Muse Wonder launch announced as closed-source frontier model family, breaking from Llama's open-weight legacy

A post by aiwaremax reports the launch of Muse Wonder, a new family of frontier models, citing an announcement from the official account. The post says independent evaluation by Artificial Analysis gives Wonder Full a score of 56, tying Claude Sonnet 5.5 and surpassing GPT-6 Astra's 53. API pricing is listed at $4/$20, in the same tier as GPT-6 Sol and Claude Opus 5.5, but the post notes Wonder Full is not available via API and is exclusive to Muse Code subscribers. The post highlights features called 'Active Memory' for cross-session long-term memory and 'Active Focus' for multi-step agent reliability, with a context window of 1 million tokens. The post emphasizes that this release is fully closed-source with no weights published, marking a complete departure from the open-source approach associated with Llama. The quoted announcement from the official account reads: 'Introducing Muse Wonder, our new family of frontier models with state of the art performance for personal and professional agentic work.'
