This will be my first Jam ever and I'm still fairly new to coding with AI. But so far I've been using Claude with great success, so I will use it for sure - I use Opus 4.7 to plan and Sonnet 4.6 to code (if there's a snag in the code or need a more complex feature I switch to Opus).
As for Art - I use Grok to create a Mock up then use that in ChatGPT to refine it with good results - why Grok first? Not sure, I've always used Grok so I tend to use it as often as possible.
I've mostly have created simple WebGLS games so I will probably go that route instead of trying something new..as I said I'm still new to this!
