Catch up on the day’s stories: Beach reading, new AI technology, parental burnout

CNN’s 5 Things PM brings you the stories you might have missed during your busy day.

👋 Welcome to 5 Things PM! OpenAI unveiled a new artificial intelligence large language model designed to be easier and more intuitive to use. The latest version, dubbed GPT-4o, basically turns ChatGPT into a digital personal assistant that can engage in real-time, spoken conversations. OpenAI is trying to stay ahead of rivals Google and Meta in the highly competitive AI arena. Here’s what else you might have missed during your busy day: 1️⃣ Beach reading: Summer is right around the corner, and if your vacation plans include lounging by the water you’ll probably bring a page-turning thriller or a trashy romance novel to help pass the time. These types of books have become an unofficial genre all their own, and they’re almost always marketed to women. 2️⃣ Airline fees: Major airlines are suing the federal government over new rules that would require carriers to disclose all fees up front, including those for checked and carry-on bags as well as change and cancellation fees. 3️⃣ ‘Upcycled’ clothing: It’s surging in popularity thanks to the demand for streetwear and vintage products. But some luxury brands are pushing back because they’re concerned about their bottom line, brand image and counterfeit items. 4️⃣ Parental burnout: A recent survey found that more than half of parents were feeling overwhelmed by the pressure cooker of everyday life. Experts suggest adjusting your expectations and embracing the concept of “good enough.”
