Meta open-sources Muse Spark, launches Muse Glimmer

Muse Glimmer is a roughly 30‑billion‑parameter dense multimodal (text+image) model released by Meta under an Apache‑2.0 license with open weights and single‑consumer‑GPU runtimes for Mac/PC. Engineered as a local "brain" for agentic, always‑on assistant workflows, it supports multi‑step reasoning, tool access, task diagnosis/retry, very large 128K context windows and was trained in 100+ languages. Glimmer was distilled from a larger closed Muse Spark and uses aggressive 4‑bit quantization plus a DFlash speculative‑decoding drafter to reach an on‑device footprint near ~20 GB (BF16 ~60 GB, 4‑bit ~18 GB). Meta reports >57 tokens/sec in internal tests and claims wins versus Gemma4‑31B and Qwen3.6‑27B; the model is distributed via Hugging Face and multiple runtimes/partners. Its agentic, deep‑access design raises substantial security and privacy engineering requirements. Reported by HORIZONT (2026‑08‑17), Denise Samer.

Podcast: AI roundup — Fable 5 ban, SpaceX IPO & Cursor deal

This Last Week in AI podcast episode (recorded 2026-06-17, published 2026-07-21) summarizes major AI developments: Anthropic cut off access to its Fable 5 and Mythos 5 models following a U.S. government order related to alleged jailbreaks; SpaceX completed an IPO at an approximate $1.75 trillion valuation and moved to acquire AI coding startup Cursor for $60 billion to bolster xAI; Anthropic is pursuing direct U.S. data center leases with reported financial backing from Google; leaked documents indicate OpenAI has growing revenues alongside multi-billion-dollar losses; and ChatGPT’s market share has slipped below 50% as rivals gain traction. The episode also covers technical releases and open-source model activity (OpenRouter Fusion, Moonshot, Qwen, NVIDIA), policy and legal items (DOJ arguments supporting xAI on turbines; a Munich court ruling on Google liability for false AI overviews), and several research publications.

Nonprofit Current AI builds open public AI infrastructure

Current AI, a nonprofit founded in February 2025, is building open, public AI infrastructure aimed at supporting underserved languages and communities. The group has partnered with India’s Bhashini to create Suno Sutra, an offline device that runs AI in 22 Indian languages, and recently launched an open-source chatbot called Alpha Chat developed by a coalition of organizations. Current AI allocated $3.2 million in grants to four projects across Kenya, Lebanon and the Brazilian Amazon focused on language datasets, cultural digitization, offline tools and AI auditability. Backers include the French government, Ford Foundation, MacArthur Foundation, DeepMind and Salesforce, with $400 million in total committed funding. The nonprofit also announced a collaboration with Tokyo-based startup Sakana AI to build a shared open-source AI stack supporting Japanese and Global South communities.
