Use AI! It'll make you a 10x engineer! (cost-wise) /s

I've recently had the displeasure of Opus 4.6 hallucinating an API. It would have been great if that API had existed, but it did not. Still, it then looped until I manually terminated it while trying to make tests pass. In my case, I used up about $12 of usage in 30 minutes. My guess would be mostly through the (pretty verbose) thinking tokens.

But it's not just Anthropic. I had the same issue with Gemini 3.1 Pro.
