Mute author — a NEGATIVE ranking signal
Predicted probability the viewer mutes you. Muted authors are filtered from that viewer's timeline at the socialgraph filter.
Last public weight: none — this head first appeared publicly in the 2026 release; no weight value has ever been published.
2026 weight: withheld (negative) — all current weights live in an

What actually moves it
Posting volume into the same audience raises mute risk faster than reach — see the author-diversity decay: the algorithm already discounts your Nth post.
Where it sits in the formula
Phoenix (a Grok-1-architecture transformer, phoenix/README.md)
predicts P(mute_author) per viewer from that viewer’s own
engagement history — not from your post’s running like-count. The prediction is
multiplied by its weight and summed with the other 21 terms, then the
author-diversity decay and
out-of-network multiplier apply.
