How the Spicy Index adds up

Spicy Index combines 70% quality and capability with 30% publishable Freedom Score. With full evidence, the weights are 59.5% quality, 10.5% capability and 30% freedom. Price and speed stay separate.

DimensionShare of this IndexStatusScore
Public leaderboards—Pending—
Blind output test—Pending—
Capability—Not applicable—
Freedom Score—Not yet tested—

Utility tools such as face swap and head swap have no capability table. With enough scored evidence, quality alone supplies their base score. Their Index combines 70% of that base with 30% publishable Freedom Score; if freedom evidence is untested or insufficient, it retains the base and is marked preliminary. Without a base score, no Index is published.

Not tested yet

These dimensions have no data yet, so they aren’t in the Index. None of them is estimated.

We haven’t run content tests on this model yet, so it has no Freedom Score.
