I’ve been building AI agents for long enough now to have developed a healthy reflex: whenever a new frontier model drops, my first question isn’t “is it smarter?” It’s “does it change the shape of the code I have to write?”
Most releases don’t. They nudge a benchmark, shave a few cents off a token, and the agent loop I wrote last quarter still looks the same the next morning.
Claude Opus 4.8 is one of the rare ones that does change the shape.
