**Mark Zuckerberg’s Wealth Soars $12B as Meta Posts Best Week Since 2024**
*Meta’s stock jumps after unveiling a new AI model and announcing plans for custom AI chips, driving a $12 billion jump in Zuckerberg’s net worth.*

### Introduction
Meta Platforms Inc. enjoyed its strongest weekly performance since early 2024, pushing the company’s share price up roughly 8 % and adding an estimated $12 billion to Mark Zuckerberg’s personal fortune. The rally followed two closely watched announcements: the debut of a next‑generation large‑language model and a roadmap for in‑house artificial‑intelligence silicon. Investors reacted swiftly, betting that Meta’s renewed focus on AI infrastructure could translate into higher margins and a more defensible position against rivals.

### Key Developments
On Tuesday, Meta unveiled **Llama 3**, an open‑source AI model that outperforms its predecessor on benchmark tests while requiring less computational power. The release was accompanied by a pledge to make the model freely available to developers, a move intended to broaden adoption and spur ecosystem growth.
