Meta's latest model advances Zuckerberg's vision for personal AI assistants

Every weekday, the CNBC Investing Club with Jim Cramer releases the Homestretch — an actionable afternoon update, just in time for the last hour of trading on Wall Street. Markets are off to a mixed start to the week. The S & P 500 traded higher for most of the early afternoon, but the bulls struggled to keep the ball in the air. What held back the broader market's attempted rally was oil. WTI crude climbed 4% as markets awaited more clarity on a potential deal with Iran to open the Strait of Hormuz. Also not helping the bull's cause was data from the Department of Energy that showed the U.S. Strategic Petroleum Reserve has fallen below 300 million barrels for the first time since the 1980s. The rise in energy prices pressured bonds, pushing interest rates higher and sending the 10-year Treasury yield back to 4.70% ahead of two key inflation reports later this week. The odds of a September rate hike fell last Friday after the weak jobs report, and the market now thinks it's a coin flip between the Fed hiking rates or leaving them unchanged at its next meeting, according to the CME FedWatch tool. Meta unveiled the Muse Glimmer AI model on Monday, giving investors a glimpse into CEO Mark Zuckerberg's plans to bring artificial intelligence directly to consumers. It's also the latest release from its Meta Superintelligence Labs, the social media giant's high-dollar AI division led by Alexandr Wang. Unlike many AI systems that rely on cloud computing, Muse Glimmer is designed to run locally on personal devices including Macs and personal computers. Meta said the open-weight model is capable of agentic tasks, meaning it can perform actions and complete requests on behalf of users. An open-weight model is one whose code is publicly available for anyone to copy or modify. Meta made the model's weights publicly available through Hugging Face. "Running models locally enables you to use AI anywhere, anytime, with or without an internet connection," Meta said in a blog post. The company said it's working with partners like fellow Club names Nvidia and Intel , as well as Arm Holdings , Advanced Micro Devices , and Dell , to optimize the model's performance across a range of devices. It's worth remembering that Nvidia in June announced new PC chips for a lineup of Windows PCs set to debut later this year — precisely the kind of devices that might run an AI model like Muse Glimmer locally. Intel is a longtime juggernaut in the PC market. The launch of Muse Glimmer coincided with the release of a lengthy letter from Zuckerberg , with the CEO outlining his vision for what he called a "positive AI future" that creates a "balance of power that favors individuals." Zuckerberg argued that AI should become deeply personal, helping people accomplish daily tasks and learn news skills to navigate everyday life. Muse Glimmer fits with that strategy, positioning the AI model as a personal assistant that runs locally on computers rather than a tool accessed only through the cloud. By putting powerful AI tools into users hands, it also gives them another reason to stay inside Meta's ecosystem, from Facebook, Instagram and WhatsApp to their on-device model. In the Monday letter, Zuckerberg also called on the U.S. and its allies to "lead the open source AI ecosystem that will make up a large percent of global AI use." Muse Glimmer checks the box there. Additionally, in an Instagram video on Monday, Zuckerberg said in the coming weeks, the company plans to open the weights of Muse Spark 1.2, its latest foundation model. The Muse Spark model family was first released in April and has been closed weights since then, so Zuckerberg's update is notable. Chinese open-weight models have been a big story this summer on Wall Street and across Silicon Valley. The on-device Muse Glimmer model arrives less than a week after Meta debuted its first AI coding agent , known as Muse Code, to compete against the likes of OpenAI's Codex and Anthropic's Claude Code. Shares of Meta were fractionally higher in afternoon trading, at roughly $593 apiece. The stock has fully erased its late July sell-off on earnings, partially benefiting from the clearing event that was the forced unwind of the Situational Awareness hedge fund and Amazon CEO Andy Jassy's thoughtful defense of aggressive AI spending. While we still believe that Zuckerberg could've articulated a better AI strategy on the company's Q2 earnings call, we welcome these positive incremental updates on Monday. After the closing bell on Monday, mall owner Simon Property Group and infrastructure consultancy AECOM are set to report earnings. Before the opening bell Tuesday, we'll see earnings from Club name Cardinal Health , On Holding and Aramark . On the economic data side we'll get the NFIB small business optimism index and July existing home sales. (See here for a full list of the stocks in Jim Cramer's Charitable Trust.)
