Microsoft favors Anthropic over OpenAI for Visual Studio Code by Tom Warren

It’s a tacit admission from Microsoft that the software maker is favoring Anthropic’s AI models over OpenAI’s latest GPT-5 models for coding and development. Sources familiar with Microsoft’s developer plans tell me that the company has been instructing its own developers to use Claude Sonnet 4 in recent months.

I have been in this boat myself. I was using Claude (Pro) this past month.

I am mostly happy with it. I was about to buy yearly subscription for it, there are same savings to it.

But then, OpenAI updated codex with a new release optimised for coding. And so I thought, before pulling the trigger and subscribing for a year let me give ChatGPT a go as well for a month.

Also, I am missing cursor agents. And codex does have agents. That might prove to be useful.
