Threw a complex task at an AI assistant—building a radio protocol spec from scratch—just to see how it'd handle it. After two solid hours of attempts across multiple iterations, the model hit a wall. Decided to switch gears and test the latest high-performance model variant on the same problem. Early impressions: noticeable differences in approach and problem-solving depth. Worth tracking how this plays out over the next couple hours. If you're working with AI on protocol implementation or similar technical specs, the model choice genuinely matters.
