I had two Heavy accounts, $600/month US, but I upgraded / downgraded as needed, so my costs were more like $200-300/month. Then like many of us I got frustrated and decided to cancel both. At cancel, they offered $100/month for 3 months. So I cancelled one account and have been upgrading downgrading the remaining when I want to generate.
Here's my current take.
Even labotimized, Grok is still pretty amazing. I got used to a higher level of quality and yes, things are now shite in comparison, but what is possible at shite level continues to intrigue me. To avoid moderation and burning up tokens, I avoid compute prime time which for me (EST) is from 6pm to 11pm. Ask grok when compute is at a premium in your time zone and don't generate then.
Some mornings I'm up between 5-7 am to burn up all my Imagine tokens for that day, usually the reset is after midnight. Then I do my other life and come back for more the next morning. I usually get about 100 x 720 videos/day, lots of extends.
Back in the day, we shot film and waited days for the film to be processed. We created a 3D render and waited hours for the render to complete. I used to run complex renders all night long. So what's happening with Grok is annoying to be sure, but folks, welcome to the wild west. AI everything is going to be a cluster fuck and if we want to play close to the edge, we might fall off. Complaints are probably registering with corporate as are cancellations, but after complaining, make something with whatever tools are available.
