I get the Pro version for free since I’ve worked on a few popular open-source projects. I’m using it in VS Code and it’s helped me write code for systems I’m unfamiliar with. I’ve used it to summarize the architecture of open-source projects so I understand how to contribute new features. The autocompletion can be pretty good too. I also use it to review my code.

We use Claude Code with the Opus 4.5 model at work, and it’s quite a bit better, but I don’t want to pay that much for an AI model for personal projects since I use it so infrequently.
