Meta releases Muse Wonder and Muse Wonder Full AI models, stock up more than 3%

Meta released two AI models, Muse Wonder and Muse Wonder Full, on 12 October 2026. MarketWatch reported the company's stock was up more than 3% following the release. MarketWatch also reported that analysts expect the models to drive new business opportunities.

Meta says the models compete with the industry's best and will soon power its Muse agent, according to The Verge. The company says internal testing on several industry benchmarks shows the models can rival leading models from OpenAI and Anthropic, including GPT-6 Astra, Claude Opus 5.5 and Claude Fable 5.1.

The Verge reported it is unclear how the new models compare with Google's Gemini 4 Argon, whose capabilities are still coming into focus. Meta's claims about rivalling other companies' models are based on its own internal testing, according to The Verge.

The Verge described the launches as part of Meta's push to reestablish itself as a major force in AI. The Verge reported the company has poured billions into talent and infrastructure and has been expanding its AI lineup, which includes the image model Muse Image. Earlier releases included Muse Spark, the first model from Meta's revamped Superintelligence Labs division, and the Muse AI agent, according to The Verge.
