I've been using it in https://double.bot (vscode coding copilot I'm hacking on) and it's been pretty great so far. We have support for all the top models (gpt4o, deep seek, opus, etc) so I regularly like to switch between them especially if I see a challenging problem. So far, sonnet 3.5 has the best quality and is the one I use by default.
