Meta Releases New Frontier Model, Character.AI Faces Bankruptcy Auction

The artificial intelligence landscape saw significant developments this week with Meta unveiling its new frontier model, Muse Wonder, designed for agentic and professional tasks. This model, positioned to compete with leading AI systems like Claude Fable 5.1 and GPT-6 Astra, is available via API and Muse Code, with pricing structured per million tokens. Meta also launched Muse Spark Open, an 816B-parameter open-weight model aimed at coding and agentic applications, capable of running locally on high-end hardware, though its license includes commercial limitations and attribution requirements.

In a contrasting turn of events, AI chatbot platform Character.AI has filed for Chapter 11 bankruptcy. Disney has emerged as the opening bidder in an auction for intellectual property, offering $20 million for a non-exclusive license. The platform will continue to operate during the sale process, with the auction expected to conclude by late November or early December. Meanwhile, Google has made its Gemini 4 Argon model generally available, featuring a substantial 1 million token limit for combined input and output.
