(Reuters) -Meta CEO Mark Zuckerberg has pledged hundreds of billions of dollars towards building massive data centers, days after ratcheting up the AI race with the launch of a division made up of engineers poached from rivals he hopes to challenge.

Zuckerberg has intensified Silicon Valley's talent war through aggressive hiring and startup deals, as he tries to catch up with rivals such as OpenAI, Google and Anthropic after the poor performance of the Facebook parent's Llama 4 model.
