I'm dabbling more and more. It's been useful for trip planning for me. I had Grok create a packing list based on the destination (Sedona) and it took weather and everything into account. The list is less than I would normally pack so I'm going to follow it and see how it goes. I'm also using it for cooking/grilling/recipes. Lower res would have probably helped the speed of render but I have a feeling the slow speed is intentional to try to motivate people to pay the premium for "super-Grok".
