It's been clear for a while now that the default ChatGPT experience is designed to nod along with most of what you say. But even that tendency can go too far, apparently. In a thread on X posted on April 27, OpenAI CEO Sam Altman acknowledged that "GPT-4o updates have made the personality too sycophant-y and annoying." And today, Altman announced on X that the company was fully rolling back the 4o update for paid and free users alike. But users have started complaining online about the 4o model's overly agreeable personality.

As of Monday, April 28, OpenAI is experimenting with new ways to recommend products to ChatGPT users. OpenAI announced the update on Monday, saying the ChatGPT search tool will now make it "simpler and faster to find, compare, and buy products in ChatGPT." In a post on X, OpenAI said that the AI chatbot can now show product images, comparisons, pricing, reviews, and even a direct link to various retailers. Mashable was able to generate the new features using the ChatGPT 4o model. The new "shopping improvements" make ChatGPT a stronger competitor to Google's search product, which searchers often use to find product recommendations.

In the thick of Meta's first-ever AI developer conference, LlamaCon, CEO Mark Zuckerberg hit the launch button on Meta AI -- the company's full-throttle answer to OpenAI's ChatGPT. According to Meta's April 29 press release, the new standalone AI app is built on the company's latest Llama 4 model. It's pitched as a hyper-personalized assistant for users already living inside the Meta ecosystem: WhatsApp, Instagram, Facebook -- you know the drill. In a choice Instagram video, Zuckerberg, framed in a pair of Meta Ray-Ban glasses, pitched the app as a product built for voice-first conversations. One standout feature is the Discover feed.

Maybe you've noticed: Siri doesn't quite sound like Siri anymore. However, it's just enough to make you pause and ask, "Hey, Siri, did your voice change?" Occasionally, Google search trends light up with people wondering whether Siri's voice is different -- or, rather, whether the voice assistant's many voices are different. Across the internet, users are reporting that Siri's voice has turned flat, unnatural, stern, and oddly disengaged. Gone is the upbeat, more conversational tone we're used to.

OpenAI is rolling back a recent update to GPT-4o, the default model that powers ChatGPT, following complaints from users that it made the chat bot act like a weirdo. "The last couple of GPT-4o updates have made the personality too sycophant-y and annoying (even though there are some very good parts of it), and we are working on fixes asap, some today and some this week," said OpenAI CEO Sam Altman in a X post spotted by TechCrunch. As of midday Tuesday, Altman said ChatGPT was running on an older, less sycophantic version of GPT-4o for all free users. The company hopes to get paid users back on an older release of the model by later today. "We're working on additional fixes to model personality and will share more in the coming days," Altman said, adding OpenAI would share more information about what went wrong "at some point."

Meta has unveiled a new AI app that combines chatbot features with a social media experience. Launched on Tuesday for the iPhone, iPad, and Android devices, the Meta AI app offers most of the usual aspects of an AI app. You can get information, generate content, and analyze photos and other images. "Meta AI is built to get to know you, so its answers are more helpful," Meta said in a news release. "It's easy to talk to, so it's more seamless and natural to interact with. It's more social, so it can show you things from the people and places you care about. And you can use Meta AI's voice features while multitasking and doing other things on your device, with a visible icon to let you know when the microphone is in use."

As Meta's first-ever generative AI conference gets underway, the company is also previewing a significant update on its plans to bring AI features to WhatsApp chats. Buried in its LlamaCon updates, the company shared that it's working on something called "Private Processing," which will allow users to take advantage of generative AI capabilities within WhatsApp without eroding its privacy features. According to Meta, Private Processing is an "optional capability" that will enable people to "leverage AI capabilities for things like summarizing unread messages or refining them, while keeping messages private." WhatsApp, of course, is known for its strong privacy protections and end-to-end encryption. That would seem incompatible with cloud-based AI features like Meta AI.
