Just yesterday, it helped me parse out and understand a research paper - complete with step-by-step examples (this one: https://research.nvidia.com/sites/default/files/pubs/2016-03...). I will now go ahead and implement it myself, possibly relegating some of the more grunt-work type tasks to Claude code.
Without it, I would have been struggling through the paper for days, wading through WGSL shader code and there would be a high chance that I just give up on it since this is for a side project and not my $job.
It has been a major force multiplier just for learning things. I have had the $20 subscription for about a year now. I bump it up to the $100 plan if I happen to be working on some project that eats through the $20 allocation. This happens to be one such month. I will probably go back to the $20 plan after this month. I continue to get a lot of value out of it.
