RT by @ylecun: 1/ big announcement today: we will be releasing an open weight version of muse spark…

TL;DR - A retweeted product announcement (thread opener) stating that Muse Spark 1.2 will get an open-weight release and that Muse Glimmer, a 30B agentic model, is being released under Apache 2.0. It matters as another push toward permissively licensed agentic models that run on consumer-class hardware.

• Muse Spark 1.2: an open-weight version is promised "soon"; no date, benchmarks, or license stated in the excerpt.
• Muse Glimmer: 30B parameters, positioned as an "agentic" model, released with open weights under Apache 2.0 (commercially permissive).
• Claimed deployment target is 24GB VRAM (single high-end consumer GPU) "without losing agentic reliability" — implies quantization/compression, though no method or eval is given.
• Content is thin: this is only tweet 1 of a thread, so all claims are vendor-stated and unverified here.
