The only "official" integration is GitHub Copilot. It's well integrated into everything else, but you can only use it with Copilot. There's a number of AI assistant-related extensions , but I've never seen anyone talk about any of them specifically. The VS Extension ecosystem is pretty dead, I think they are trying to revive it with the new Extensibility framework. Codex seems to be its own independent tool though, so I don't know how exactly you'd integrate that. Answer from Mickenfox on reddit.com

June 6, 2025 -
Googling seems to turn up nothing, but I thought I'd give one last shot here.
Looks like the CLI tool could be run in any folder, but it would be nice with a VS integration with a prompt and user interface.

r/OpenAI on Reddit: Codex extension for VSCode
August 28, 2025 -
I tried using the new Codex extension for vscode today with high reasoning with my peasant Plus plan. I used it for physics based applications and I am honestly very impressed.
Before, I used to use GPT5 thinking model for brainstorming and then generating prompts for Sonnet 4 to code but now Codex it does all of it in the same prompt. The coding accuracy and reasoning is top notch. For me, it has crossed the threshold where I can say I don’t need Gemini (for reasoning) or Claude (for coding) anymore. It also can process multiple workflow in the background while you discuss the next steps with it. It’s crazy good and save a lot of time.
The number of requests also seem to be reasonably high on the Plus subscription: 30-150 per 5 hours.
Let me know your experiences.

It’s crazy good for me! Somehow the Cloud version was not good enough for me earlier, now they must have updated the model recently or I might have gotten better with giving prompts. I use it to generate synthetic data for Data Analytics demos using faker and dbldatagen. Initially it was struggling with errors specially around limitations of MS Fabric’s PySpark, T-SQL, namespace format, etc. But then I created a guideline file and would ask it to update the guideline every time it made a mistake and corrected it. Now, it’s flawless, no more errors. Also the real life scenarios it brings in for synthetic data generation logic is really good.
