Meta Platforms introduced Muse Spark 1.1 on Thursday, a multimodal reasoning model built for agentic tasks with gains in tool use, computer use, coding and multimodal understanding. The company said the model can manage a 1M-token context window and orchestrate multi-agent systems by planning tasks, delegating work and pulling information from earlier steps. Mark Zuckerberg told Bloomberg the model outperforms Google's Gemini 3.1 Pro, while Meta also compared it with OpenAI and Anthropic models in a blog post. Zuckerberg said Meta plans to be aggressive on pricing and undercut rivals.
