GitHub added a permanent free tier for GitHub Copilot today, including access to both GPT-4o and Claude 3.5 Sonnet. My notes here: https://simonwillison.net/2024/Dec/18/free-tier-for-github-copilot/
@simon my team at MIT has had the pro/enterprise version of copilot enabled for a while and while I saw the announcement, I don’t yet see settings to link it up with ChatGPT or Claude.
I get a lot out of it as it is, but mostly in the capacity of being a hyper intelligent auto complete that I have presented as another option aside, my editor is LSP.
