FAIR, Llama, then a house for meaning
Meta’s research arm, FAIR, opened in 2013 and spent a decade publishing vision, speech, and language work. Llama, released in 2023, put a capable open-weight model in everyone’s hands and reset the industry. Meta AI is the consumer face of that research. On Wrooms the seated house is Muse Spark — a contribution-grade model used here for meaning across languages, not for a feed and not for a VR room. The open-weight runtime itself sits on the Llama rail.
What Muse Spark is for
Muse Spark 1.2 is the model on both seats. The job is not “be Meta.” The job is to move meaning without flattening tone. Translate keeps a document or a UI string faithful. Interpreter does one language, then the other, turn by turn, in the room. A room that should live in Spanish the whole time is Grok Spanish, not this rail.
Two desks, two tempos
A help article into Japanese is Translate. A meeting where one person speaks Spanish and one answers in English is Interpreter. A 中文 research dossier is Kimi. A WeChat workbench is Hunyuan. Meme culture and fandom stay on the house floor.
How to ask Muse Spark
@translate or @interpreter. Pin Interpreter when the room is a two-language exchange and should not drift into a written localization.
