Just 5 months ago, I was swearing at Claude 4 Sonnet like a Balkan uncle

Models one-shotted the right thing only 20-30% of the time but did really stupid things the rest, and had to be handheld tightly

Today they are much, much better. My psychology is a lot more at ease, and instead of swearing, I want to kiss them on the forehead most of the time

Now I trust agents so much that I queue up 5-10 tasks before going to sleep. They work the whole night while I sleep and I wake up to resolved issues

GPT 5.2 xhigh and Claude 4.5 Opus are already goated (GPT more so), can't wait for them to get even faster
