The AI Models I Actually Use in March 2026 (And Why I Changed Everything)

I spent months using a mix of AI models without much science behind it. A bit of Claude here, some GPT there, with the logic that " expensive = better." Spoiler: that logic was completely wrong. A few weeks ago I got tired of paying without knowing exactly what I was buying. So I decided to do something I should have done long ago: a systematic benchmark. No "it feels better" - real numbers, real tasks, category-by-category evaluation. The result was uncomfortable. Models I had on the podium failed at basic things. Models I'd barely considered crushed them on my real tasks.
