xAI's Grok 4.6 scored nearly even with OpenAI's GPT-5.6 Sol Max on the Artificial Analysis Intelligence Index, while Meta launched Muse Glimmer, a laptop-runnable open-weight model. Musk says Grok 4.7 will arrive in three to four weeks and claims it will 'exceed all current models.'

Meta released Muse Glimmer, a 30-billion parameter open-weight model under Apache 2.0 license designed to run AI agents locally on consumer hardware. It's an open version of Meta's closed Muse Spark model and supports text, images, and over 100 languages.

Meta has released Muse Glimmer, a 30-billion-parameter open-weight model under Apache 2.0, its first open release since Llama 4 in spring 2025. The launch comes with a Zuckerberg essay defending distillation of rival models and hinting at a future 'dynamic auction' pricing scheme for compute.

Meta CEO Mark Zuckerberg announced the company will open-source its Muse Spark 1.2 model and launch a new on-device model family called Muse Glimmer. The move positions Meta against closed-model rivals OpenAI and Anthropic and against Chinese open-weight labs like DeepSeek and Alibaba.

Meta has launched Muse Code, a beta terminal coding agent built on its Muse Spark model that can fan out tasks to parallel sub-agents working in isolated worktrees. The release positions Meta to compete with OpenAI's Codex and Anthropic's Claude Code, with Meta AI chief Alexandr Wang emphasizing cost advantages.

Meta has launched AI agents for businesses on WhatsApp, Instagram, and Messenger that can close sales, recommend products, and book appointments. Over one million businesses in India, Mexico, and Brazil have already signed up during testing. The feature is currently free but will move to a paid subscription in the coming months.
