About

Muse-Glimmer-30B (meta-models/Muse-Glimmer-30B) is Meta Superintelligence Lab's ~29.6B-parameter dense causal transformer with a dedicated Perception Encoder (~1.8B-param ViT-G/14, 50 layers, width 1536, patch 14), distilled from Muse Spark and purpose-built for autonomous agentic tasks on consumer hardware - released August 9, 2026 under Apache 2.0. Architecture: 52 layers with a [Local, Local, Local, Global] repeating attention pattern (sliding window 2048, Gated Attention, Grouped-Query Attention (GQA) 32 Q / 2 KV heads, head dim 128), hidden dimension 6656, SwiGLU FFN (19,968), RoPE (theta 500,000) on local layers only, vocabulary 202,048, up to 4,096 visual tokens per image, context length 131,072+.

It integrates end-to-end agentic task completion (DeepSearch QA, MCP-Atlas, tau3-Bench, SWE-Bench), reliable tool use, multi-step reasoning, failure recovery (diagnose-and-retry on failed tool calls), multimodal input over interleaved text and images, scaffold compatibility (OpenClaw, Hermes Agent), controllable reasoning effort, and 100+ language support. For local deployment the language model compresses to under 20GB via ~4-bit K-quantization (0.2-1.0% degradation) inside a 24-32GB envelope, and a DFlash block-diffusion drafter (5 draft layers, 16-token blocks, verified in parallel) accelerates generation up to 3.1x on an RTX 5090 with identical output quality.

Training Data Multimodal content sourced from publicly available data, data provided by third parties and information from Meta's products and services, curated and enriched by external vendor networks and Meta personnel. Knowledge cutoff: January 4, 2026.
