GPT-5-Codex in Cursor - Feedback Needed

Those of you who had the chance of using Codex in Cursor, what do you think about it so far? Better than GPT5, Claude 4 Sonet, or just unjustified hype? To us…it’s been a total mess so far (24h of usage), so we would love to hear others’ take on this.

Totally useless. Slow and not working.

if you like baby sitting 3 year olds and approving shell commands every 4 seconds it is great! I disabled it in config file and not a bit of change. Pure trash imo for now.

They say they’re supportive, but I couldn’t find it in Cursor.

it is the extension. not the model. or maybe I am mistaking it.

gpt-5-codex is model name, extension id is openai.chatgpt

For some things it is amazing, for others it is absolute trash.

In windows 11 doing commands on wsl2? Really bad.

In windows 11, creating something it has direct access to and can test/verify? Great.

I ran it for about an hour with the first thing and it didn’t accomplish anything good. 2 minutes of Claude code inside wsl2 and it was done.

The other thing ran for about an hour and was completely good to go.

Is it natively available on Cursor now, or still via the extension? Messy with the chat on the left side.

They said that they had made a mistake in changelog and that they would announce when the GPT-5-Codex would actually become available.

Any updates on a rough idea of when the gpt-5-codex model will be available for use in Cursor natively(without OpenAI’s Codex extension)?
