Theres a cat-and-mouse game between those using generative AI chatbots to produce text undetected and those trying to catch them. Many believe they know the telltale signsthough as a journalist fond of the word delve and prone to em-dashes, Im not so sure. Researchers at four U.S. universities, however, have taken a more rigorous approach, identifying linguistic fingerprints that reveal which large language model (LLM) produced a given text. All these chatbots are coming out every day, and we interact with them, but we dont really understand the differences between them, says Mingjie Sun, a researcher at Carnegie Mellon University and lead author of the study, which was published in Cornell Universitys preprint server arXiv. By training a machine learning classifier to do this task, and by looking at the performance of that classifier, we can then assess the difference between different LLMs. Sun and his colleagues developed a machine learning model that analyzed the outputs of five popular LLMs, and was able to distinguish between them with 97.1% accuracy. Their machine learning model uncovered distinct verbal quirks unique to each LLM. ChatGPTs GPT-4o model, for instance, tends to use utilize more than other models. DeepSeek is partial to saying certainly. Googles Gemini often prefaces its conclusions with the word essentially, while Anthropics Claude overuses phrases like according to and according to the text when citing its sources. xAIs Grok stands out as more discursive and didactic, often reminding users to remember key points while guiding them through arguments with not only and but also. The writing, the word choices, the formatting are all different, says Yida Yin, a researcher at the University of California, Berkeley, and a coauthor of the paper. These insights can help users select the best model for specific writing tasksor aid those trying to catch AI-generated text masquerading as human work. So, remember: according to this study, if a model utilizes certain words, its certainly possible to identify it.

America has been dealing with a bird flu outbreak for some time, and now fears over possible contamination in cat food have led to a recall. Heres what to know about the recall of cat food linked to possible bird flu contamination. Whats happened? On March 1, the U.S. Food and Drug Administration (FDA) published a recall notice relating to certain products sold by Wild Coast LLC (dba Wild Coast Raw) of Olympia, Washington. The recalled products are raw pet food for cats. The reason? The products may be contaminated with Highly Pathogenic Avian Influenza (HPAI) H5N1, better known as bird flu. The bird flu virus can live in manufactured products, including pet food that has been made with contaminated birds. The notice posted on the FDAs website expands on a mid-February public health alert from the Washington State Department of Agriculture warning that it found the presence of HPAI in multiple cats and the same cat food they consumed. That cat food was Wild Coast LLC Boneless Free Range Chicken Formula with lot numbers #22660 and #22664 and the Best By Date 12/2025, according to the notice. However, the notice posted on the FDAs website on March 1 widens the list of products that could be affected. That notice is about a voluntary recall initiated by Wild Coast LLC.

Over the past decade, as I’ve curated this annual list of best bags, there’s been a strong focus on utility. But this year, bag designers are eager to create bags that make a statement, while also improving women’s lives with useful features. In some ways, the bag industry is coming full circle. When I first started working on this list, the bag industry was dominated by big brands like Coach and Kate Spade that were more concerned with fashion than function. But then, a new generation of direct-to-consumer brands like Dagne Dover, Cuyana, and Senreve popped up, creating bags full of features like laptop and water bottle sleeves that helped women get through busy days. In some ways, these startups changed the entire universe of bag designs. Now, functionality is table stakes for bag designers, says Karla Gallardo, co-founder and CEO of Cuyana. The trick is creating a highly functional bag that’s also spectacular. Many new bags on the market today are meant to stand out and allow the wearer to express herself. They come in architectural shapes, with interesting silhouettes. But they are all designed to get you from packed days at work to the weekend to your long flight. Here is our pick of the best work-life bags of 2025. And they all happened to be created by women-owned startups. Cuyana Mila Satchel, $798 If you’re looking for a bag that will make an impression, consider the Mila. It’s the kind of structurally gorgeous bag that will elevate your look as you go in to an important board or investor meeting. Cuyana spends many years designing bags, then testing them with customers to continue making tweaks and improvements. This particular bag is specifically designed for travelers. It has a travel sleeve that fits over luggage and importantly, it has a wide base so it can sit under the seat in front of you. And you can carry it two ways, with the wide short handles or with a strap that you can clip on. When it opens, everything is easily accessible and visible. There’s a slot for your laptop, as well as pockets for your phone and a clip for your key. You can even purchase a clutch that clips into Mila, so you can leave the big bag at home and take the smaller bag out to dinner. The whole system is designed to save you time on high-pressure days. Parker Thatch Jane, starting at $698 These days, with hybrid work, the amount we need to carry every day varies tremendously. Some days, you need to carry your laptop and files, the next day, you might just need a wallet and chapstick. Parker Thatch, a California-based label, believes your bag should magically shrink and expand depending on what you’re doing for the day. That’s precisely what it has achieved with its Jane bag. It’s made from soft, buttery leather that can fit a large laptop. But when the bag isn’t full, it collapses in an elegant way that gives you a relaxed, put together look. It comes in a wide range of colors to suit different aesthetics. The navy and espresso will fit into a more formal workplace, but you can also opt for leopard print, platinum, or camo with a red stripe if you want to go bolder. Clare V. Bateau Tote, $475 For another collapsible bag, Clare V.’s Bateau tote also has an amazing ability to transform. On the surface, it has a simple tote silhouette that can fit a laptop along with everything you might need for your workday. It has an over the shoulder strap for easy carrying. But when you don’t need to fill it up, can collapse the tote into a much smaller bag by bringing the two edges together. You can then carry it with short handles which happen to have the word Ciao on them, in a quirky bohemian style Clare V. is known for. This tote is very practical, but it is also fun and unique. As icing on the cake, this bag has a gorgeous texture that weaves two colors of blue together to create a checker pattern. Oleada Wavia Bag Plus, starting at $635 If you need to head to the office every day and are constantly on the road for business trips, you need a bag that will allow you to easily carry a lot of heavy items, including your laptop and documents. There are many travel brands that sell products that do the job, but they don’t look stylish. Oleada’s Wavia bag wants to be both. It has clean lines and a curved wave design, and it is packed with useful features. It can be carried as a backpack, a shoulder bag, a cross-body and a handbag. It has a luggage sleeve that allows you to put it on your rolling luggage. And even has a lock closure to keep the bag securely closed. Since the bag is designed around your laptop, it comes in two sizes: 13 inch and 16 inch. You can get it in either leather or a vegan synthetic material that comes in a wide range of colors. And importantly, no matter what material you choose, the bag is very light, weighing in at around 2 lbs. Linquist Hilma, $750 Linquist, a studio studio based in Rhode Island, creates bags that are inspired by works of art. The Hilma, for instance, is designed around by the pleasing shape of an ellipse, with an oval base and a gradually widening top. The bag is named after Hilma af Klint, a Swedish artist who was among the first abstract artists in Western art history. Her paintings are grounded in geometric shapes, exploring how these figures appear both in the body and in the natural world. The Hilma bag is big enough to get you through busy days, and it is designed to be worn for a long time. It is handmade in Rhode Island by a team of artisans, and crafted from full grain Vachetta leather that is not treated with preservatives or chemicals. Over time, the material is designed to patina as it is exposed to your hands and the elements. It comes in a wide array of colors, but because it is made in small batches, different colors are available at different times.
