(Reuters) -Meta Platforms narrowed its annual capital expenditures forecast on Wednesday, driven by the social media giant’s high-stakes push for “superintelligence” as the artificial intelligence arms race intensifies in Silicon Valley. The Facebook and Instagram parent now expects capital expenditures to be between $66 billion and $72 billion, compared with its prior projection of $64 billion and $72 billion. After a lackluster reception for its Llama 4 model that led to staff departures, Meta has tried to revitalize its AI push by sparking a high-stakes talent war that has seen it dole out more than $100 million pay packages to researchers from rival firms.
