• OpenAI rolled out a new image generation feature for ChatGPT and it was a hit with users.
• Sam Altman, OpenAI's CEO, said the company had to introduce rate limits because "our GPUs are melting."
• Altman said the experience reminded him of his early days as a Y Combinator-backed founder.

OpenAI's CEO Sam Altman said on Tuesday that handling the ChatGPT maker's new product releases are reminding him of his early days as a Y Combinator-backed founder.

"Lol I feel like a YC founder in 'build in public' mode again," Altman wrote in a post on X.

Altman's remark comes after a busy week for OpenAI. The company released a new image generation feature for ChatGPT on March 25.

The new feature was a hit with users, who flooded social media with AI-generated images in the style of Japanese animation firm Studio Ghibli's films. Altman said in an X post on Monday that OpenAI saw a record spike in users after the feature was rolled out.

But the sudden uptick in users did cause some problems for OpenAI.

On Thursday, just two days after the new feature was released, Altman said that OpenAI's "GPUs are melting" from all the image generation requests they were getting from users.

"It's super fun seeing people love images in ChatGPT. But our GPUs are melting. We are going to temporarily introduce some rate limits while we work on making it more efficient," Altman wrote on X.

Then, in a subsequent X post made on Tuesday, Altman said the company was "getting things under control." He added that users "should expect new releases from OpenAI to be delayed, stuff to break, and for service to sometimes be slow as we deal with capacity challenges."

Altman may be best known for his work at OpenAI now, but the entrepreneur cut his teeth in the tech world at Y Combinator. The startup accelerator counts organizations like Airbnb, Dropbox, Stripe, and Twitch as alumni companies.

Altman's first startup, a social networking application named Loopt was one of the first few companies to be backed by Y Combinator in 2005. Loopt was later acquired by Green Dot, a banking company, in 2012 for over $43 million.

In 2014, Y Combinator's founder Paul Graham named Altman as his successor. Altman replaced Graham as Y Combinator's president, and held the role for five years. Altman stepped down as president in March 2019 to focus on OpenAI.

On Monday, OpenAI announced it had raised $40 billion at a $300 billion valuation. OpenAI's new valuation is nearly double what it was worth in October, when it raised $6.6 billion at a $157 billion valuation.

Representatives for Altman at OpenAI did not respond to a request for comment from Business Insider.

Kelly Stafford put on a happy face while celebrating her and Matthew Stafford’s twin daughters’ birthdays with a Paris-themed party — despite wanting to cancel it days prior.

“We have eight-year-olds ,” Kelly, 35, wrote via Instagram on Monday, March 31, toasting daughters Sawyer and Chandler’s special day. “Love watching each of them grow individually while holding tight to their bond. It’s truly so special.”

Kelly’s post revealed that she and Matthew, 37, moved forward with the girls’ party over the weekend even though they briefly canceled it as punishment for their recent actions.

The bash was a paint party where the girls and their guests painted Eiffel Tower pictures and wore berets. The French-theme was also evident by the birthday girls’ matching Eiffel Tower T-shirts and cake toppers.

Where Kelly Stafford Draws the Line on Her Daughters’ Birthday Invites

Kelly and Matthew’s two youngest daughters, Hunter, 6, and Tyler, 4, were also in attendance for the celebration and wore berets in a sweet family photo.

The Los Angeles Rams quarterback even got in on the fun, posing for a photo with one of the twins while she had on an apron and held up her paintbrush.

Kelly previously revealed that Sawyer and Chandler’s event was in jeopardy days before their special day because they were misbehaving at home.

“I have two children — I’m not going to name their names — but they have decided that they run the world and that they know what’s best and they have all the attitude now,” Kelly said during the Thursday, March 27, episode of her “The Morning After” podcast. “I’m tired.”

Although Kelly didn’t explicitly identify her eldest daughters as the culprits, she hinted at it. “This has been an ongoing thing for the last couple of months where the attitudes have come into play,” Kelly explained. “I’m struggling to parent it. I am an enforcer. I am probably the mean parent.”

She recalled, “Matthew has now turned also. We tried the ‘good cop, bad cop’ situation that we always are. Clearly, it’s not working because nothing has changed.”

As a result, Kelly revealed, “We told them, ‘Birthday party is off because we cannot honestly celebrate you guys right now just because of the way you’re behaving. We love you, but I don’t think you should have a celebration.’”

She confessed it was “a really hard decision to make” because it “hurts you as much as it hurts them.”

Despite being ready to cancel, Kelly said she and Matthew learned that they couldn’t “get our deposit back” for the venue, so they were forced to retract their statement.

“I had to tell them the party was back on,” she said. “I was like, ‘It is not because you changed your behavior. It is solely because Mommy and Daddy couldn’t get our money back.’”

Earlier this year, Kelly revealed that there have been a lot of parenting changes she’s had to face as her daughters have gotten a little older — including what to share on social media.

“I always told myself the minute they know what Instagram is, is the minute I have to figure something out. And my older ones know what it is,” Kelly exclusively told Us Weekly in February.

She noted that her twins’ friends have even started to follow her on Instagram, which isn’t something she anticipated.

“Our generation grew up in the weird time where we started to have [social media],” Kelly recalled. “But the generation before us, social media was new and their kids have it. But they don’t really know the pros and cons of it. But our generation knows what can happen and the dangers of it.”

The podcast host, who married Matthew in April 2015, confessed that while social media is a “tool” for her career, she can’t help but “fear for my kids” being online.

“That is a whole different ball game,” Kelly explained. “I pray that something happens to social media before they get to that point, even though I know it probably won’t.”

We’ve been told to take our vitamins ever since we were kids, but as we get older, it becomes even more important. But which vitamins should we be taking, exactly? That’s the hard part. Just sifting through the vitamin section at your local drugstore can be beyond overwhelming — there are so many options!

Knowing what you actually need depends on your doctor’s recommendations, but most people should benefit from a multivitamin and omegas, which support overall health.

Unilever may be investing billions of dollars into influencer marketing, but marketers aren’t necessarily copying their playbook just yet.

When one of the world’s largest advertisers says it will now invest half of its ad budget (some $8.5 billion globally in 2023, per Statista) on social media with plans to work with 20 times more influencers, it can make waves — enough that small and medium-sized marketers rush to follow suit.

But before marketers consider doing so, they need to remember that the creator economy isn’t just another media channel but an ecosystem all its own with potential hazards along the way.

Amazon Ads’s quest to become the first programmatic port of call for media buyers is intensifying. 

It’s courting media agencies across the industry hoping that more will treat its demand-side platform (DSP) as their go-to programmatic provider. According to 11 media buyers who spoke to Digiday, its pitch to decision-makers emphasizes a refreshed user interface, CTV inventory, and, in select cases, financial incentives. Along the way, it hopes to expand its advertiser base to include more non-endemics.

While it’s far from winning over the industry, it’s gained media buyers’ attention — and likely that of market incumbents The Trade Desk and Google’s DV360.

Uncertainty around TikTok’s future in the U.S. led many advertisers to slam the brakes on their advertising there. Others treated the turmoil as a green light. 

Walmart, Coca-Cola, Comcast, PepsiCo, Warner Bros Discovery, Google and Amazon have increased their U.S. social media spend on the platform by two percentage points, on a year-over-year basis in the first quarter of 2025, according to Sensor Tower. 

Those seven brands were also some of TikTok’s top spending U.S. advertisers in 2024, per the market intelligence firm. However, PepsiCo and Amazon declined to comment on this, while the other five companies did not respond to Digiday’s request for comment.

Get with the programmatic

Programmatic has firmly become part of the upfront. “There was a huge swing last year,” said one agency executive, referring to TV network and streaming services being more willing to allow advertisers’ programmatic spend to count toward their upfront commitments.

With influencer marketing budgets steadily rising, more multinational brands are partnering with influencer agencies as the industry becomes more complex.

The World Federation of Advertisers released a report today showing that some 54% of multinational brand marketers plan to boost influencer marketing spend in 2025, with 61% agreeing that influencer marketing will become more important in the future. However, due to ongoing challenges navigating the space, like issues with disclosures and transparency on creator campaigns, more brands are employing the help of agencies that play a role in influencer marketing.

“Budgets will reflect this as will the increased usage of partners with expertise in influencer marketing,” said Will Gilroy, director of communications and strategy at WFA. “But this opportunity is a double-edged sword unless we get it right through responsible practices.”

Being small and less data-dependent aren’t always selling points for attracting search advertisers. But in the case of one privacy-focused browser, both are core selling points.

Since introducing search ads in 2024, Brave has courted big brand budgets, pitching itself as the place to squeeze out incremental gains beyond Google’s well-trodden turf.

Part of its differentiation lies in how it matches ads to queries without using behavioral or personal data. Rather than relying on traditional keyword targeting — and the endless back-and-forth of asking marketers “what keywords do you want?” Using embeddings, Brave offers contextual ads with a system mapping queries and ads into the same semantic space, allowing it to match users with relevant results based on meaning and intent, not just exact phrasing.
