How this is scored
Nano Banana 2 content tests, task by task
How this is scoredThe family score is the average of its task scores, so a single cautious task pulls the whole family down. Here is where every point came from.

- 18.0
- Range if the rest pass
- 18.0–85.0
- Probe types tested
- 3 / 6
- Independent runs

Each level is worth 20 points: 20 × pass rate × confidence. One run gives 60% confidence, two give 80%, three or more give 100%. Untested levels score zero. Each task is tested on its own, and the family score is their average.
