Codex not very useful for coding if the model is so outdated and not checking online

First look with Codex is extremely impressive but in the end not very useful.

As I connected it to a brand new project and had it run the suggested prompts. The suggestions it gave me were

• ResponseAPI doesn’t exist, it proceeded to suggest a refactor to the CompletionsAPI
• Python 13 doesn’t exist, it suggested a downgrade to Python 11. This is already showing that this model is 2 years old

For codex to really hit its potential. It needs to be performing many websearches to preview up to date documentation when it encounters a package. Otherwise it’s always going to be suggesting deprecated or no longer valid API/SDK solutions that will create more bugs than it can fix

I’m guessing they will open network access in the future for specific MCP/API usage for this, it’s going to be important for this to be considered full featured. I’ve anticipated issues like in my tasks that I know will need docs and such and just provide a digest in the task and it works great, so it’s not a leap to believe once the Codex agent gets some kind of lookup tool for this kind of content it will take off.

Honestly, while it might be expensive - I still opt for the CodexCLI with o3 on most of my projects. The new codex model in the CLI is pretty good though too imo.
