Tunguz Says Meta Launched Model and Pricing System

Venture capitalist Tomasz Tunguz posted that Meta launched two items the previous day. One is a model called Muse Spark that he described as state of the art and advancing US open source models to the frontier. The other is a new pricing system for foundation models that he said resets the industry's economics. The post links to an article on X but supplies no further details on either release or any independent confirmation of the claims.
