AI NewsHow AI decision models could change content moderation

How AI decision models could change content moderation

3:00 AM IST · October 7, 2026

As decision models spread across the industry, a company called Musubi has a new idea for how to put them to work: moderating content. On Tuesday, Musubi announced a lightweight decision model made for real-time moderationcalled PolicyLM-1.7B, released with open weights. The idea is to take a content policy written in plain English and apply it to messages in under 50 milliseconds. Musubi’s model is designed to be similar in cost and speed to the AI classifier systems that power moderation on most social platforms — but because it has the flexibility of a modern LLM, it can apply complex policies without special training. Even more important, the model won’t need new training when the policy changes, allowing for human policy-setters to iterate as much as they need. As Musubi co-founder and chief AI officer Filip Jankovic sees it, it gives platform managers a way to label content proactively. “Product teams just want a better understanding of what’s happening on their platform, especially as the amount of content is exponentially increasing,” Jankovic says. “Being able to label all of that in a very scalable, customizable way is extremely useful.” Decision models have become a hot topic in the AI world sincethe release of TypeSafe AI’s Jev in September, which was shortly followed by competing decision models fromOpenAIandAmazon. Instead of outputting text, a decision model outputs outcome probabilities, though in this case the model outputs a binary judgement: Either the content is in the category or it isn’t. By limiting the model’s output to a set of predetermined choices, decision models are able to run faster and cheaper than large language models, while still maintaining the flexibility of the transformer architecture. One early use case is reining in misbehavior by AI agents — so it’s only natural to apply the same technology to human misbehavior. Notably, Jankovic says his interest in decision models predates Jev, tracing it back toa 2024 project called GLiNER(Generalist Model for Named Entity Recognition) that deployed many of the same techniques. Still, Musubi isn’t wary of the comparison. If anything, the company is eager to use the new interest in decision models to shine a light on content moderation. “If Jev caught your eye, PolicyLM-1.7B is the same kind of model, trained specifically for content moderation, that you can run yourself,” the product announcement reads.

Hark releases an AI personal assistant with a focus on privacy

From Muse to Instinct to Dots, tech firms are hunting for the user experience that will make an AI personal assistant a must-have product. Hark, a startup founded less than a year ago by serial founder Brett Adcock, is throwing its hat in the ring today with the wide release of Hark Pro. Users can access the service for free, with a subscription tier for heavy users. The company sees its mission as building a user interface for AI, not creating AGI or curing cancer. The foundation is a model trained specifically for computer use, and that’s what Hark Pro does — it uses your computer for you. That’s perhaps a less ambitious claim than some frontier labs are making, but a little humility goes a long way in winning over users. And rather than an app, Hark’s goal is to create an operating system for the AI computers of our future. Hark Pro is a full-screen experience with a kind of homepage, featuring a central chat dialog and a feed populated by prompts for actions you might need it to take and visualizations the company calls “panels” that offer mini-dashboards for things you’re interested in. The background is a piece of custom imagery tailored to the weather and time where you are. Like other AI assistants, users configure it to access their digital life — email, calendar, hard drive, credit cards, etc. Then, it can take on digital tasks as well as fielding classic chatbot questions. Abidur Chowdhury, a former Apple staffer who leads design at Hark, demoed the product for me. It proactively asked him about expenses he needed to approve, emails he needed to respond to, a meeting with this reporter, and, of course, pointed out that he needed to book a flight for a trip and offered to take care of it. (“I know the flight thing is put to death,” he admits, grinning.) That does get at the challenge with these apps: One of the harder things for users is actually coming up with useful tasks they are capable of accomplishing. Chowdhury says he was impressed when the AI assistant recently recognized that one of his colleagues needed to renew their car registration at the California DMV, and handled it through the agency’s website. One notable UX choice that Hark makes is showing the user how the agent navigates the web in a small window, an action most AI assistants perform without it surfacing in the app, which Chowdhury says is intended to build trust with users that the agent is doing the right thing. That matters because part of Hark’s pitch is that they are not Meta or OpenAI — “we’re not here to like sell you ads and steal your data,” Chowdhury says. To truly leverage these models, users will need to share their entire digital lives. Beyond very realcybersecurity concerns, will users be comfortable with a company like Meta having its productscreate detailed profilesof their friends and family? Asked about that kind of profiling, Chowdhury says that “we are doing work to understand you, and be helpful for what you need, but it’s really like task-related — it’s really about how Hark can help take something off your plate and be useful.” What sets Hark Pro apart from its competitors, Chowdhury says, is its effort to fully subsitute for your computer, but also his belief that it just works better. “Please compare it to the others, be critical,” he says. “It might not be faster than Muse, but it will give you a better result, and it will work end-to-end instead of asking you to take over at a point.” One open question is what kind of model best suits the AI personal assistant. Hark’s is explicitly trained for computer use, which makes it faster and cheaper at those tasks, but it’s not clear how much it is trading away the broader knowledge and capability of a frontier LLM. This software is only half the promise of Hark; Chowdhury made his name designing devices at Apple and Hark promises to release an AI-native device to support its software in 2027. They’re still cagey about the form it will take, with Chowdhury bemoaning the “creep factor” of wearable cameras. “I will give you this: The first product that we’re building is a product that’s never ever existed before,” he says. We’ll have to wait and see if this is mere hype and Hark puts out some retread tech instead of a truly novel product. “It’s so hilarious to me that you have AI now, you have a chatbot, and you type stuff in with a keyboard,” Chowdhury says. “Fifty years later and the future of computing is still a terminal.”

The next hurdle for AI agents: getting websites to let them in

Personal AI agents, like Meta’s Muse, Instinct, ChatGPT’s Dots, and others, are kicking off a new wave of consumer AI that involves more than just responding to queries. These AI agents can actually get things done on users’ behalf, like booking flights, making dinner reservations, ordering groceries, and more, all without having to be technical enough to set up OpenClaw or some other agent on your own computer. But consumers adopting these agents are often running into issues when the website on the other end of their request blocks the AI from completing the job. Most recently,Amazon began blocking Meta’s Muse AI agentfrom its retail site, meaning that the agent could no longer browse or make purchases from its product catalog. However, the problem is not limited to Amazon or Muse. User complaints across social media indicate their agents are often running into similar blocks. Some of these are intentional, like Amazon’s, while others are the result of websites’ traditional anti-bot measures designed to protect against spam and malicious activity. What’s not clear to the end user is whether or not the block is accidental on the website owner’s part, which leaves them frustrated with both the service provider or retailer and the agent trying to facilitate the transaction. For instance, TechCrunch has seen ahandfulofcomplaintson social media claiming that Muse couldn’t complete a purchase on Walmart’s retail website. (NBC also reportedthat this was a problem Walmart had faced in its tests of the AI agent.) But a spokesperson for Walmart told us these weren’t intentional. In fact, Walmart is partnered with Muse, as wasannounced at Meta’s Connect developer conferencein September. The company said it wants to be where its customers are, and that now includes being available through AI agent experiences. The issue that Walmart customers often appear to be running into (see below) is that the website presents a button that has to be clicked to verify the visitor is human. If that experience is interrupted, the check could fail, and the agent gets booted out. It’s an indication that the current technology we use to verify humans and keep websites safe from spam and bots may not be the best fit for the agent-first era of the web we’re now moving into. To address this problem, industry partners including Meta, Walmart, Stripe, Sierra, Genesys, Rocket, NiCE, and Decagon have begunworking on an open standardthat would dictate how AI agents can communicate with businesses, helping to separate the good bots acting on behalf of the user and the bad. This protocol will be specifically focused on agent-to-agent communication for the purposes of online commerce, Meta said in ablog post. This is frustrating.@Walmartin their attempt to stop agent from making purchases has gone too far and is essentially blocking actual human from making purchase on their website. I tried to purchase something directly and I can't even sign in.pic.twitter.com/CRAgkrCCa0 In the meantime, consumer confusion abounds. Although Walmart is at least trying to be accessible via AI agents, other companies aren’t so keen on the idea or haven’t fully embraced the technology. For example, flight booking is currently one of the main use cases being positioned for agents, but many people have reported issues with airlines rejecting their agents’ requests. Delta, for instance, told us that the company is taking steps to protect customers from unauthorized automated activity, and that if it were to open up to AI agents, it would have to be done with “security and the customer experience in mind.” “While Delta does not currently have a partnership or integration that enables a third-party AI agent to shop for or book Delta flights on a customer’s behalf on our digital platforms, we’re continuing to evaluate how new technology, including external AI agents, could enhance the way customers engage with Delta,” said Delta’s general manager of Global Communications, Heena Chavda, in response to our questions about whether or not it was blocking agents, as some users complained. United was not quite as direct as Delta, but a spokesperson pointed us to the part of its Terms of Use policy, which says that the user agrees “not to use any robot, spider, other automatic device, or manual process to monitor or copy this website or the content contained therein or for any other unauthorized purpose without United’s prior written permission.” (United didn’t respond to a follow-up question about whether it was blocking specific personal AI agents, like Muse.) Early adopters’complaintsacrosssocialmediahave referenced a number of brands that are reportedlyblockingAI agents,includingYelp,eBay,Zillow,Pizza Hut,Adidas,andvariousairlines. Some believe that the blocking activity seems to have recentlyincreased. A couple of people even said eBaysuspendedtheiraccountsbecause of their use of agentic AI. Another complained thatGoogle kicked out Instinctwhile it was cleaning up their Gmail inbox for them. Looks like@adidaswon't get my business tonight 😪pic.twitter.com/DXcPYE5S6O Despite the push to have agents book tables at restaurants and other tedious tasks, Yelp told us that it doesn’t permit non-human traffic on its platform unless the agent has paid to access Yelp’s content and data through itsdata licensing program. That means agents trying to use its site to get a quote, add a user to a waitlist, or book them a table will likely fail if they don’t have a formal partnership with Yelp. eBay told TechCrunch that its approach is not to prohibit all third-party shopping agents from completing purchases. Instead, its policies restrict unauthorized agents and actions, like automated scraping and model training. Adidas, Zillow, and Pizza Hut either didn’t respond or declined to provide a comment by the time of publication. One major company involved in this space is Cloudflare, which offers sites protection from AI agents that could be training on its data and managing other automated activity. SomesuspectthatCloudflare and other content delivery networks (CDNs) like it are currently disrupting Muse traffic. This isattributedto a change to crawler defaults on September 15, which allows site owners to block AI training while allowing other types of bots. Existing sites that were previously set to block AI bots for security reasons were then shifted to block AI agents on any pages that had ads. However, when we asked if Cloudflare had any insight into what was happening with the blocking of these personal AI agents, like Muse and others, the company said it didn’t have any specific data to share at this time. It pointed us instead to its free public data hub,Cloudflare Radar. The site shows the increase in bot activity (which Cloudflare has also commented on previously), but it doesn’t help differentiate between the good bots and the bad ones. Cloudflare also has a vested interest in mitigating AI traffic to websites, as itnow runs a marketplacewhere AI bots have to pay for the data they access. It recently began testinga new web browser built specifically for AI agents. Given the rapidly evolving space, Meta’s decision to form specific brand partnerships for Muse access seems to be the right way to go, as is its decision to focus on new standards. In doing so, it assures its customers that its agent, at least, is welcome at these partners’ sites — so any issues with access would be reportable bugs. Meta also maintains a list of “connectors” (a.k.a. partners) inside the Muse app, which continues to grow. Many of Meta’snewly announced partnershaven’t yet shown up in this list. But given Muse’s rapidexpansion, which now includespartnered tools for small businesses, a bigger reorganization of Muse’s connector list is likely soon to be underway. “Turning away a personal agent means turning away the customer behind it. We’d rather work with businesses to address the underlying concerns than see them lose that customer,” Meta said in its announcement about the newly announced plans to develop a standard. “There is a path that is good for users and good for businesses. It starts with clear norms, gives businesses more predictable control, and evolves toward a more efficient way for agents to work together.”

AI computing startup Lambda to raise $4B ahead of planned IPO

Cloud provider Lambda is raising up to $4 billion at a $14.5 billion pre-money valuation, marking what could be its last private round before a planned 2027 IPO, according toThe Wall Street Journal.Coatue Management and Blackstone are leading the round. A letter to investors reviewed by the Journal shows Lambda’s backlog grew from $15 billion in June to $50 billion in September. While that might look like a hearty increase in demand, much of that increase appears to be driven by a$35 billion commitmentfrom one company: Anthropic, which signed a deal with Lambda in late August. That means Lambda’s valuation, which has climbed significantly since its2025 funding round, could be leaning heavily on Anthropic’s ability to keep paying. Still, with reliable GPU capacity so scarce, investors are clearly still willing to bet on companies that provide it, especially ones with large contracts with a major AI lab. For neoclouds like Lambda, demand isn’t so much the problem as is the cost of meeting it. Data center buildouts are largelyfunded by debt— of which Lambda just raised anadditional $1 billionlast week — andlenders are getting choosierabout who they offer cash to and under what circumstances. Lambda’s decision to raise more now not only sets the tone for its IPO pricing, but also gives it access to more capital before the scrutiny of public markets arrives. If and when Lambda does IPO — the company wasreportedlymeant to debut this year, but has pushed that back amid market uncertainty — it will join other Nvidia-backed neoclouds, likeCoreWeaveandNebius, that now depend on the health of their stock to fund their data center buildouts. British neocloudNscalefiled for an IPO last month and is expected to begin trading soon. Lambda, Coatue, and Blackstone did not immediately respond to a request for comment.
