How this is scored

The LoRA panel feeds the capability table’s customization row, so adding LoRA support can only raise the Index.

FLUX.1 Dev LoRA content tests, task by task

How this is scored

The 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.

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.
