Muse Spark 1.1 is an updated version of Meta's foundation model, specifically designed for agentic and coding workloads. Released three months after the original Muse Spark.
Meta's stock surged 15% this week following the release of two AI models: Muse Spark 1.1 for agentic and coding workloads on Thursday, and Muse Image for image generation on Tuesday. The releases come three months after Meta introduced its first foundation model, Muse Spark, as the company competes with OpenAI, Anthropic, and Google.
Meta publicly released Muse Spark 1.1, a multimodal AI model designed for agentic coding workflows. The model is priced at $1.25 per million input tokens and $4.25 per million output tokens, positioning it slightly above Anthropic's Claude Haiku 4.5 and OpenAI's GPT-5.6 Luna.
Meta has released Muse Spark 1.1, the first model in the Spark series to offer API access. The company claims significant improvements in agentic tool calling and computer use compared to the original Muse Spark released in April 2026.
