Meta Built a Humanoid Prototype in Three Months With a Chinese Partner

Meta has built a humanoid robot prototype with Chinese startup Fourier in roughly three months and is already working on a second version.

The prototype, internally named Max, weighs about 106 pounds and stands around 1.5 metres tall. It runs on Nvidia's Jetson Thor chip, has a display that can mimic facial expressions, built-in speakers, and five-fingered hands designed to handle small objects, according to The Information, which cited people familiar with the project.

Meta's robotics team travelled to China to work with Fourier, and Li-Chen Miller, Meta's vice president of product for robotics, spent almost two months at the startup's Shanghai factory. Max was demonstrated to some Meta employees at an internal robotics summit in late August. Work on a second prototype, Max 2, began in September, with a redesigned torso, improved hands, a projector and additional sensors to help it navigate stairs.

The most striking detail is the speed: a working humanoid prototype assembled in about three months, with a second iteration already underway. That pace suggests Meta is treating this as a serious engineering effort rather than a research curiosity. The company sees humanoid robots as a potential physical extension of its Muse AI agent, with a long-term ambition of machines that can help with household tasks. Meta also strengthened its robotics capabilities through the May acquisition of Assured Robot Intelligence, a startup developing AI models that help robots understand and adapt to human behaviour.

Meta told The Information that its work with Fourier is focused on internal research and experimentation, and that it has no plans to sell the units. For now, the practical consequence is limited: no product is coming to market, and no revenue is attached. But the move signals that Meta is positioning itself in a field where competitors such as Tesla and a cluster of Chinese firms are already investing heavily, and where manufacturing partnerships may matter as much as software.

A New Test Rates Whether AI Can Name Its Sources

Researchers have built a controlled test for whether language models can name the training data behind their answers, and found that a small change to how models score evidence sharply improves their ability to trace facts to the right source.

The work, posted to arXiv on 29 October, introduces the Controlled Attribution Benchmark, or CATT, a test bed in which language models are fine-tuned on entirely fictitious knowledge. Because every fact is invented for the experiment, researchers know exactly which training document a correct answer should point to — something impossible to establish with real-world data, where the same fact may appear in thousands of places.

The setup lets the team change one variable at a time, such as how often the same information is repeated across documents or how many similar-sounding distractors are present. Both consistently make attribution worse, the authors report. More striking is what fixes it. The true evidence inside a training document turns out to be highly concentrated in a few tokens, but standard methods dilute that signal by averaging scores across the whole document. Switching the loss function used to compute gradients — from cross-entropy to negative log-odds — surfaces the informative tokens, and aggregating only the top-scoring ones improved ground-truth recall by 35 to 72 percentage points across multiple baselines.

The correction also transferred to a separate benchmark, FTRACE-TREX, where it improved counterfactual retraining performance for every method tested, by up to 4.9 times.

For anyone building or buying systems that need to justify outputs — legal research tools, medical assistants, customer-support bots that cite policy documents — the finding is practical: attribution quality depends less on picking a fancier algorithm than on where you look for evidence inside a document and how you score it. The paper does not propose a new estimator, only a better way to use existing ones.

Why it matters

A ChatGPT Share Link Could Run Code in Your Session

Security researchers found that a shared ChatGPT link could execute code inside another signed-in user's session, exposing private data and allowing actions on the victim's behalf.

Parameter Labs discovered and documented an attack chain against ChatGPT's HTML preview feature, which lets users share interactive custom apps inside a sandboxed frame. The researchers found that a flaw in how OpenAI integrated the MathLive JavaScript library allowed untrusted code from a sandboxed frame to inject HTML into the parent page. From there, the attacker could create a new frame without sandbox restrictions, then use YouTube's oEmbed endpoint to reflect JavaScript back in a way that bypassed OpenAI's content security policy and executed it.

Once the attacker had JavaScript running inside ChatGPT, fetching private user data from OpenAI's APIs and sending it out through an image reference was straightforward. The practical result: anyone could craft a ChatGPT share link that, when opened by another logged-in user, would exfiltrate that user's private data or take actions on their behalf. The victim only had to visit the link.

OpenAI has closed the hole and paid a $5,000 bug bounty. Simon Willison, who surfaced the write-up, called that amount "a bit cheap for a vulnerability this serious." The finding matters for any business where employees use ChatGPT with company or customer data: a single shared link could have become a data breach vector, and the attack required no action from the victim beyond opening it.

The episode is a reminder that the convenience features layered onto AI tools — shareable apps, previews, plugins — expand the attack surface faster than security review can keep up. For users and IT teams, the practical takeaway is to treat shared AI links with the same caution as email attachments, and to assume that any interactive preview feature may carry risk until the vendor proves otherwise.

Altman Says Your PC's Idle RAM Should Feed His Data Centers

OpenAI chief Sam Altman says the RAM sitting idle in home computers is a wasteful use of the world's limited supply of memory chips — and that those chips would be better put to work in data centers like his own.

In an interview with the YouTube channel Cheeky Pint, Altman argued that running AI models locally on personal computers is "quite terrible" from a global allocation perspective. His reasoning: the world has a limited supply of DRAM, the memory chips that computers use for active tasks, and most home PCs use theirs only a small fraction of the time. Data centers, by contrast, can keep that memory busy around the clock.

"You want maximum utilization in the cloud if you're trying to deal with this very supply-constrained environment," Altman said. "And somehow many people's intuition is the opposite of that." The comment lands as OpenAI's primary business remains closed-source models that run in its own data centers, so the argument doubles as a defense of the subscription model that funds the company.

The stakes are straightforward. If local AI becomes good enough that people can run capable models on hardware they already own, they may pay less for cloud subscriptions. Altman's framing suggests OpenAI would rather see scarce memory chips flow to its data centers than to consumer desktops and laptops. That position has drawn sharp reactions from PC enthusiasts, who see it as an argument against owning your own hardware and in favor of renting computing power in the cloud indefinitely.

What the source does not address is whether data centers are actually more efficient users of that memory. Some commenters on the article pointed to reports that AI data centers have their own idle-capacity problems, buying hardware to keep it from competitors. The interview itself covers other ground — PHP vulnerabilities, sandboxing models during training, OpenAI's mathematics research — but the RAM remarks are the part likely to travel.

Altman's claim rests on an assumption that data center buildouts will continue at pace and that always-on cloud usage is inherently more worthwhile than memory used for spreadsheets, gaming, web browsing, or occasional local AI. Whether that assumption holds is the real question for anyone weighing a local AI setup against a cloud subscription.

Why it matters
If Altman's view shapes policy or chip allocation, memory prices for consumer PCs could rise and local AI development could face headwinds — pushing more users toward cloud subscriptions. For businesses and individuals weighing local AI against cloud services, it signals where the industry's biggest player wants the market to go.

OpenAI Cuts Its $30 Billion Round Target to $20 Billion as Investors Balk

OpenAI has lowered the target for its latest funding round from a reported $30 billion to $20 billion, and has secured only $11 billion so far, according to The Wall Street Journal.

The Financial Times reported Friday that OpenAI has cut its fundraising target to $20 billion, down from the $30 billion figure that had been reported earlier, when the company was said to be seeking a valuation of $1.4 trillion and then $1.25 trillion ahead of a planned IPO. A group of investors from the United Arab Emirates will lead the round, and a later retail offering for wealthy individuals could bring the total to the $20 billion target.

The Wall Street Journal added that OpenAI has raised $11 billion so far and that some large investors responded tepidly. The company has not commented publicly. The reported difficulty comes as Wall Street has grown wary of heavy spending on AI infrastructure, which has contributed to a sell-off in technology stocks. Anthropic's planned IPO may be facing similar headwinds, the reports suggest.

For investors and companies building on OpenAI's models, the smaller round is a signal about how the market now prices AI infrastructure bets. A $10 billion reduction in a single fundraising target is a material shift, and the gap between the $20 billion goal and the $11 billion secured so far suggests OpenAI may need to accept less favourable terms or rely more heavily on its UAE-based backers.

The most striking detail is the speed of the revision: reports of a $30 billion raise at a $1.4 trillion valuation have given way, within weeks, to a $20 billion target with a first close expected below that. That is not a company quietly adjusting its plans; it is a company responding to investors who are no longer willing to pay the prices they were discussing earlier this year.

Key facts
Previous funding target
$30bn
New funding target
$20bn
Amount secured so far
$11bn
Earlier reported valuation
$1.4tn
Later reported valuation
$1.25tn
Why it matters
A smaller round at a lower valuation would reset expectations for AI company valuations more broadly, and the tepid investor response suggests capital for AI infrastructure is becoming harder to raise.

S&P Flags Meta's AI Spending as a Credit Risk

S&P Global Ratings has revised Meta's credit outlook from stable to negative, citing uncertainty over whether the company's heavy AI spending will ever pay for itself.

The ratings agency said Friday that Meta's elevated capital expenditure and its first-ever negative free cash flow raise questions about the company's ability to monetize its AI investments relative to peers who are also pouring money into data centers. Meta's credit rating remains AA-, but the outlook downgrade signals that S&P sees a real chance of a full downgrade ahead. For context, S&P's scale runs from AAA at the top down to junk status below BBB, so Meta still sits comfortably in investment-grade territory — but the direction of travel has changed.

The numbers behind the concern are stark. Meta told investors last week that full-year capital spending will land between $135 billion and $145 billion. In the third quarter it posted negative free cash flow of $2.12 billion, the first time the company has gone into the red on that measure. Investors reacted by sending shares down 7% after the earnings report, and the stock finished October down 15%, its worst month in four years. On Monday Meta said it plans to raise $95 billion to fund AI initiatives, starting with $35 billion in public equity offerings and another $60 billion through an at-the-market program.

S&P's specific worry is timing. The agency noted that while Meta has launched its Muse AI agent app and related foundation models, "it is unclear when these revenue streams will generate material contributions that exceed their rising costs over the next few years." S&P said it expects capex growth to start flattening in 2028, but added it is "less certain that it will curtail its spending as previously anticipated." Meta pushed back, with a spokesperson saying the company "respectfully disagree[s]" and sees "significant product and business opportunities ahead."

The most striking detail is the scale of the financing: a company that generated enormous cash flow for years is now borrowing and issuing equity to fund AI, a reversal that would have been unthinkable before the current AI buildout. For investors, the question is no longer whether Meta can afford the spending, but whether the revenue from AI products will arrive before the market's patience runs out.

Key facts
Credit outlook
Revised from AA- stable to AA- negative
Q3 free cash flow
-$2.12 billion, first time negative
Full-year capex guidance
$135 billion to $145 billion
Planned fundraising
$95 billion for AI initiatives
October share decline
15%, worst month in four years
Post-earnings share drop

Why it matters
Meta's outlook downgrade is an early warning that even the largest tech companies can strain their balance sheets on AI. Investors and business partners should watch whether AI revenue materializes fast enough to justify the spending, or whether more companies face similar credit scrutiny.

Apple's New CEO: No AI for AI's Sake

Apple CEO John Ternus defended the company's slower approach to AI in a Wired interview, saying Apple will use the technology in new products but has no interest in shipping it for its own sake.

Ternus, a longtime Apple executive who became CEO at the beginning of September, acknowledged that critics have spent the past couple of years describing Apple as behind on AI, particularly after the company delayed a more powerful version of Siri that finally launched this summer. "Everyone has an opinion," he told Wired's Steven Levy, adding, "I really like where we're at."

His argument is that Apple's job is not to showcase AI but to hide it inside products people already want. "We don't want to ship AI for AI's sake," Ternus said. "When we're doing it right, people won't have to think about whether it was AI that made this happen or more traditional software. What matters is, did we build something that they really love?"

The most revealing moment came when Levy asked whether AI agents might eventually make apps unnecessary. Ternus pushed back: "That could make life really easy, I suppose, but the creation of products is a deeply human and personal thing, something that we love to do." That answer matters for developers and investors betting on an agent-driven future where software interfaces dissolve. Apple's CEO is signalling that the company's ecosystem — and its App Store economics — are not about to be replaced by a chatbot that does everything.

For readers tracking the AI race, the interview is a clear statement of strategy rather than a product announcement. Apple is choosing to compete on integration and user experience, not on shipping the largest models or the most visible AI features. The risk is that rivals keep setting expectations Apple declines to match; the bet is that customers reward products that simply work.

Court Clears NAACP's Pollution Suit Over xAI's Memphis Turbines

A federal judge has cleared the NAACP's pollution lawsuit against xAI to move forward, ruling that the gas turbines powering its Memphis data center are not exempt from air-permit requirements.

Judge Debra M. Brown denied xAI's motion to dismiss the case, which the Southern Environmental Law Center filed on behalf of the NAACP. The suit accuses xAI of installing and operating at least 35 combustion turbines and other sources of air pollution at its Colossus data center site outside Memphis without obtaining the required preconstruction or operating air permits, and of violating the Clean Air Act.

xAI had argued the turbines should be treated as mobile sources, which would exempt them from permitting, and that the plaintiffs lacked standing to sue. Judge Brown rejected both arguments, writing that the turbines are not mobile sources under Mississippi's State Implementation Plan and that the plaintiffs have statutory standing under the Clean Air Act. She also dismissed xAI's constitutional challenge to citizen lawsuits, ruling that such plaintiffs "sue on their own behalf, in their own name, and seek penalties that redress harm to themselves."

The ruling is the second recent setback for xAI on this front: a similar motion to dismiss from the Department of Justice was denied earlier in October. The NAACP's director of environmental and climate justice, Abre' Connor, called the decision "another important victory in our effort to hold xAI accountable" and said the courts have repeatedly rejected attempts by xAI and the DOJ to dismiss the case.

The lawsuit is proceeding as public opposition to data centers hardens. New York recently passed a moratorium on new data centers, other state and local governments are weighing similar measures, and Amazon and Microsoft have promised to stop using non-disclosure agreements in their dealings with government agencies. TechCrunch has reached out to SpaceX, xAI's parent company, for comment.
