Dev Slams Claude 3.5 Opus as 'Benchmaxxed', Claims It Feels Dumber in Practice

Prominent developer evilsocket expressed deep frustration with the Claude 3.5 Opus model on social media. He complained that during his daily, hands-on testing, the model feels and acts significantly dumber than version 4.8 (likely referring to GPT--4.8 or a similar competitor).
He suspects the model was heavily 'benchmaxxed'—optimized specifically to score high on public benchmarks—at the expense of real-world performance and usability in complex workflows.
