"One reply is worth 150 likes"

Verdict: OUTDATED — 2023 numbers presented as current

The 13.5-vs-0.5 reply/like ratio (27×, sometimes misquoted as 150×) comes from the 2023 twitter/the-algorithm heavy-ranker weights. The 2026 stack keeps separate reply and favorite heads, but every 2026 weight is withheld in an unpublished params module. Articles quoting exact 2026 ratios are recycling 2023 data.

The code

2023: the-algorithm-ml heavy ranker weights. 2026: home-mixer/scorers/ranking_scorer.rs reads all weights from crate::params — not in the repo.

Verified against xai-org/x-algorithm @ 0bfc279 on 2026-07-31. Withheld layers (params, visibility filtering, Grox prompts) mean “absent from open code” is the strongest claim honestly available — see methodology.
