ChatGPT Codex Computer Use vs Claude Cowork
I've been running both. Here's where Codex computer use is hard to ignore.
Here's what I covered:
- Tested ChatGPT Codex's computer use against Claude Cowork
- Spotify, found and played a podcast on a specific topic
- ClickUp, pulled a conversation thread and turned it into a to-do list
- Online shopping, added Rao's Marinara to a cart and checked out
- My take on which one to use when
ChatGPT Codex 5.5 launched with computer use built in, and after running real tasks through both Codex and Claude Cowork, the speed and accuracy of Codex's computer use is the part that surprised me. It opens apps on your computer. It uses them. It does it fast.
I asked it to find a podcast in Spotify on a specific topic. It opened the app, searched, and started playing in seconds. I had it pull a thread inside ClickUp and turn it into a to-do list. It did. I asked it to add Rao's Marinara to my cart and check out. It did that too.

Both Codex and Claude Cowork are useful for different jobs. Cowork shines as a long-running collaborator for marketing work. Codex's computer use shines when you want raw speed on real desktop apps. If you're choosing one, you don't have to. Use them where each one is strongest.
