While everyone was obsessing over ChatGPT’s latest updates, Anthropic quietly dropped a bombshell that’s about to reshape how we think about AI coding forever. Claude 4 isn’t just another incremental upgrade—it’s the first AI model that can actually think before it codes, and the results are nothing short of revolutionary.

The “Holy Shit” Moment That Changes Everything

Claude Opus 4 just scored 72.5% on SWE-bench, the gold standard for measuring AI coding ability. To put that in perspective, that’s like an AI getting an A- on the hardest computer science exam ever created. But here’s the kicker that nobody’s talking about: this isn’t just raw intelligence—it’s sustained intelligence. Unlike every other AI model that gives you its first (often flawed) instinct, Claude 4 has something called “extended thinking.” It literally pauses, works through problems step-by-step in its head, and then gives you the answer. Think of it as the difference between a brilliant student who blurts out answers versus one who takes time to think through the problem methodically.

Yes. Indeed, this is first new (lazy) blog post in a long time!

Over the years I’ve been playing with the various versions of the GPT model and as the case with many folks recently, I’ve been fascinated by ChatGPT. So, I decided to dust-off my old blog and get really lazy by letting ChatGPT blog for me. I typed the following into ChatGPT:
