Meta has introduced Muse Spark 1.1, an updated artificial intelligence model aimed at coding and agentic workflows, and is making it available to U.S. developers through a public API preview. The company said the model can handle more advanced programming tasks, including identifying and fixing complex bugs, while supporting multi-step workflows across external apps and services. Muse Spark 1.1 is also available in Thinking mode through the Meta AI app and website, and new API accounts will receive $20 in free credits.
The rollout marks a broader shift in how Meta is commercializing its AI products. The first Muse Spark model, released in April, had been limited to select partners through a private API preview. With the new launch, Meta is opening access through its own developer portal, though it is not yet distributing the model through third-party marketplaces. Meta has also disclosed pricing, with input tokens costing $1.25 per million and output tokens priced at $4.25 per million.
Meta executives are presenting the update as a more competitive offering in a market already populated by products from OpenAI and Anthropic. AI chief Alexandr Wang described the pricing as aggressive and attractive, while CEO Mark Zuckerberg called the model strong in agentic performance, tool use and computer use. The company says Muse Spark 1.1 was trained to work effectively with popular developer tools and to support large workloads such as bug fixing, workflow automation and code migrations.
The launch also underscores the pressure on Meta to show returns from its heavy spending on AI infrastructure and development. The company has been trying to catch up with OpenAI, Anthropic and Google after restructuring and high-profile hiring moves. While Meta previously emphasized open-source AI through its Llama family, it is now increasingly selling access to proprietary models, though Wang said an open-source variant of Muse Spark remains in development. The release follows Meta's launch this week of Muse Image, an image-generation model that has drawn controversy over its ability to incorporate other users' Instagram content into generated images.
