OpenAI released a new base model on Thursday called GPT-4.5, which the company said is its best and smartest model for chat yet. Its not a reasoning model like OpenAIs o1 and o3 models, but it can be used to train other models to be reasoning models. Notably, GPT-4.5 was trained using 10 times the computing power (scores of GPUs in data centers) than its predecessor, GPT-4o. The result is a model whose outputs feel more natural and human, OpenAI said in its press release, and demonstrate a better general understanding of the world. Its writing and programming skills are better, and it hallucinates less. It also displays a higher level of emotional intelligence about the user and what theyre trying to do. For example, when prompted with Im going through a tough time after failing a test, the model responded: Aw, I’m really sorry to hear that. Failing a test can feel pretty tough and discouraging, but remember, it’s just one momentnot a reflection of who you are or your capabilities. OpenAI cofounder and former researcher Andrej Karpathy, who got early access to the model, posted on X that the improvements are subtle but meaningful. Everything is a little bit better and it’s awesome, but also not exactly in ways that are trivial to point to, Karpathy continued; also, the model appears to have improved by 20% in everything it does rather than improving by several times over in certain domains or skills. OpenAI said GPT-4.5s performance proves that supersizing models, training data, and computing power can still produce significant performance gains. However, a debate has been raging over this assertion on X. Karpathy saw evidence of this in his tests: [I]t is incredibly interesting and exciting as another qualitative measurement of a certain slope of capability that comes for free from just pretraining a bigger model. Of course, free is stretching it: Training costs for a model as big as GPT-4.5 could approach $1 billion. OpenAI is releasing GPT-4.5 as a research preview to ChatGPT Pro users and to developers who pay to access OpenAI models through an API. It will become available to ChatGPT Plus and Team users next week, the company says.

Its well-documented that older women have been less represented in mainstream media and female actors over 40 are less likely to get work compared to their male counterparts. The stigma surrounding aging women in entertainment has been so pervasive that many actresses have felt forced to hide the natural realities of aging. Actress Naomi Watts recently revealed, I was told I would never work again if I admitted to being menopausal. Her experience is not uniquemany women in the industry have echoed similar sentiments, facing a shrinking pool of opportunities as they age. This years award show season has shown that the tides are turning. Weve started to see a shift with actresses in Hollywood experiencing success later in life. One of the most discussed films of the past year, The Substance, tackles ageism head-on. And in a historic moment, Demi Moore44 years into her careerwon her first Golden Globe at 62 and received an Academy Award nomination for Best Actress. During the Golden Globes, we saw seven of the Best Actress nominations go to women over the age of 40. These nominations signal a growing recognition that talent doesnt have to have an expiration date. For decades Hollywood has created the perception that women in their 40s and beyond, often when they are perimenopausal or menopausal, are past their primes and reaching the end of their careers. Moore previously shared that she almost quit acting because of ageism and how difficult it can be, particularly for women over 50. However, this cultural shift in Hollywood’s acceptance and celebration of aging women could change how this demographic is represented. Now the question is, will we see other industries shift their perceptions of midlife women? Heres why they should. Outdated research has failed menopausal women Before looking ahead, we have to understand how we got here. The societal stigma around aging has often overlapped with menopause, and unfortunately, thats led to a negative perception of this transitional period of a womans life. Menopause has been widely understudied. For example, a study in Nature Aging has shown that researchers havent properly considered menopause in 99% of studies of the biology of aging. Furthering the stigma, outdated research has led to a lack of treatment options for women experiencing menopause symptoms. The use of hormone therapy to treat menopause symptoms stopped nearly overnight due to a study showing that hormone therapy increased the risks of cancer. However, recent studies have debunked that theory and shown the benefits of hormone therapy outweigh the risks. The lack of research and controversial history around hormone therapy has hurt menopause care and prevented aging women from getting the adequate support they need. That all is changing. What the entertainment industry can teach Companies can take a page from Hollywoods playbook by supporting and empowering its female senior talent. Women in their 40s, 50s, and 60s are some of the most experienced managers, leaders, and mentors in the workplace. As they age, they are also often at the height of their careers. McKinsey and Lean In found that female leaders contribute more to employee engagementincluding creating an inclusive workplace and mentorshipthan their male counterparts, and another McKinsey report found that organizations with gender diversity of executive teams were 25% more likely to have above-average profitability compared to those who didnt. Senior female leaders are an essential part of the workforce. Yet according to our 2022 Menopause in the Workplace report, 46% of working women experiencing menopause said their 50s have been the most difficult time in their careers. Our latest data also showed that 50% of Gen X women have experienced ageism at work. Now is a critical time for companies to step up and support. Organizations must invest in meeting the evolving needs of their midlife female workforce. Investing in menopause support for senior women leaderssuch as access to specialized providers, educational resources, and coverage for hormone therapyenables these women to manage their symptoms effectively, remain at peak productivity, and pave the way for the next generation of female leaders. What happens in Hollywood strongly influences culture, including workplaces. On March 2, Moore is up for her first Oscar for her critically acclaimed role. No matter who wins, its a victory for Moore and all aging women at work. Asima Ahmad, MD, MPH, FACOG is cofounder and Chief Medical Officer of Carrot Fertility.

From the rising cost of eggs and the staggering cost of housing, the constant chaos from mass government firings to the tariff threats against Canada and Mexico, Americans are struggling to cope with rampant economic uncertainty the best way they can: doom spending. One in 5 Americans say they are buying more than usual, “purchasing items excessively or impulsively in response to fears or anxiety about future events,” according to a recent report by CreditCards.com. The act of buying things as a way to self-soothe and cope with discomfort can be particularly problematic, especially when you’re worried about your personal finances and the economy at large in the first place. The survey, published in February 2025, examines consumer spending habits since President Donald Trump took office and focuses on the role economic factors and uncertainty play. Here are some key findings. Americans are buying more, driven by Trump tariffs President Trump’s proposed tariffs are weighing heavily on many people’s minds. In fact, more than one in 4, or 29%, of respondents say fear of Trumps tariffs greatly impacts their desire to make additional purchases. Trump has said, starting March 4 (next week!), he will slap a 25% tariff on goods from Canada and Mexico and may in the future even broaden the scope to include automobiles, pharmaceuticals, and semiconductorsall of which means higher prices for American consumers already dealing with cost of living concerns and inflation. Digging a little further, the report shows 19% of respondents say they are buying significantly (5%) or slightly more (14%) items than usual, and of this group, 29% say fear of Trumps tariffs greatly impacts their desire to make additional purchases, while 37% say its having some impact. Another pandemic also prompts spending The report found that 3 in 10 respondents are purchasing items to prepare for another pandemic. Meanwhile, 42% say they are, or will start, stockpiling items, mainly food and toilet paper. Also, since November 2024, 28% of respondents say they have made one large purchase (over $500) and 21% say they soon plan to. The most common of those large purchases were electronics (39%), home appliances (31%), and home improvement materials (25%). People also bought furniture (22%) and cars (17%). Finally, and perhaps the most worrisome finding of the report, is that 34% of respondents say they are likely to worsen or go into credit card debt this year to secure purchases.
