OpenAI announced its new, more powerful GPT-4 Turbo artificial intelligence model Monday during its first in-person event, and revealed a new option that will let users create custom versions of its viral ChatGPT chatbot. It’s also cutting prices on the fees that companies and developers pay to run its software.
OpenAI’s announcements show that one of the hottest companies in tech is rapidly evolving its offerings in an effort to stay ahead of rivals like Anthropic, Google and Meta in the AI arms race. ChatGPT, which broke records as the fastest-growing consumer app in history months after its launch, now has about 100 million weekly active users, OpenAI said Monday. More than 92% of Fortune 500 companies use the platform, up from 80% in August, and they span across industries like financial services, legal applications and education, OpenAI CTO Mira Murati told reporters Monday.
The event also included a surprise appearance by Microsoft CEO Satya Nadella.
“The systems that are needed as you aggressively push forward on your road map require us to be on the top of our game, and we intend fully to commit ourselves fully to making sure you all… have not only the best systems for training and inference, but also the most compute,” Nadella told OpenAI CEO Sam Altman while onstage together. He added, “That’s the way we’re going to make progress.”
Earlier this year, Microsoft‘s expanded investment in OpenAI — an additional $10 billion — made it the biggest AI investment of the year, according to PitchBook, and in April, the startup reportedly closed a $300 million share sale at a valuation between $27 billion and $29 billion, with investments from firms such as Sequoia Capital and Andreessen Horowitz. As recently as last month, OpenAI was reportedly in talks to close a deal that would lead to an $80 billion valuation.
In his speech Monday, Altman said the day’s announcements came from conversations with developers about their needs over the past year. And when it comes to GPT-5, Altman told reporters, “We want to do it, but we don’t have a timeline.”
Here’s what OpenAI announced Monday:
GPT-4 Turbo
OpenAI ChatGPT
GPT-4 Turbo is the latest AI model, and it now provides answers with context up to April 2023. Prior versions were cut off at January 2022. For example, if you asked GPT-4 who won the Super Bowl in February 2022, it wouldn’t have been able to tell you. GPT-4 Turbo can.
“We are just as annoyed as all of you, probably more, that GPT’s knowledge about the world ended in 2021,” Altman said in a speech Monday.
It also accepts a lot more input. While earlier versions limited you to about 3,000 words, the GPT-4 Turbo accepts inputs of up to 300 pages in length. It means you could ask it to summarize entire books.
GPT-4 also supports DALL-E 3 AI-generated images and text-to-speech. It also has six preset voices to choose from, so you can choose to hear the answer to a query in a variety of different voices.
OpenAI said GPT-4 Turbo is available in preview for developers now and will be released to all in the coming weeks.
OpenAI said it’s also cutting the prices for developers. “GPT-4 Turbo input tokens are 3x cheaper than GPT-4 at $0.01 and output tokens are 2x cheaper at $0.03,” the company said, which means companies and developers should save more when running lots of information through the AI models.
Personalized chatbots

Until now, ChatGPT’s enterprise and business offerings were the only way people could upload their own data to train and customize the chatbot for particular industries and use cases. Now it’s adding the option for anyone to create custom chatbots.
AI “agents” are one of the buzziest uses of the technology recently, with many startups vying to offer the kind of personalized AI tools that consumers may already be familiar with via pop culture representations, such as Tony Stark’s J.A.R.V.I.S. in Marvel movies, or Pam in Disney Channel’s Smart House.
“Anyone can easily build their own GPT—no coding is required,” the company wrote in a release. “You can make them for yourself, just for your company’s internal use, or for everyone.Creating one is as easy as starting a conversation, giving it instructions and extra knowledge, and picking what it can do, like searching the web, making images or analyzing data.”
More than two million developers building their own tools using ChatGPT’s API will also be able to customize the chatbot, meaning consumers will likely see personalized AI chatbots popping up in many more places, including apps and websites they use regularly.
Open AI’s version of the App Store

Now that users and developers can launch their own, personalized AI chatbots, OpenAI is introducing a new revenue driver for the company: Its own version of the app store.
The GPT Store allows people who create their own GPTs to make them available for public download, and in the coming months, OpenAI said people will be able to earn money based on their creation’s usage numbers.
“Once in the store, GPTs become searchable and may climb the leaderboards,” the company wrote in a release. “We will also spotlight the most useful and delightful GPTs we come across in categories like productivity, education, and ‘just for fun.'”
As for revenue share for people who create custom chatbots featured in the store, the company will start with “just sharing a part of the subscription revenue overall,” Altman told reporters Monday. Right now, the company is planning to base the payout on active users plus category bonuses, and may support subscriptions for specific GPTs later.
“What OpenAI is really in the business of selling is intelligence — and that, and intelligent agents, is really where it will trend over time,” Altman told reporters.
New all-in-one image-generation, browsing and summarization
Until Monday, ChatGPT users had to hop between different apps and websites to use all of OpenAI’s tools, which contributed to a slightly higher learning curve. On Monday, the company announced it has streamlined its AI tools into one place: Using ChatGPT now offers image generation via DALL-E, browsing, data analysis, document upload and PDF search. Before now, Anthropic’s Claude was the only competitor chatbot to allow PDF search.
Copyright shield
As generative AI-related legal action is on the rise, Altman announced Monday that OpenAI will “step in and defend our customers” and “pay the costs incurred if you face legal claims around copyright infringement.” It echoes similar statements made by Google, Microsoft and Adobe.
White House trade advisor Peter Navarro chastised Apple CEO Tim Cook on Monday over the company’s response to pressure from the Trump administration to make more of its products outside of China.
“Going back to the first Trump term, Tim Cook has continually asked for more time in order to move his factories out of China,” Navarro said in an interview on CNBC’s “Squawk on the Street.” “I mean it’s the longest-running soap opera in Silicon Valley.”
CNBC has reached out to Apple for comment on Navarro’s criticism.
President Donald Trump has in recent months ramped up demands for Apple to move production of its iconic iPhone to the U.S. from overseas. Apple’s flagship phone is produced primarily in China, but the company has increasingly boosted production in India, partly to avoid the higher cost of Trump’s tariffs.
Trump in May warned Apple would have to pay a tariff of 25% or more for iPhones made outside the U.S. In separate remarks, Trump said he told Cook, “I don’t want you building in India.”

Analysts and supply chain experts have argued it would be impossible for Apple to completely move iPhone production to the U.S. By some estimates, a U.S.-made iPhone could cost as much as $3,500.
Navarro said Cook isn’t shifting production out of China quickly enough.
“With all these new advanced manufacturing techniques and the way things are moving with AI and things like that, it’s inconceivable to me that Tim Cook could not produce his iPhones elsewhere around the world and in this country,” Navarro said.
Apple currently makes very few products in the U.S. During Trump’s first term, Apple extended its commitment to assemble the $3,000 Mac Pro in Texas.
In February, Apple said it would spend $500 billion within the U.S., including on assembling some AI servers.

Artificial intelligence hyperscaler CoreWeave said Monday it will acquire Core Scientific, a leading data center infrastructure provider, in an all-stock deal valued at approximately $9 billion.
Coreweave stock fell about 4% on Monday while Core Scientific stock plummeted about 20%. Shares of both companies rallied at the end of June after the Wall Street Journal reported that talks were underway for an acquisition.
The deal strengthens CoreWeave’s position in the AI arms race by bringing critical infrastructure in-house.
CoreWeave CEO Michael Intrator said the move will eliminate $10 billion in future lease obligations and significantly enhance operating efficiency.
The transaction is expected to close in the fourth quarter of 2025, pending regulatory and shareholder approval.

The deal expands CoreWeave’s access to power and real estate, giving it ownership of 1.3 gigawatts of gross capacity across Core Scientific’s U.S. data center footprint, with another gigawatt available for future growth.
Core Scientific has increasingly focused on high-performance compute workloads since emerging from bankruptcy and relisting on the Nasdaq in 2024.
Core Scientific shareholders will receive 0.1235 CoreWeave shares for each share they hold — implying a $20.40 per-share valuation and a 66% premium to Core Scientific’s closing stock price before deal talks were reported.
After closing, Core Scientific shareholders will own less than 10% of the combined company.

Apple on Monday appealed what it called an “unprecedented” 500 million euro ($586 million) fine issued by the European Union for violating the bloc’s Digital Markets Act.
“As our appeal will show, the EC [European Commission] is mandating how we run our store and forcing business terms which are confusing for developers and bad for users,” the company said in a statement. “We implemented this to avoid punitive daily fines and will share the facts with the Court.”
Apple recently made changes to its App Store‘s European policies that the company said would be in compliance with the DMA and would avoid the fines.
The Commission, which is the executive body of the EU, announced its fine in April, saying that Apple “breached its anti-steering obligation” under the DMA with restrictions on the App Store.

“Due to a number of restrictions imposed by Apple, app developers cannot fully benefit from the advantages of alternative distribution channels outside the App Store,” the commission wrote. “Similarly, consumers cannot fully benefit from alternative and cheaper offers as Apple prevents app developers from directly informing consumers of such offers.”
Under the DMA, tech giants like Apple and Google are required to allow businesses to inform end-users of offers outside their platform — including those at different prices or with different conditions.
Companies like Epic Games and Spotify have complained about restrictions within the App Store that make it harder for them to communicate alternative payment methods to iOS users.
Apple typically takes a 15%-30% cut on in-app purchases.
