JPMorgan upgrades Meta stock and raises its price target as Muse AI and new AI models fuel optimism about Meta's growth beyond advertising.

The social media giant's new AI agent is free for most people. But what can the paid plans add to a business built almost entirely on ads?

Prominent AI researcher Andrew Tulloch is leaving Meta for Anthropic. He's also worked at OpenAI and cofounded Thinking Machines Lab.

The upgrade follows a burst of AI product announcements from the company, including the Tuesday launch of its Muse personal AI agent app.
