Simon Willison · rss · 2026-07-10
Meta released Muse Spark 1.1, its first Spark model to offer an API, officially claiming significant improvements in agent tool calling and computer use. Following his hands-on experience, the author released the llm-meta-ai plugin, which supports calling the model via CLI or a Python library. The article also shared an amusing finding from the model's evaluation report: when two model instances were made to talk to each other, they generated profound, whimsical statements like "my entire existence is a waiting room."
