What happened
Meta has released Muse Spark 1.1, the first Spark model to offer an API, with reported improvements in agentic tool calling and computer use. Simon Willison has published a new plugin for the LLM CLI tool, allowing developers to easily interact with the model via command line or Python.
Why it matters
Developers and AI agent builders can now access Muse Spark 1.1 programmatically, enabling them to test and integrate its agentic capabilities into their local workflows and applications.
Discussion angle
How does Muse Spark 1.1's agentic tool calling compare to existing models, and is the LLM plugin integration seamless enough for rapid local prototyping?
