EmbedFlow appeared on Show HN on September 9 offering zero-downtime embedding upgrades, AGPL-3.0, 43 stars on a repo created September 7. Every team running a vector store has hit the same wall, where a better embedding model ships and the corpus has to be fully re-embedded before it can be used. Pulling that out as a standalone layer is the same move as this week's other unbundlings, taking a painful operational step out of the platform that created it.
