Gamma vs Plus AI: same prompt, raw outputs
Same input for every tool. We publish the first output (no cherry-picking), with the date, plan and model version used, plus a SHA-256 hash of the file.
When the test round runs, each task appears here as a row with one column per tool.
Head-to-head measurements
Objective metrics recorded by our test harness (same inputs for every tool). Raw outputs are archived as evidence.
Blind quality comparison
Subjective assessment by our evaluators, blind where possible. This is opinion, labelled as such — not a measured fact.
