Open VSX Codex for Windows releases not available since Version 26.721.30844 #39476
Description
Activity
Confirmed this independently on Windows x64 with VSCodium.
- VSCodium is configured to use Open VSX.
- On 2026-09-07, uninstalling and reinstalling the stable openai.chatgpt extension installed version 26.721.30844 for win32-x64. It was neither pinned nor installed as a prerelease.
- Process inspection confirms that the running extension app-server is the bundled bin/windows-x86_64/codex.exe from that extension installation.
- That executable reports codex-cli 0.146.0-alpha.3.
codex debug models --bundledreturns eight models and no gpt-6-astra entry.- An IDE session explicitly configured with
model = "gpt-6-astra"records originator=codex_vscode, source=vscode, provider=openai, and cli_version=0.146.0-alpha.3. - Its startup request fails with HTTP 400:
"The 'gpt-6-astra' model requires a newer version of Codex. Please upgrade to the latest app or CLI and try again." codex login statusreports that the client is logged in using ChatGPT. The same account sees Astra on chatgpt.com, although I understand that availability can differ between Chat and Codex.- A newly fetched models_cache.json records client_version 0.146.0 and contains no Astra entry.
- No custom model provider or base-URL override is configured. During the diagnostic check, OPENAI_BASE_URL was unset, no Headroom process was running, and nothing was listening on port 8787.
- Checked on 2026-09-08: the Open VSX target endpoints for versions 26.825.51511 and 26.901.22334 return 404 for win32-x64, while their linux-x64 and darwin-arm64 target endpoints return 200.
This means that a fresh Open VSX installation on Windows currently provides a Codex runtime older than Astra’s documented minimum version of 0.153.0.
Could the team restore current win32-x64 publishing to Open VSX and confirm which IDE-extension release will first bundle a runtime containing the Astra catalog-visibility change from #42874, released in Codex 0.153.4?
This is still an issue and it is making my entire organization rethink using codex at all. We are stuck on this outdated version since our enterprise tools team guards against supply chain attacks and gates us behind open vsx. They block us from even visiting the official vs extension site and also lock down wsl.
VS code integration is essential for our workflows. We all (60+ people spending $15,000+ monthly) use windows 11 and have been stuck on this old version of codex extension for 2 or 3 months now.
There are CVEs on the current available open vsx windows version and I'm afraid info sec will ban the vulnerable version or it just stops working at which point we will have to convert our workflows to claude code or copilot.
I'm wondering if fixing this issue is even on radar. if not I may as well start migrating before all our workflows break
Thanks for your attention,
Tim@tmeindle - I read somewhere that you can download the latest Codex VSIX through regular Microsoft VS Code and install it whatever OpenVSX VS Code derivative you require. I have been using it successfully (so far) for Devin Desktop (formerly Windsurf).

I work at a very large, highly locked down enterprise. Corporate infosec has the official vs code extension store blocked in vs code itself and in browsers. It is blocked on corporate firewall. Everything is gated through proxies. The version of vscode they allow us to install through their enterprise appstore is set up to connect to openvsx for extensions.
Even if there was a way to install the updated version through another source, corporate policy forbids unauthorized software sources with penalties including termination of employment I would not risk it. Thanks for suggestion though
I'm not now nor ever suggesting subverting company / organization (cyber)security policy. I'm merely informing of another approach. On your end I might suggest having to escalate through your management and / or corporate IT helpdesk to let them know that this has been an issue now for I think a few months and as such could they investigate this alternative approach in a way that would or could be an officially supported method for receiving VS Code extension updates (perhaps specifically this OpenAI Codex one). (Assuming of course that you haven't already gone down this path.)
Reacted by tmeindleYeah I was able to solve this problem just by switching to VS Code. I no longer use VS Code clones, I just use regular VS Code.
I'm experiencing the same issue with the Codex extension in Positron IDE on Windows.
Positron is a VS Code-based IDE designed for R and Python data science workflows. I use it for R programming and statistical analysis, and I rely on the Codex extension for AI-assisted coding.
Unfortunately, the latest Windows version available through Open VSX is still
26.5730.61309, while newer versions are available for Linux and macOS.The Positron development team has confirmed that OpenAI has stopped publishing updated Windows builds to Open VSX:
posit-dev/positron#16086Could the OpenAI team please resume publishing Windows builds to Open VSX?
This would be very helpful for Windows users of Positron and other VS Code-based editors that rely on Open VSX.
Is there an estimated timeline for resolving this?
Thank you!

However, there does appear to be newer releases for the Microsoft VS Code marketplace for the Codex IDE extension for the latest releases.
What steps can reproduce the bug?
Go to Open VSX website for Codex.
Try to download Windows on the latest (or any release over the prior four weeks) and you will not see a Windows download option.
E.g., using the following link:
https://open-vsx.org/extension/openai/chatgpt/26.814.41407
Navigate to the download button under "resources" section on right hand side.
What is the expected behavior?
Previously, Windows was a selectable option. E.g., you can see on the following release.
