I tested GPT-5's coding skills, and it was so bad that I'm sticking with GPT-4o (for now)


In my latest coding benchmark, GPT-5 stumbled badly, delivering broken plugins, flawed scripts, and confidence-laden wrong answers that could derail projects without careful human oversight. Here's what to know before you use it.

But the fact that it gave me back a non-working plugin on the first try is fail territory, even if the AI did eventually make it work on the second try. It's really a test of the reach of the AI in terms of knowledge, its understanding of how web pages are constructed, and the ability to write code across three interlinked environments. Ever since the whole generative AI thing kicked off at the beginning of 2023, ChatGPT has been the gold standard of programming tools, at least according to my LLM testing.
