Meta Platforms has launched public developer access to its Muse Spark 1.1 AI model, a move that directly challenges the business models of competitors like Anthropic and OpenAI by charging for its use. The company touts Muse Spark 1.1 as its most capable model to date for coding and agentic tasks, aiming to deliver what it calls "personal superintelligence."
The upgraded model can write and debug code, utilize software and external tools, process various forms of media including text, images, and video, and perform complex multi-step tasks with reduced human oversight. This release follows Meta's debut of the initial Muse Spark model in April, which was developed by a specialized superintelligence team established to compete in the AI landscape.
Developers in the United States can now access Muse Spark 1.1 through a public preview on the Meta Model API. This allows them to test prompts, compare outputs, and develop integrations. To encourage adoption, Meta is offering $20 in free credits for API sign-ups before transitioning to a pay-as-you-go pricing structure. The model is priced at $1.25 per million input tokens and $4.25 per million output tokens, positioning it between OpenAI's entry-level GPT-5 mini and Anthropic's higher-end Claude Sonnet 4.6 model.
Muse Spark 1.1 is integrated into the Meta AI app and website in Thinking mode. It is also slated to replace the existing Llama models that currently power chatbots across Meta's platforms, including WhatsApp, Instagram, and Facebook, as well as its smart glasses. This launch comes shortly after Meta introduced Muse Image, its first image-generation model, from its Superintelligence Labs.
