Meta launched Muse Glimmer, a 30-billion-parameter open-weight AI model that runs locally on consumer hardware, and called for US regulatory reforms to reduce barriers on open-source AI development. The company also announced a $1 billion fund to support communities near its data centres amid its planned $145 billion AI infrastructure spend in 2026.
