What issue are you seeing?
I'm using Codex via the Codex CLI and also the Pi CLI. Responses have been coming too slowly since last Saturday, I think, especially when it falls back to SSE from WebSocket.
What steps can reproduce the bug?
Configure the Codex CLI via ~/.codex/config.toml to use SSE explicitly, like:
model_provider = "openai-sse"
[model_providers.openai-sse]
name = "OpenAI"
wire_api = "responses"
requires_openai_auth = true
supports_websockets = falseThen start a new session. Codex takes at least 5 minutes to answer.
What is the expected behavior?

@GGBondBlueWhale Yep, looks like there are a bunch of open issues already. I ran into this one while using Pi, and it seems the Codex backend's SSE connection has some problems.
same issue
This appears to be linked to https://github.com/anomalyco/opencode/issues/29079. OpenAI's SSE endpoint appears to not respond well -- sometimes leaving an empty response, especially for oceania users.
Yep confirm that I'm seeing the issue on Opencode too
See my issue, it's the same https://github.com/openai/codex/issues/24260
I encountered the same problem
I got the same problem in codex app
I can resolv this problem， Maybe you use vpn, and then you have five reconnecting, after that, is thinking. but it is too slow,
so you need to use TUN Mode clash. It can work to me
unacceptable slow
generating an prompt for image generation takes minutes.
recreate a few kb of hmtl 15 minutes an up.
WIndows codex desktop app hangs several minutes.
Everyting ist 20x times faster in Chat Web Window. Payed 200$ for that shit.
I use both Codex and Opencode with a chatgpt subscription. Codex is at least 3 times slower
@hannespreishuber 30 minutes one image :(, 20-30 minutes for small coding task.
