continue"

yields another

"Still in progress — running the cross-engine diffs now (PGSQL tables vs DuckDB
*_latest views) and gathering mismatch summaries + sample keys."

but there is no "Working..." message or visible tool call being made, since the turn has ended/shifted back to me.

What steps can reproduce the bug?

019c303b-53a0-75d3-8349-ba9f571bdda6

What is the expected behavior?

No response

Additional information

I've cleared AGENTS.md, ensured personality is None, and have scanned config.toml for anything unusual, but I see no obvious issues other than change of model.
