03 / THE SCORECARD
Judge the finished work, not the demo.
Give every model the same context and constraints. Score each dimension from one to five, then include the time you spent correcting the answer.
Writing control
Can it follow tone, audience, structure and length without sanding away your voice?
Answer quality
Does the answer solve the task accurately, completely and at the right level of detail?
Speed
Is it responsive enough for the way you actually work, including revisions?
Value
Does the result justify its credit cost for this particular task?
DON'T CHOOSE BASED ON OUR OPINION
Test them yourself.
04 / A FAIR TEST
Five rules that make the result worth trusting
- Use real work.Choose a task you repeat, not a trick question designed for a leaderboard.
- Hold the prompt constant.Same context, constraints, requested format and deadline for every model.
- Define success first.Write down what a correct, useful answer must contain before you see any output.
- Run more than one example.Include an easy, typical and difficult case so one lucky result cannot decide.
- Count correction time.The cheapest or fastest response loses if it creates more work before acceptance.
