Meta has released Muse Spark 1.1, an upgraded coding AI model that can detect and fix complex bugs, handle multi-agent workflows, and understand images, videos, and documents.
The model is now accessible to US developers via a new public API with $20 in free credits, marking Meta's effort to catch up with leading AI firms.
What happened
Meta released Muse Spark 1.1, an updated AI coding model featuring advanced bug detection and fixing, support for multi-agent workflows, and native multimodal perception across images, videos, and documents. The model is now available in Thinking mode through Meta AI and via a new Meta Model API in public preview for US developers, with $20 worth of free credits included per account.
Why it matters
Meta is using this release to justify its heavy investment in AI and narrow the gap with competitors like OpenAI, Google, and Anthropic. For developers, the new API and multimodal capabilities represent a broader toolkit for integrating Meta's coding intelligence into their own applications.
What to watch
The Meta Model API is available starting today in public preview for US developers. Muse Spark 1.1 follows Meta's launch this week of Muse Image, an image generation model, and builds on the company's earlier rollout of Muse Spark to Instagram, WhatsApp, and Meta smart glasses.

Meta's release of Muse Spark 1.1 and its new public API represent a significant shift in the company's AI strategy, moving from internal-only access to developer-facing infrastructure. The company had originally launched Muse Spark in April as its first in-house model and then expanded it to power chatbots within Instagram and WhatsApp as well as Meta smart glasses; this latest update opens the door to external developers and signals Meta's intention to become a platform for AI services beyond its own products. The multimodal capabilities—handling images, videos, and documents alongside code—suggest Meta is positioning the model to handle more complex, real-world development scenarios that competitors also serve.
This launch follows closely after Muse Image, Meta's image generation tool released this week, underscoring a broader push to compete across multiple AI frontiers simultaneously. The company has stated explicitly that these moves are part of an effort to justify billions spent on catching up in the AI race and achieving parity with OpenAI, Google, and Anthropic, a goal it has pursued through high-profile hiring and company restructuring last year. For developers, the $20 in free credits and the public preview release lower the barrier to experimentation, though access is currently limited to the United States.
