What's in it
Four cards, one per model, each with a depth and speed reading and two or three tasks it's actually good at. A rule of thumb at the bottom: start with Sonnet, go up when the answer isn't good enough, go down when you just want it fast.
Who it's for
Anyone who opens Claude, sees a model picker, and guesses. No benchmarks, no context-window numbers, no pricing tables — just what each one is for.
Print it
It's a single Letter page with a light background, so it prints cleanly in colour or greyscale. Stick it next to the desk of whoever keeps asking you which model to use.
