      "community_discussion_en": "The Hacker News thread drew roughly 184 points and 25 comments, with practitioners such as simonw and minimaxir broadly positive: the Apache 2.0 license and multimodal capability were praised, with minimaxir saying the lack of a good moderate-size embedding model had been an annoyance. The main caveat raised was the MRL-versus-MatFormers training choice, which prevents shrinking weights with lower-dimensional embeddings.",
