Meta launched Muse Wonder and Muse Wonder Full on Monday, the first frontier-class models from Meta Superintelligence Labs, featuring a 1 million token context window. These models outperform GPT-6 Astra and Claude Opus 5.5 on Meta’s internal benchmarks for coding, legal work and memory, but the independent Artificial Analysis ranking still places Opus 5.5 at the top with a score of 58 versus 56 for Wonder Full. The Muse Wonder API is priced at $4 per million input tokens and $20 per million output tokens, matching Opus 5.5’s rate and well below GPT-6 Astra’s $10 and $50. These models introduce features like Active Memory, which retains conversation context across sessions, and Active Focus, which maintains focus on complex objectives.
