Meta drops Muse Spark 1.3 with sharper agent and coding chops
Meta just launched Muse Spark 1.3 across Muse Code and the Meta Model API. The update tackles long-horizon agent workflows by asking clarifying questions on vague prompts, while slashing tool calls by roughly 20% and token usage by 25% during coding tasks. It also bolsters prompt-injection defenses, with open weights promised down the road.
