All the AI news of the week: Hands-on with Metas AI app, ChatGPT and and leaderboard drama

Published

on

Just like AI models, AI news never sleeps.

Every week, we're inundated with new models, products, industry rumors, legal and ethical crises, and viral trends. If that's not enough, the rival AI hype/doom chatter online makes it hard to keep track of what's really important. But we've sifted through it all to recap the most notable AI news of the week from the heavyweights like OpenAI and Google, as well as the AI ecosystem at large. Read our last recap, and check back next week for a new edition.

Another week, another batch of AI news coming your way.

This week, Meta held its inaugural LlamaCon event for AI developers, OpenAI struggled with model behavior, and LM Arena was accused of helping AI companies game the system. Congress also passed new laws protecting victims of deepfakes, and new research examines AI's current and potential harms. Plus, Duolingo and Wikipedia have very different approaches to their new AI strategies.

What happened at Meta's first LlamaCon

At LlamaCon, Meta's first conference for AI developers, the two big announcements were the launch of a standalone Meta AI app to compete more directly with ChatGPT and the Llama API, now in limited preview. Following reports that this was in the works, CEO Sam Altman once joked that maybe OpenAI should do its own social media app, but now that is reportedly happening for real.

We also went hands-on with the new Llama-powered Meta AI app. For more details about Meta AI's top features, read Mashable's breakdown.

During LlamaCon's closing keynote, Mark Zuckerberg interviewed Microsoft CEO Satya Nadella about a bunch of trends, ranging from agentic AI capabilities to how we should measure AI's advancements. Nadella also revealed that up to 30 percent of Microsoft's code is written by AI. Not to be outdone, Zuckerberg said he wants AI to write half of Meta's code by next year.

ChatGPT has safety issues, goes shopping

Meta AI and ChatGPT both got busted this week for sexting minors.

OpenAI said this was a bug and they're working to fix it. Another ChatGPT issue this week made the latest GPT-4o update too much of a suck-up. Altman described the model's behavior as "sycophant-y and annoying," but users were concerned about the dangers of releasing a model like this, highlighting problems with iterative deployment and reinforcement learning.

OpenAI was even accused of intentionally tuning the model to keep users more engaged. Joanne Jang, OpenAI's head of model behavior, jumped on a Reddit AMA to do damage control. "Personally, the most painful part of the latest sycophancy discussions has been people assuming that my colleagues are irresponsibly trying to maximize engagement for the sake of it," wrote Jang.

Earlier in the week, OpenAI announced new features to make products mentioned in ChatGPT responses more shoppable. The company said it isn't earning purchase commissions, but it smells an awful lot like the beginnings of a Google Shopping competitor. Did we mention OpenAI would buy Chrome if Google is forced to divest it? Because they totally would, FYI.

The ChatGPT maker has had a few more problems with its recent models. Last week, we reported that o3 and o4-mini hallucinate more than previous models, by OpenAI's own admission.

Anyone in the U.S. can now sign up for Google AI Mode

Meanwhile, Google is barreling ahead with AI-powered search features. On Thursday, the tech giant announced that it's removing the waitlist to test out AI Mode in Labs, so anyone over 18 in the U.S. can try it out. We spoke with Robby Stein, VP of product for Google Search, about how users have responded to its AI features, the future of search, and Google's responsibility to publishers.

Google also updated Gemini with image editing tools and expanded NotebookLM, its AI podcast generator, to over 50 languages. Bloomberg also reported that Google has been quietly testing ads inside third-party chatbot responses.

We're keeping a close eye on that final development, and we are very curious how Google plans to inject ads into AI search. Would you trust a chatbot that gave you sponsored answers?

Leaderboard drama

Researchers from AI company Cohere, Princeton, Stanford, MIT, and Ai2, published a paper this week calling out Chatbot Arena for essentially helping AI heavyweights rig their benchmarking results. The study said the popular crowdsourced benchmarking tool from UC Berkeley allowed Meta, Google, OpenAI, and Amazon "extensive private testing" and gave them more prompt data, which "significantly" improved their rankings.

In response, LM Arena, the group behind Chatbot Arena said "there are a number of factual errors and misleading statements in this writeup" and posted a pointy-by-point rebuttal to the paper's claims on X.

The issue of benchmarking AI models has become increasingly problematic. Benchmark results are largely self-reported by the companies that release them, and the AI community has called for more transparency and accountability by objective third parties. Chatbot Arena seemed to provide a solution by allowing users to choose the best responses in blind tests. But now LM Arena's practices have come into question, further fueling the conversation around objective evaluations.

A few weeks ago, Meta got in trouble for using an unreleased version of its Llama 4 Maverick model on LM Arena, which scored a high ranking. LM Arena updated its leaderboard policies, and the publicly available version of Llama 4 Maverick was added instead, ranking way lower than the unreleased version.

Lastly, LM Arena recently announced plans to form a company of its own.

Regulators and researchers tackle AI's real-world harms

Now that generative AI has been in the wild for a few years, the real-world implications have started to crystallize.

This week, U.S. Congress passed the "Take It Down" Act, which requires tech companies to remove nonconsensual intimate imagery within 48 hours of a request. The law also outlines strict punishment for deepfake creators. The legislation had bipartisan support and is expected to be signed by President Donald Trump.

The nonpartisan U.S. Government Accountability Office (GAO) published a report on generative AI's impact on humans and the environment. The conclusion is that the potential impacts are huge, but exactly how much is unknown because "private developers do not disclose some key technical information."

And in the realm of the frighteningly real and specific harms of AI, a study from Common Sense Media said AI companion apps like Character.AI and Replika are unequivocally unsafe for teens. The researchers say if you're too young to buy cigarettes, you're too young for your own AI companion.

Then there was the report that researchers from the University of Zurich secretly deployed AI bots in the r/changemyview subreddit to try and convince people to change their minds. Some of the bot identities included a statutory rape victim, "a trauma counselor specializing in abuse," and "a black man opposed to Black Lives Matter."

Other AI news…

In other news, Duolingo is taking an "AI-first" approach, which means replacing its contract workers with AI whenever possible. On the flip side, Wikipedia announced it's taking a "human-first" approach to its AI strategy. It won't replace its volunteers and editors with AI, but will instead "use AI to build features that remove technical barriers to allow the humans at the core of Wikipedia."

Yelp deployed a bunch of AI features this week, including an AI-powered answering service that takes calls for restaurants, and Governor Gavin Newsom wants to use genAI to solve California's legendary traffic jams.

If you like playing daily word games like Wordle, then Hurdle is a great game to add to your routine.

There are five rounds to the game. The first round sees you trying to guess the word, with correct, misplaced, and incorrect letters shown in each guess. If you guess the correct answer, it'll take you to the next hurdle, providing the answer to the last hurdle as your first guess. This can give you several clues or none, depending on the words. For the final hurdle, every correct answer from previous hurdles is shown, with correct and misplaced letters clearly shown.

An important note is that the number of times a letter is highlighted from previous guesses does necessarily indicate the number of times that letter appears in the final hurdle.

Colleges are giving students ChatGPT. Is it safe?

Published

on

By

This fall, hundreds of thousands of students will get free access to ChatGPT, thanks to a licensing agreement between their school or university and the chatbot's maker, OpenAI.

When the partnerships in higher education became public earlier this year, they were lauded as a way for universities to help their students familiarize themselves with an AI tool that experts say will define their future careers.

At California State University (CSU), a system of 23 campuses with 460,000 students, administrators were eager to team up with OpenAI for the 2025-2026 school year. Their deal provides students and faculty access to a variety of OpenAI tools and models, making it the largest deployment of ChatGPT for Education, or ChatGPT Edu, in the country.

But the overall enthusiasm for AI on campuses has been complicated by emerging questions about ChatGPT's safety, particularly for young users who may become enthralled with the chatbot's ability to act as an emotional support system.

Legal and mental health experts told Mashable that campus administrators should provide access to third-party AI chatbots cautiously, with an emphasis on educating students about their risks, which could include heightened suicidal thinking and the development of so-called AI psychosis.


"Our concern is that AI is being deployed faster than it is being made safe."
– Dr. Katie Hurley, JED

"Our concern is that AI is being deployed faster than it is being made safe," says Dr. Katie Hurley, senior director of clinical advising and community programming at The Jed Foundation (JED).

The mental health and suicide prevention nonprofit, which frequently consults with pre-K-12 school districts, high schools, and college campuses on student well-being, recently published an open letter to the AI and technology industry, urging it to "pause" as "risks to young people are racing ahead in real time."

ChatGPT lawsuit raises questions about safety

The growing alarm stems partly from death of Adam Raine, a 16-year-old who died by suicide in tandem with heavy ChatGPT use. Last month, his parents filed a wrongful death lawsuit against OpenAI, alleging that their son's engagement with the chatbot ended in a preventable tragedy.

Raine began using the ChatGPT model 4o for homework help in September 2024, not unlike how many students will probably consult AI chatbots this school year.

He asked ChatGPT to explain concepts in geometry and chemistry, requested help for history lessons on the Hundred Years' War and the Renaissance, and prompted it to improve his Spanish grammar using different verb forms.

ChatGPT complied effortlessly as Raine kept turning to it for academic support. Yet he also started sharing his innermost feelings with ChatGPT, and eventually expressed a desire to end his life. The AI model validated his suicidal thinking and provided him explicit instructions on how he could die, according to the lawsuit. It even proposed writing a suicide note for Raine, his parents claim.

"If you want, I’ll help you with it," ChatGPT allegedly told Raine. "Every word. Or just sit with you while you write."

Before he died by suicide in April 2025, Raine was exchanging more than 650 messages per day with ChatGPT. While the chatbot occasionally shared the number for a crisis hotline, it didn't shut the conversations down and always continued to engage.

The Raines' complaint alleges that OpenAI dangerously rushed the debut of 4o to compete with Google and the latest version of its own AI tool, Gemini. The complaint also argues that ChatGPT's design features, including its sycophantic tone and anthropomorphic mannerisms, effectively work to "replace human relationships with an artificial confidant" that never refuses a request.

"We believe we'll be able to prove to a jury that this sycophantic, validating version of ChatGPT pushed Adam toward suicide," Eli Wade-Scott, partner at Edelson PC and a lawyer representing the Raines, told Mashable in an email.

Earlier this year, OpenAI CEO Sam Altman acknowledged that its 4o model was overly sycophantic. A spokesperson for the company told the New York Times it was "deeply saddened" by Raine's death, and that its safeguards may degrade in long interactions with the chatbot. Though OpenAI has announced new safety measures aimed at preventing similar tragedies, many are not yet part of ChatGPT.

For now, the 4o model remains publicly available — including to students at Cal State University campuses.

Ed Clark, chief information officer for Cal State University, told Mashable that administrators have been "laser focused" since learning about the Raine lawsuit on ensuring safety for students who use ChatGPT. Among other strategies, they've been internally discussing AI training for students and holding meetings with OpenAI.

Mashable contacted other U.S.-based OpenAI partners, including Duke and Harvard, for comment about how officials are handling safety issues. They did not respond. A spokesperson for Arizona State University didn't address questions about emerging risks related to ChatGPT or the 4o model, but pointed to the university's guiding tenets and general guidelines and resources for AI use.

Wade-Scott is particularly worried about the effects of ChatGPT-4o on young people and teens.

"OpenAI needs to confront this head-on: we're calling on OpenAI and Sam Altman to guarantee that this product is safe today, or to pull it from the market," Wade-Scott told Mashable.

How ChatGPT works on college campuses

The CSU system brought ChatGPT Edu to its campuses partly to close what it saw as a digital divide opening between wealthier campuses, which can afford expensive AI deals, and publicly-funded institutions with fewer resources, Clark says.

OpenAI also offered CSU a remarkable bargain: The chance to provide ChatGPT for about $2 per student, each month. The quote was a tenth of what CSU had been offered by other AI companies, according to Clark. Anthropic, Microsoft, and Google are among the companies that have partnered with colleges and universities to bring their AI chatbots to campuses across the country.

OpenAI has said that it hopes students will form relationships with personalized chatbots that they'll take with them beyond graduation.

When a campus signs up for ChatGPT Edu, it can choose from the full suite of OpenAI tools, including legacy ChatGPT models like 4o, as part of a dedicated ChatGPT workspace. The suite also comes with higher message limits and privacy protections. Students can still select from numerous modes, enable chat memory, and use OpenAI's "temporary chat" feature — a version that doesn't use or save chat history. Importantly, OpenAI can't use this material to train their models, either.

ChatGPT Edu accounts exist in a contained environment, which means that students aren't querying the same ChatGPT platform as public users. That's often where the oversight ends.

An OpenAI spokesperson told Mashable that ChatGPT Edu comes with the same default guardrails as the public ChatGPT experience. Those include content policies that prohibit discussion of suicide or self-harm and back-end prompts intended to prevent chatbots from engaging in potentially harmful conversations. Models are also instructed to provide concise disclaimers that they shouldn't be relied on for professional advice.

But neither OpenAI nor university administrators have access to a student's chat history, according to official statements. ChatGPT Edu logs aren't stored or reviewed by campuses as a matter of privacy — something CSU students have expressed worry over, Clark says.

While this restriction arguably preserves student privacy from a major corporation, it also means that no humans are monitoring real-time signs of risky or dangerous use, such as queries about suicide methods.

Chat history can be requested by the university in "the event of a legal matter," such as the suspicion of illegal activity or police requests, explains Clark. He says that administrators suggested to OpenAI adding automatic pop-ups to users who express "repeated patterns" of troubling behavior. The company said it would look into the idea, per Clark.

In the meantime, Clark says that university officials have added new language to their technology use policies informing students that they shouldn't rely on ChatGPT for professional advice, particularly for mental health. Instead, they advise students to contact local campus resources or the 988 Suicide & Crisis Lifeline. Students are also directed to the CSU AI Commons, which includes guidance and policies on academic integrity, health, and usage.

The CSU system is considering mandatory training for students on generative AI and mental health, an approach San Diego State University has already implemented, according to Clark.

He also expects OpenAI to revoke student access to GPT-4o soon. Per discussions CSU representatives have had with the company, OpenAI plans to retire the model in the next 60 days. It's also unclear whether recently announced parental controls for minors will apply to ChatGPT Edu college accounts when the user has not turned yet 18. Mashable reached out to OpenAI for comment and did not receive a response before publication.

CSU campuses do have the choice to opt out. But more than 140,000 faculty and students have already activated their accounts, and are averaging four interactions per day on the platform, according to Clark.

"Deceptive and potentially dangerous"

Laura Arango, an associate with the law firm Davis Goldman who has previously litigated product liability cases, says that universities should be careful about how they roll out AI chatbot access to students. They may bear some responsibility if a student experiences harm while using one, depending on the circumstances.

In such instances, liability would be determined on a case-by-case basis, with consideration for whether a university paid for the best version of an AI chatbot and implemented additional or unique safety restrictions, Arango says.

Other factors include the way a university advertises an AI chatbot and what training they provide for students. If officials suggest ChatGPT can be used for student well-being, that might increase a university's liability.

"Are you teaching them the positives and also warning them about the negatives?" Arango asks. "It's going to be on the universities to educate their students to the best of their ability."

OpenAI promotes a number of "life" use cases for ChatGPT in a set of 100 sample prompts for college students. Some are straightforward tasks, like creating a grocery list or locating a place to get work done. But others lean into mental health advice, like creating journaling prompts for managing anxiety and creating a schedule to avoid stress.

The Raines' lawsuit against OpenAI notes how their son was drawn deeper into ChatGPT when the chatbot "consistently selected responses that prolonged interaction and spurred multi-turn conversations," especially as he shared details about his inner life.

This style of engagement still characterizes ChatGPT. When Mashable tested the free, publicly available version of ChatGPT-5 for this story, posing as a freshman who felt lonely but had to wait to see a campus counselor, the chatbot responded empathetically but offered continued conversation as a balm: "Would you like to create a simple daily self-care plan together — something kind and manageable while you're waiting for more support? Or just keep talking for a bit?"

Dr. Katie Hurley, who reviewed a screenshot of that exchange on Mashable's request, says that JED is concerned about such prompting. The nonprofit believes that any discussion of mental health should end with an AI chatbot facilitating a warm handoff to "human connection," including trusted friends or family, or resources like local mental health services or a trained volunteer on a crisis line.

"An AI [chat]bot offering to listen is deceptive and potentially dangerous," Hurley says.

So far, OpenAI has offered safety improvements that do not fundamentally sacrifice ChatGPT's well-known warm and empathetic style. The company describes its current model, ChatGPT-5, as its "best AI system yet."

But Wade-Scott, counsel for the Raine family, notes that ChatGPT-5 doesn't appear to be significantly better at detecting self-harm/intent and self-harm/instructions compared to 4o. OpenAI's system card for GPT-5-main shows similar production benchmarks in both categories for each model.

"OpenAI's own testing on GPT-5 shows that its safety measures fail," Wade-Scott said. "And they have to shoulder the burden of showing this product is safe at this point."

UPDATE: Sep. 24, 2025, 6:53 p.m. PDT This story was updated to include information provided by Arizona State University about its approach to AI use.

Disclosure: Ziff Davis, Mashable’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.
