Compare by the work
You do not need to know the pair first.
Choose the decision you are facing. The builder sets the useful layer and scorecard, then leaves the two candidates for you to choose.
The Human Bit comparison method
Judge the final work, including the work needed to trust it.
Benchmark scores and launch claims can orient a test. They cannot decide which complete workflow is acceptable for your organisation, information and consequences.
Hold the task constant
Use the same source pack, instruction, tools, time and acceptance criteria.
Score the usable result
Judge the corrected file, report or answer—not the most impressive first response.
Count the human review
Include factual corrections, source checking, file repair and explanation time.
Keep the decision accountable
Name who chooses, what trade-off they accept and what evidence could change it.
Freshness and evidence
A comparison should show when its facts may have changed.
Each option shows its own review and recheck date. Overdue records remain visible only with an explicit warning so they can be reverified before they influence a decision.
