Meta has officially entered the paid enterprise artificial intelligence market, with CEO Mark Zuckerberg announcing public developer access to the company’s powerful new Muse Spark 1.1 AI model in a move that intensifies competition with industry leaders OpenAI and Anthropic.
The announcement, made by Zuckerberg in his first post on Elon Musk’s social media platform X (formerly Twitter) in three years, marks a significant shift in Meta’s AI strategy—from offering primarily free, open-source models to commercialising its most advanced artificial intelligence technology through a paid developer platform.
Describing Muse Spark 1.1 as a high-performance AI model built for software development and autonomous digital tasks, Zuckerberg said the model combines advanced coding capabilities with low-cost access for developers.
“Today we’re releasing Muse Spark 1.1 — a strong agentic and coding model at a very low price. It’s available through our new Meta Model API and in Meta AI,” Zuckerberg announced.
He said the model excels at “agentic” performance—allowing AI systems to independently complete complex digital tasks—while also offering advanced tool use, computer interaction and long-context reasoning.
According to Zuckerberg, Muse Spark 1.1 features a one-million-token context window, enabling it to process and reason over significantly larger amounts of information than many existing AI models.
He added that the system can delegate tasks to multiple AI sub-agents operating simultaneously and has been trained to interact with desktop applications, mobile devices and web browsers.
“The Meta Model API allows developers to build using Muse Spark for the first time. Our focus is on delivering strong agentic and multimodal models at very low cost,” he said.
Meta says Muse Spark 1.1 forms part of its long-term vision of developing what it describes as “personal superintelligence”—AI capable of performing sophisticated real-world tasks with minimal human intervention.
The model can write and debug software code, analyse text, images and videos simultaneously, navigate external applications and execute complex multi-step workflows autonomously.
Meta first introduced the original Muse Spark model in April through a private preview programme involving selected enterprise partners. With the latest release, the company is expanding access to developers through the newly launched Meta Model API.
Beginning Thursday, developers in the United States can access Muse Spark 1.1 through a public preview. To encourage adoption, Meta is offering new users US$20 in free trial credits before transitioning them to a pay-as-you-go pricing model.
The launch positions Meta as a direct commercial rival to leading AI firms, including OpenAI and Anthropic, which have dominated the enterprise AI market with subscription-based application programming interfaces (APIs) for developers and businesses.
With Muse Spark 1.1, Meta is seeking to attract developers by combining advanced autonomous AI capabilities with lower pricing, potentially reshaping competition in the global AI ecosystem.
