The company is doubling down on AI for science.

Meta's FAIR AI team uses Brain2Qwerty v2 to translate brain activity into typed sentences, with no implants or surgery required. The system reads magnetic signals outside the skull and reconstructs what a person is typing. Clinical use for paralyzed patients is still a long way off, but accuracy keeps improving with every additional recording. AI agents that wrote their own code helped with the optimization.

Meta is building its own cloud business to sell spare AI compute to outside customers. With planned AI investments of up to $145 billion this year alone, the same question that came up with xAI now applies to Meta: why isn't the company putting all that capacity to work on its own models?

SpaceX showed investors a prototype AI smartphone that's supposedly thinner than an iPhone and integrates xAI tech. The device runs on a Qualcomm Snapdragon chip with its own operating system. Musk wants to build an "everything app" modeled after WeChat.
