💡 Likely answer: A maintainer (etraut-openai, contributor) responded on this thread — see the highlighted reply below.

What version of Codex is running?

codex-cli 0.7.0

Which model were you using?

o3 via azure

What platform is your computer?

Linux 5.10.237-230.949.amzn2.x86_64 x86_64 x86_64 (sagemaker studio terminal)

What steps can reproduce the bug?

run codex, and then just ask it a simple question (eg "hello, are you there?"), the llm call finishes but it doesn't reply in chat. It consistently does not reply in the chatbox.

(see section below for the output)

it is able to do bash operations and write code, and actually if you ask it a question and ask it to output the answer to a file, it will do that too.

I get the same behaviour (not replying) in v0.4.0 as well.

What is the expected behavior?

It should be able to reply. Eg working below with v0.1.2505172129

run it with RUST_LOG=debug and then tail -F ~/.codex/log/codex-tui.log to see if that tells you anything interesting.
