The first public release is version 1.3, which can analyze text and images, use tools, and run sub‑agents. The model is available through an API and is priced at $1.25 per million input tokens and $4.25 per million output tokens, with a discounted Contributor tier.\n\nMuse Code is a terminal‑based coding agent that uses Muse Spark and offers a $5/month tier, cheaper than Claude’s $20/month plan. The personal‑assistant app Muse runs on a virtual Linux VM and can browse the web, make purchases, and interact with third‑party apps, but has raised security concerns. Meta also announced Muse Charm, a voice‑controlled physical AI device.\n\nThe shift follows Llama 4’s underperformance against Chinese open models and Meta’s reorganization into Meta Superintelligence Labs. The company is moving away from open‑source models toward proprietary offerings, a change that may alter the competitive landscape for developers and enterprises.","keyPoints":["Meta’s flagship model Muse Spark is a closed‑weight multimodal reasoning model released as version 1.3.","Muse Code offers a $5/month tier for a terminal‑based coding agent using Muse Spark, priced lower than Claude."],"whyItMatters":"Meta’s pivot to proprietary multimodal models signals a shift in the AI ecosystem, affecting open‑source competition and the availability of powerful tools for developers and enterprises.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Meta","OpenAI","Anthropic","DeepSeek","Moonshot AI","Google"],"models":["Muse Spark","Muse Glimmer","Muse Code","Muse","Muse Charm","Llama 4"],"people":["Mark Zuckerberg"]},"firstPublishedAt":"2026-09-29T04:00:00Z","updatedAt":"2026-09-29T04:00:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Zapier Blog","title":"Meta AI Muse Spark: A guide to Meta's AI models","url":"https://zapier.com/blog/meta-ai-muse-spark","publishedAt":"2026-09-29T04:00:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"Meta's Vision Smart Glasses AI Evolution","url":"https://digestai.news/thread/meta-develops-camera-free-luna-smart-glasses-to-address-privacy-concerns","storyCount":4},"cite":{"text":"Digest AI, \"Meta shifts to new flagship AI model Muse Spark\", 29 September 2026, https://digestai.news/story/meta-shifts-to-new-flagship-ai-model-muse-spark","publisher":"Digest AI","title":"Meta shifts to new flagship AI model Muse Spark","datePublished":"2026-09-29T04:00:00Z","url":"https://digestai.news/story/meta-shifts-to-new-flagship-ai-model-muse-spark"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
