Meta is launching a cloud business to sell its spare AI computing power to outside customers, following a similar strategy used by SpaceX. This move allows Meta to monetize its excess computing capacity, which was initially purchased to support its own AI model development. By doing so, Meta can offset the massive costs of its AI infrastructure spending, which is expected to reach $145 billion this year. The company may also offer access to its AI models on its infrastructure, providing additional revenue streams. Why it matters: this development signals a significant shift in the AI landscape, where companies are now exploring alternative ways to utilize their computing resources and generate revenue beyond their core business models.
