One of Meta's top AI researchers, Yann LeCun, is leaving after 12 years with the company to found his own AI startup, he announced. LeCun, who is also a professor at New York University, joined the company in 2013 to lead Meta's Fundamental AI Research (FAIR) lab and later took on the role of Chief AI Scientist. 

LeCun said his new startup would "continue the Advanced Machine Intelligence research program (AMI) I have been pursuing over the last several years with colleagues at FAIR, at NYU, and beyond" and that it would partner with Meta. "The goal of the startup is to bring about the next big revolution in AI: systems that understand the physical world, have persistent memory, can reason, and can plan complex action sequences," he wrote in an update on Threads. "AMI will have far-ranging applications in many sectors of the economy, some of which overlap with Meta’s commercial interests, but many of which do not. Pursuing the goal of AMI in an independent entity is a way to maximize its broad impact."

Speculation about LeCun's future at Meta has been mounting in recent months. Earlier this year, the company invested nearly $15 billion into Scale AI and made the 28-year-old CEO, Alexandr Wang, its Chief AI Officer. Meta also recruited Shengjia Zhao, who helped create GPT-4, making him Chief AI Scientist of its newly created Meta Superintelligence Labs unit. 

LeCun, on the other hand, has been openly skeptical of LLMs. "We are not going to get to human-level AI by just scaling LLMs," he said during an appearance on the Big technology podcast earlier this year. And in a recent talk at a conference, he advised aspiring researchers to "absolutely not work on LLMs," according to remarks reported by The Wall Street Journal.

At the same time, Meta has been reshuffling its AI teams. The company cut "several hundred" jobs from its Superintelligence group, including from FAIR, last month. And LeCun has "had difficulty getting resources for his projects at Meta as the company focused more intently on building models to compete with immediate threats from rivals including OpenAI, Alphabet Inc.’s Google and Anthropic," Bloomberg reported. 

LeCun said he will stay on at Meta until the end of the year. "I am extremely grateful to Mark Zuckerberg, Andrew Bosworth (Boz), Chris Cox, and Mike Schroepfer for their support of FAIR, and for their support of the AMI program over the last few years," he wrote.

YouTube has started a renewed effort to integrate direct messaging into its platform. According to a support page, the service has started testing DMs as a way for users to share and discuss videos. The test is for users aged 18 and up in Ireland and Poland. But while a DM usually comes with some expectation of privacy, Google noted that "messages may be reviewed to ensure they follow our Community Guidelines."

This isn't the video platform's first attempt to provide a messaging angle. YouTube added DMs to its app in 2017, then removed the feature in 2019 in order to emphasize public conversations in comments sections. The new test for sharing within YouTube's ecosystem won't mean any change to other ways you might send people videos. Re-introducing the same system six years after cutting it seems like an odd choice, but Google claims this is "a top feature request," so maybe it'll get a broader adoption this time around.
