What is Muse Wonder?

Muse Wonder and Muse Wonder Full are Meta's newest frontier AI models, released on October 12, 2026 by Meta Superintelligence Labs as the company's most capable models to date. They are built specifically for personal and professional agentic work — multistep jobs that keep changing mid-run, like booking travel, untangling an insurance claim, or building an app. Two headline abilities drive that: Active Memory, which carries relevant context across conversations and recalls it when useful, and Active Focus, which keeps the agent trying alternative approaches when it gets blocked instead of stalling and asking you what to do.

Wonder is available now through the Meta Model API and inside Muse Code, Meta's AI coding tool, while Wonder Full is reserved for Muse Code subscribers. Meta says Wonder will soon power its Muse personal AI agent, starting with subscribers. Independent scoring from Artificial Analysis puts Wonder Full at 56 on its Intelligence Index — tying Claude Sonnet 5.5 and ahead of GPT-6 Astra — though the broader field of independent benchmarks is still early, and Meta's own comparison charts come from Meta itself.

Key Features

Active Memory: remembers relevant details across conversations and pulls them back when needed
Active Focus: keeps working toward hard goals, tries alternatives when blocked, and checks in before big actions
About a 1M-token context window with text, image, video, and audio input
API access via the Meta Model API (muse-wonder-1.0) and through OpenRouter
Strong reported performance on agent tasks, coding, law, finance, and health workflows

Pros

Frontier-class agentic performance at the same API list price as Claude Opus 5.5
Independent index scores put Wonder Full alongside the best models on the market
Two access paths: a pay-per-token API for builders and Muse Code for developers

Cons

Closed weights — no downloadable model, a break from Meta's earlier open Llama era
Benchmark leadership comes from Meta's own internal tests; independent verification is still thin
The most capable variant, Wonder Full, is locked behind Muse Code subscriptions at $50–$200/mo

Pricing
