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

The same prompts for every model, scored 1–10 by judges from different model makers who don’t see the model name. Tools are scored on their own outputs instead.
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.
We haven’t run content tests on this model yet, so it has no Freedom Score.
Measured, never scored. Price comes from the live catalogue; speed from real jobs over the last 30 days.
A time appears once at least 10 completed jobs are in. Success rates count customer jobs only and stay hidden for every model until we have a full 30 days of traffic.
SpicyAPI sells access to this model. Its scores come only from the published tables and the test records on this page. Price, commercial terms and supply arrangements play no part.
