Model and Effort Decision Matrix (September 2026)

A decision matrix for choosing which Claude model to use and how much effort to ask for. It treats model and effort as two separate dials, shows where to start for common tasks, and tells you which dial to turn when a result falls short.

What's inside

For professionals who want good results from Claude without defaulting to the biggest model at the highest effort.

Brain, Grit, Speed: model, effort and fast mode explained as three separate choices
A side-by-side of the current models, with each one's default effort and what it is for
The five effort levels, from low to max, and the work each one suits
The Knew or Tried test: find out whether Claude did not know or did not try, and fix it the right way
A starting-point matrix for six common task types, and a worksheet to compare settings on your own task

The Knew or Tried test
Wrong facts or shallow reasoning: it did not know, so use a bigger model. Skipped files or a lazy summary: it did not try, so raise effort. A simple job overdone: lower effort.
