What happened
Mark Zuckerberg acknowledged at an internal town hall that AI agents—which Meta restructured around—have not advanced as fast as expected. The trajectory over at least the last four months hasn't accelerated the way the company anticipated, and the bets on the new structure haven't come to fruition yet.
Why it matters
Meta bet heavily on AI this year, moving roughly 7,000 employees into AI teams after a May layoff and planning to spend up to $145 billion(約23兆円) on AI infrastructure. Zuckerberg's admission signals that the company's reorganization and major talent investments have yet to deliver the efficiency gains and model breakthroughs it sought, even as competitors like OpenAI and Anthropic advance.
What to watch
Zuckerberg expects tangible results within the next three to six months. Meanwhile, AI chief Alexandr Wang countered that Meta's upcoming model code-named "Watermelon" has caught up with OpenAI's top model GPT-5.5, and that a Muse Spark update with major coding and agentic improvements is coming soon.
