OpenAI will start watermarking ChatGPT’s text in the EU

OpenAI will start adding an invisible watermark to text generated by ChatGPT and Codex in the European Union to comply with the EU AI Act, the company said Monday in ablog post. The EU AI Act’s transparency rules, which took effect on August 2, require AI companies to mark AI-generated content in a way other systems can identify. OpenAI said the watermark will roll out over the coming weeks to eligible ChatGPT and Codex users on all plans, but only in the EU. Developers using OpenAI’s API anywhere in the world can turn it on for select models starting today; it’s off by default. OpenAI said it is not making text watermarking a global default at launch. The watermark is not an actual symbol, but works by subtly shaping the model’s word choices, leaving a pattern readers can’t see, but a detector can pick up. Because it lives in the words themselves, it travels with the text when it’s copied and pasted. OpenAI said the watermark doesn’t identify the user, and that it saw no meaningful change in its models’ performance with it switched on. OpenAI also published atechnical reportfor its method, called textGrain, alongside the announcement. Co-written with researchers from the University of Pennsylvania and Yale, it walks through an example of using a secret key to sort next-word predictions to finish the sentence. Add hundreds of these nudges together, and the detector can spot AI-generated content using only the text and the key. Can the watermark be removed by editing? OpenAI’s tests suggest yes. In one test, replacing 10% of words with synonyms dropped detection from about 92% to 66%. The company also said short passages, math answers, and translated text are harder to detect. “These limitations contribute to our decision to provide initial detector access only to approved researchers and expert organizations, who can help us evaluate reliability and responsible uses,” said the company. OpenAI also cautioned that a missing watermark “does not prove human authorship.” The text could be too short or too heavily edited, or it could come from another company’s AI. “[Watermarks] can indicate that an OpenAI system generated or processed part of a passage, but not how much human judgment, editing, or creativity went into it,” the company said. The announcement comes two months afterAnthropic said it would watermarktext generated by Claude, a move it’s applying worldwide. That decisiondrew backlash from some Claude users, who argued they had supplied “the instructions, context, decisions” while Claude was just “the tool.” OpenAI had built a text watermark before but held off on releasing it, partly over concerns that users would switch to rivals that didn’t watermark,The Wall Street Journal reportedin 2024. Anthropic, Google, Meta, Microsoft, and OpenAI are among the companies that have committed to following theEU’s code of practiceon AI-generated content.

Hot Girl Hotline is like ‘Dear Abby’ for the AI era

Hot Girl Hotline is like ‘Dear Abby’ for the AI era

Women throughout history have always sought out relationship advice, whether from newspaper columnists like “Dear Abby,” letters to Cosmo, or just chatting with girlfriends. In the social media era, you can instead post anonymously on Reddit relationship forums or look to social media creators who discuss the topic. Now, two sisters are launching a startup for young women,Hot Girl Hotline, which focuses on bringing AI into these conversations. I know what you may be thinking: With all the advances in AI technology, founders are building something for women to talk about their dating woes? Well … yes! The reality is that people have already been turning to large language models (LLMs) via apps like ChatGPT for this type of advice, and the team believes this type of activity should be handled more carefully. Unfortunately, as we’ve seen, chatting with a general-purpose chatbot about personal topics can sometimes lead to disastrous effects — especially for those who were already mentally fragile.ChatGPT, for example, has faced a wave of lawsuitsover its alleged manipulative conversation tactics that plaintiffs say contributed to negative mental health effects, including, in some cases, suicide. The idea behind Hot Girl Hotline is to reach young women who are looking to have these sorts of private conversations while navigating dating life and relationships, but in a safer way. “We’re not trying to be an AI companion,” explainedBaila Mudgil, formerly a social media consultant, who co-founded the startup with her sisterSumrin(“Sumi”), who studied computer science at Stanford. “A companion is really going after solving loneliness, escapism, boredom — and you can rely on a lot of emotional dependency from that AI companion.” Baila says the startup’s approach is to focus on offering quality advice grounded in behavioral science, but in a way that makes it feel like you’re chatting with a trusted friend or big sister. The conversation is often Socratic, with the AI asking you questions to help you arrive at the answer yourself. “This is not to replace speaking to a human. This is not clinical advice, and we have a lot of safeguards in place … we take safety really seriously,” Baila said. If conversations raise flags, for instance, the user is referred to resources such as the crisis hotline 988. “We believe the key to quality advice is not just knowing what to do next; it’s understanding why you’re doing it. So that’s a big piece of it,” added Sumi. Notably, the AI also knows when to end the conversation; it doesn’t keep asking follow-up questions to drag you further down a rabbit hole. Instead, it pushes users to go take action out in the real world rather than ruminate on the problem. The sisters believe there’s room for an app like this because not everyone wants to post on the web for advice, and there are times when you don’t want to bring up a personal, dating, or relationship-focused issue with a friend. Friends can bring their own biases into the conversation, or the user may not want to put their partner on blast for something they did before they determine whether they’re going to work through it or end the relationship. “It doesn’t mean you’re replacing your friend — you’re just trying to get another perspective,” says Baila of the hotline. The app also personalizes its advice for each user to reflect their values, goals, identity, and tastes. Under the hood, the startup relies on a mix of AI models and encrypts users’ data in transit and at rest. It doesn’t sell or train on the data, either. When it uses a third-party AI model, it follows a zero-data-retention policy there as well. Hot Girl Hotline plans to monetize through a $9.99 per month subscription, which hundreds of its most active users are already paying for. Later, it may incorporate ads, too. Relationship advice is just the beginning of how the company wants to cater to young women. It also plans to expand into other areas, like beauty and lifestyle. New York-based Hot Girl Hotline is currently bootstrapped and will be participating in theStartup Battlefield 200atTechCrunch Disrupt 2026, taking place October 13-15 in San Francisco. It’s available on iOS and the web.

TikTok rolls out an AI shopping assistant and one-click checkout

TikTok rolls out an AI shopping assistant and one-click checkout

TikTokannouncedMonday that it’s launching an AI shopping assistant and a new in-app checkout feature that lets users buy directly from brands. TikTok describes its new Shopping Assistant as a conversational AI agent designed to help users discover and purchase products. The company says the assistant understands context and remembers users’ preferences and needs throughout the conversation. It offers real-time, AI-powered shopping guidance, such as product details, shipping information, sizing, availability, and help completing a purchase. As for the new checkout feature, TikTok says users can buy directly from a brand from their For You feed (the app’s main, algorithm-driven video feed) with one click. The new features could allow TikTok to capture more of users’ shopping journeys, and potentially more transaction value, without sending them elsewhere. By pairing a shopping assistant with direct payments, TikTok is turning its impulse-driven discovery feed into a place where users can get answers to questions about a product and make a purchase on the spot. By building an AI assistant for shopping directly in its app, TikTok also appears to be hoping that users will stay within its platform when they have questions about a product, rather than turning to outside AI tools like OpenAI’s ChatGPT. The company says these new features are being built in partnership with commerce platforms and payment providers including Salesforce, Shopify, Shoplazza, and Stripe, among others. While TikTok Shop, the app’s in-house marketplace, has been the platform’s main engine for the company’s e-commerce ambitions, these new features broaden its approach beyond the existing shopping hub. Rather than relying on TikTok Shop to drive purchases, the social network is now integrating shopping tools more directly into the broader app, including the For You feed. The expansion comes as TikTok’s influence on shopping continues to grow. According toTikTok’s Economic Impact Reportthat was released last week, activity on the platform helped generate $81 billion in GDP for U.S. businesses, while 54 million Americans said they had purchased a product after watching a TikTok video. TikTok Shop launched in the U.S. in September 2023. The market research firm eMarketer estimates it generated about $15.8 billion in U.S. sales in 2025, representing roughly 18% of all U.S. social commerce.

Instinct brings its AI agent to group chats, even for friends without an account

Instinct brings its AI agent to group chats, even for friends without an account

Instinct, the AI agentnow valued at $10 billionas of its latest funding round, is expanding into group chats. The startupannouncedon Monday that users will be able to add the agent to chats with friends, which could be helpful in certain scenarios like travel planning, snagging event tickets, running fantasy leagues, organizing carpools, or managing who’s bringing what to Thanksgiving. Notably, the group chats with the AI agent will work even if a user’s friends haven’t joined Instinct, the company said. With the launch, Instinct moves ahead in its battle with top competitors in the space, like Meta’s Muse. The latter doesn’t yet offer the group chat functionality, though Meta’s older app, Meta AI, can be added to group chats on WhatsApp, Messenger, Instagram, and Facebook. Instinct in group chatsStarting today, early access users can add Instinct to group chats. A new Instinct joins and works for the whole group.Making plans with friends usually turns into a frustrating back-and-forth over times and places.

Last week, OpenAIlaunchedChatGPT Dots, personal AI agents that can also be used inChatGPT Spaces,collaborative workspaces where the Dots and humans work together. On X, Instinct founder Noah Shinnexplainedhow Instinct handles users’ privacy and security in group chats. He said a user’s personal Instinct agent will ask permission before connecting with the group’s Instinct agent, and that users can also choose which groups they trust and can remove that trust at any time. Shinn also said the group’s Instinct is siloed from the users’ personal accounts, which it cannot access. The personal agent will always ask the user’s permission before sharing information or taking any action. If new members join the group chat, any pending replies from a user’s personal Instinct agent are held before those are shared with the group, too. “Making plans with friends usually turns into a frustrating back-and-forth over times and places. With Instinct in the group, you can explore options together, agree on a plan and get it done, all in one thread,” Shinn wrote. The feature is rolling out initially to Instinct’s early access users but will expand to all users “soon.” To gain access to the new feature (or other recent additions), users can ask their Instinct agent to put them on the list to try it out.

Reflection debuts Beam, an open-weight AI model to rival Chinese models at lower compute cost

Reflection debuts Beam, an open-weight AI model to rival Chinese models at lower compute cost

Reflection AI is officially unveiling Beam, its first frontier, open-weight AI model. The two-year-old, Brooklyn-based startup claims Beam matches the performance of leading Chinese open models on advanced reasoning benchmarks at dramatically lower costs, a claim that could heat up the race to build a Western answer to DeepSeek, Qwen, and Z.ai. Reflection’s announcement confirms reporting fromAxiosover the weekend that the startup was close to a launch. The company shared new details in a lengthyblog post Monday, which described Beam as a text-only mixture-of-experts model trained on high-compute reinforcement learning to be effective at reasoning, coding, and agentic tasks at “a fraction of the token cost and inference time compute” of rivals. Beam is a 501-billion-parameter model with 23 billion active parameters. It was pretrained on 23.8 trillion tokens and has a 1 million token context window. To compare, Z.ai’s GLM-5.2 has roughly 744 billion total parameters with 40 billion active. Reflection’s performance claims haven’t been independently verified, but on advanced reasoning benchmarks, the company says Beam scores on par with Z.ai’s GLM-5.2 and outperforms today’s leading Western open models while using “3-4x less inference compute.” Reflection calls it a “workhorse model” for enterprises, the public sector, and developers. Reflection is positioning itself against closed labs like Anthropic and OpenAI, against popular open models from Chinese developers, and against Western players like Mistral, Meta, and Cohere. Its most direct U.S. rival might beInkling, the open model from Mira Murati’s Thinking Machines Lab released in July. Reflection’s own benchmarks show that Beam outscores Inkling on four coding tests where both report results, but Inkling is a multimodal model and Beam is text-only. Reflection was founded in 2024 by two former Google DeepMind researchers and hasraisedroughly $4.7 billion from backers, including Nvidia, Sequoia Capital, and Lightspeed Venture Partners, per PitchBook. Its last round valued the company at a$25 billion pre-money valuation. The startup has also been locking up compute — a key ingredient needed to train frontier models capable of luring customers away from Anthropic’s and OpenAI’s closed models, as well as the cheaper open-weight models from Chinese labs. This summer, Reflection signed deals collectively worth more than $7 billion withSpaceXandNebiusto secure access to Nvidia’s GB300 chips through 2029. Reflection is aiming Beam and future models at enterprises and sovereign nations. The pitch is to build “AI factories,” a product that would let institutions build their own customized, local AI system by training Reflection’s AI models on their own proprietary data. Nvidia CEO Jensen Huang, whose company backs Reflection, has long championed the “AI factory” idea and pushed to strengthen the open AI ecosystem — a vision that would also benefit Nvidia, whose GPUs would power those systems. Axios reported that hedge funds and trading firms are among those eager to build such systems. Reflection has already begun testing the concept of a sovereign AI factory partnership withShinsegaeGroup in South Korea. Reflection says it will release Beam’s weights and full technical details this month, with distribution through hyperscalers and neoclouds and integrations across open source libraries at launch. Reflection did not respond in time to TechCrunch’s requests for more information.
