Meta unveiled Muse Wonder and Muse Wonder Full on Monday, releasing its most capable artificial intelligence models to date to compete more aggressively with OpenAI and Anthropic. The social media giant’s stock rose about 4% in afternoon trading following the announcement, which follows a 14-month overhaul of the company’s AI organization led by Chief Executive Officer Mark Zuckerberg.
Meta Launches Muse Wonder Models to Challenge Competitors
Muse Wonder comes in two variants, with the more powerful Muse Wonder Full achieving 56 points in the Artificial Analysis Intelligence Index v4.3, while Muse Wonder scores 52, The Decoder reported. Their predecessor, Muse Spark 1.3, scored 48 points, according to the same outlet.
The models feature a one-million-token context window and accept text, images, video, and audio inputs, The Decoder reported. Meta highlighted two core features for the new lineup: “Active Memory,” which allows the models to recall important information across conversations, and “Active Focus,” which describes the ability to persist through difficult tasks, test alternative paths, and ask clarifying questions, The Decoder reported. These capabilities support the models’ function as personal AI agents capable of accessing calendars, messages, and documents, according to the same outlet.
Performance Gains and Pricing Details
The biggest performance jumps appear in agentic evaluations and coding tasks, The Decoder reported. Muse Wonder Full matches Claude Code with Sonnet 5.5 by scoring 68 points in the Coding Agents Index, while Muse Wonder reaches 63 points compared to the predecessor’s 54, The Decoder reported. In mathematics, Muse Wonder Full solved 94 out of 100 tasks in ProofBench, up from 58 for the previous model, The Decoder reported. However, financial and legal tasks remained flat, showing slight declines of up to two points, according to the same outlet.
Fact-knowledge remains a relative weakness, with Muse Wonder Full scoring only 30 points and Muse Wonder scoring 25 on the AA-Omniscience test, placing them behind rivals such as Claude Opus 5.5 at 46, GPT-6 Astra at 43, and Gemini 4 Argon at 42, The Decoder reported. This deficit is offset by low hallucination rates, as Muse Wonder Full reduced its rate from 33% to 23%, representing the second-lowest rate among models with at least 45 index points, according to The Decoder. Better performance comes with higher costs, with Artificial Analysis estimating Muse Wonder costs $4.52 per task in the Intelligence Index, nearly three times the price of Muse Spark, The Decoder reported.
Integration Into Personal and Developer Tools
Muse Wonder is available to developers through the Meta Model API and Muse Code, Quartz reported. Muse Wonder Full is currently restricted to Muse Code users, The Decoder reported. Meta stated that the models will soon power the subscription version of its Muse Personal AI Agent app, Quartz reported. Meta launched the personal AI agent Muse on September 8, and the app reached 5 million downloads in 22 days, outpacing ChatGPT, Grok, and Claude during the same timeframe, according to market research firm Sensor Tower cited by Quartz. The agent can send emails, book travel, fill out forms, and make purchases on behalf of a user, and it offers free use alongside subscription tiers priced at $20 and $100 per month, Quartz reported.
