Notes on facebookresearch/faiss

How many stars does facebookresearch/faiss have?

What does recent star activity look like for faiss?
gitdebt observed about 11 public star actions for facebookresearch/faiss over the latest 90 days of archive coverage (about 11 in the latest 30). This is an approximate attention signal, not a net-star count, because unstars are not present. That's below its lifetime average activity pace, which is common for mature projects.

Light and dark variants, alt text, and one provenance line. Provenance is text in your README, never baked into the image URL, so the chart stays cacheable.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
