Meta unveils Muse Spark 1.3 to boost coding and personal-agent tasks
Meta released Muse Spark 1.3, claiming faster coding and stronger agentic performance to advance its 24/7 personal-agent vision. The update—priced the same as the prior version— arrives amid rival model launches from Google, OpenAI, and Anthropic, and it includes a lower-cost 'contributor tier' for developers who share work to improve the models. Muse Spark 1.3 rolls out in Muse Code and via API, with a max-reasoning version to follow after safety testing; Meta says it’s stepped up safety and alignment investments as it continues moving ahead.
