# Meta — Muse Glimmer

> AI lab announcements, news reports and podcasts.

forck.live follows what companies announce about their own products. Press may
corroborate an official story; it never leads and never appears as an item of its
own. A missing date stays missing. A title is the publisher's words — where a
company does not publish in English, an English rendering is listed separately
as `Title in English` and named as this site's translation, never as theirs.

This file is the record of one model version: what the model registry states
about it, Meta's launch post, the first-party posts this record
holds about it, the outlets that reported on those posts, and other companies'
announcements that it runs on their platforms. A model ranks nothing here and
nothing is composed: each date names whose it is, and a field nothing states is
`not stated` rather than missing.

## Posts about it

_Meta's own posts whose title names Muse Glimmer, and its launch post, in the record's order: dated newest first, undated last. The record reads the newest 50 first-party posts mentioning the model, every company's together, so a model mentioned more often than that lists the newest of them._

Every entry is one first-party announcement, and carries the same eight fields
in this order before any others:

    Company · Announced · Category · Coverage · Announcement · Group · Source · Record

`Source` is the company's own page the announcement was traced to and `Record`
is this site's page for it. Both are safe to cite.

`Coverage` is a number of outlets, or `not counted` — which means this record
reached no count of its own, never that nobody wrote about it.

`Category` is this tracker's own analysis, and is authoritative wherever it is
stated. `not stated` means either that nothing has analysed the post yet or
that the analysis placed it outside this taxonomy; neither is a verdict about
the announcement.

`Announcement` is whether the post is news of something the company did, rather
than a how-to, a customer story, a changelog listing or a staffing note.

`Group` is which of this record's groups the entry falls in, carried on the
entry itself so it holds where the groups are headings and where they are not.
One of: `models`, `covered`, `announcements`, `routine`.

Anything after `Record` is held detail that only some announcements carry.

### Hugging Face — Welcome Muse Spark Open: open-weight frontier multimodal mixture-of-experts model from Meta

- Company: Hugging Face (huggingface.co)
- Announced: 2026-10-15
- Category: open-weight-release
- Coverage: not counted
- Announcement: yes
- Group: models
- Source: https://huggingface.co/blog/meta-muse-spark-open
- Record: https://forck.live/items/23000-welcome-muse-spark-open-open-weight-frontier-multimodal-mixture-of-experts
- Subject: Platform

Meta released Muse Spark Open, an open-weight multimodal mixture-of-experts model with approximately 816 billion total parameters and about 42 billion active per token, supporting text, images, audio, and video input. The model is optimized for agentic coding tasks such as reading codebases, writing and debugging code, and calling tools, and can also process screenshots, voice notes, and screen recordings. It uses 256 experts per MoE block with 8 selected per token, and offers a context window of up to one million tokens. The BF16 checkpoint requires 4 nodes of 8 H200 GPUs, while an NVFP4 checkpoint runs on a single B200 node with negligible accuracy loss.

### Hugging Face — Meta is back with Muse Glimmer: local, agentic, multimodal, and open source

- Record: https://forck.live/items/3747-meta-is-back-with-muse-glimmer-local-agentic-multimodal-and-open-source
- Subject: Platform

Meta released Muse Glimmer, a 30B parameter multimodal model distilled from Muse, licensed under Apache 2.0, designed for local agentic use cases like coding, document analysis, and personal assistants. It includes a 2B vision encoder and a 28B text decoder with hybrid attention and Gated Grouped-Query Attention. Support for transformers, llama.cpp, vLLM, and Inference Endpoints is provided day-0. Benchmarks show competitive performance in agentic and multimodal tasks against models like Gemma4-31B and Qwen3.6-27B.
