Meta releases Muse Wonder, claims it beats GPT-6 Astra at one-tenth the price
Meta Superintelligence Labs' new model Muse Wonder tops GPT-6 Astra on benchmarks including personal agents and long-horizon coding, at one-tenth the price.
Today we release Muse Wonder, a strong model from Meta Superintelligence Labs. It beats GPT 6 Astra with 1/10 the price. Key features of Muse Wonder: ➤ Strong personal and professional agent performance: Muse Wonder scores 59.1 on the Personal Superintelligence Index, leading Fable 5.1 (49.9), GPT-6 Astra (54.5), and Opus 5.5 (55.2). It also ranks first on Harvey LAB-AA v1.1 (13.1), AutomationBench-AA (45.4%), and MemoryBench (85.48), demonstrating strengths in legal work, end-to-end business automation, and long-term context retention. ➤ Stronger long-horizon coding: Muse Wonder scores 79.0 on DeepSWE, ahead of GPT-6 Astra (74.1) and Opus 5.5 (74.2). On SWE-Marathon, which evaluates long-horizon software projects, Muse Wonder reaches 57.5, compared with 46.3 for Opus 5.5, 45.6 for Fable 5.1, and 42.5 for GPT-6 Astra. These results highlight Muse Wonder's advantage on complex coding tasks that require sustained execution across multiple steps. ➤ Competitive across a broad range of evaluations: Muse Wonder achieves 55.8 on the Artificial Analysis Intelligence Index, ahead of Fable 5.1 and GPT-6 Astra (both 53.0). While Opus 5.5 leads on several individual benchmarks, Muse Wonder delivers a strong combination of professional-agent capabilities, memory, and long-horizon coding performance.
