Meta has introduced Muse Spark 1.1, a new artificial intelligence model developed by its Alexandr Wang-led Meta Superintelligence Labs (MSL), marking the second product from that division. The company, which is planning massive capital spending on AI and reportedly exploring a cloud-computing business, has begun charging developers for access through a new fee system. According to Mark Zuckerberg, MSL’s performance has surpassed internal expectations, a statement that comes as the company competes with rivals like Google and OpenAI on benchmarks while also facing employee dissatisfaction over increased workloads tied to its AI ambitions.
