Dana builds and re-runs a fixed evaluation harness against every model and coding tool Model Drop reviews, so a rating from March means the same thing as a rating in August. She previously worked as a machine learning engineer shipping retrieval systems, and she is allergic to vendor-supplied benchmark charts that don't disclose the prompt set. If a company won't tell her what's in their eval, she runs her own and says so.
