I've used a wide variety of the "best" models, and I've mostly settled on Opus 4 and Sonnet 4 with Claude Code, but they don't ever actually get better. Grok 3-4 and GPT4 were worse, but like, at a certain point you don't get brownie points for not tripping over how low the bar is set.

People have actually been basing their assertions on 4o. The bar is really low and people are still completely missing it.
