ChatGPT 5 vs 4: Here are key features and pricing differences between OpenAI models
The rollout is significant to OpenAI's accessibility strategy, with free users now gaining access to a reasoning-capable model for the first time.
Advanced reasoning and safer outputs
One of the most notable differences between GPT-5 and GPT-4 is the model's enhanced reasoning capability. OpenAI said GPT-5 has been trained to 'think' before responding, engaging in internal chains of thought to generate more accurate and context-aware answers.
GPT-5, according to CNBC, fabricates less information compared to GPT-4. The model has been trained to recognize when a task is incomplete, avoid speculation, and clearly explain its limitations. This reduces hallucinations and improves transparency. In cases of potentially risky queries, GPT-5 uses a new technique called 'safe completions' which offers high-level answers within secure boundaries without entirely refusing to respond.
Michelle Pokrass, a post-training lead at OpenAI, told the outlet that the focus was on reducing unsupported claims while making the model more helpful and clear.
Performance across domains
GPT-5 is also significantly faster than GPT-4, OpenAI said. The model does not excel in writing, coding, education and healthcare-related use cases.
During a demonstration, GPT-5 was asked to build a French-learning web app with flashcards and quizzes based solely on a written prompt. Within seconds, the model generated fully functional applications with different themes, which showcased its improved design and development abilities.

New tools and broader access
Unlike previous versions, GPT-5 integrates every major OpenAI tool. Users can now access web search, image generation, voice capabilities, and advanced creative tools like Canvas within the same interface. GPT-5 is also being deployed across Microsoft products like Microsoft 365 Copilot and Azure AI Foundry.
Additionally, three model variants are available via OpenAI's API: GPT-5, GPT-5-mini, and GPT-5-nano, designed for different performance and cost requirements.
Expanded access across pricing tiers
The GPT-5 is currently accessible to all tiers of usage. Free-tier people have access to GPT-5 until they hit the limits of usage; afterward, they shall be entitled to GPT-5 mini. Plus-tier users enjoy higher caps on usage, while unlimited access to GPT-5 Pro is given to Pro-tier users. Also, API access is available for developers, the CNBC report added.
According to the developer launch blog, GPT-5 will cost developers using the API $1.25/1M to input tokens and $10/1M to output tokens. 'GPT-5 mini is priced at $0.25/1M input tokens and $2/1M output tokens, and GPT-5 nano is priced at $0.05/1M input tokens and $0.40/1M output tokens,' it adds. For comparison, developers often use Gemini 2.5 Flash and Flash-Lite since it's so cheap: GPT-5 nano is now cheaper.

OpenAI staff plan to sell $6 billion in stock to SoftBank, other investors
Current and former OpenAI employees plan to sell approximately $6 billion worth of shares to an investor group that includes Thrive Capital, SoftBank Group Corp. and Dragoneer Investment Group, in a deal that values the ChatGPT maker at $500 billion, according to people familiar with the matter. The talks are early and the size of the share sale could still change, said the people, who asked not to be identified discussing private information. The secondary share investment is on top of SoftBank's commitment to lead OpenAI's $40 billion funding round, which values the company at $300 billion, according to another person familiar with the deal. That round remains ongoing, with OpenAI recently securing $8.3 billion from a syndicate of investors. Representatives for Dragoneer and Thrive didn't respond to requests for comment. Spokespeople for OpenAI and SoftBank declined to comment. All three firms are existing OpenAI backers. Allowing employees to sell shares is an important tool for startups trying to retain top talent, without requiring the company to go public or be acquired. In some cases, early investors also use these deals to sell down their stakes, though OpenAI investors are not eligible to do so in this round, according to a person familiar with the matter. Current and former employees who spent at least two years at the company are able to participate. With its participation in the share sale, as well as its previous commitments, SoftBank is making a pivotal bet on the success of OpenAI. In addition to those deals, the Japanese conglomerate headed by Masayoshi Son recently closed a separate $1 billion purchase of OpenAI employee shares at a $300 billion valuation, according to a person familiar with the matter. Negotiations for that deal started before talks around the $500 billion secondary valuation began, they said. The $500 billion valuation would make OpenAI the world's most valuable startup, surpassing Elon Musk's SpaceX. The company expects revenue to triple this year to $12.7 billion, up from $3.7 billion in 2024, Bloomberg has reported. And the secondary deal talks come on the heels of the release of its highly-anticipated GPT-5 model. This week, OpenAI chief Sam Altman sat down with a group of reporters and shared his vision for the company, including that it wants to spend trillions of dollars on the infrastructure required to run AI services in the 'not very distant future.' 'You should expect a bunch of economists to wring their hands and say, 'This is so crazy, it's so reckless,' and whatever,' Altman said. 'And we'll just be like, 'You know what? Let us do our thing.''

OpenAI could buy Google Chrome, says Sam Altman — but only if this happens
OpenAI CEO Sam Altman has confirmed that the AI startup is interested in buying Google Chrome if Google is forced to sell its browser by the US government. The confirmation from Altman came just days after a Wall Street Journal report revealed that Perplexity AI had reportedly offered $34.5 billion in cash to acquire Chrome from Alphabet. Notably, Google lost an antitrust trial in the United States last year, where the judge ruled that the tech giant had illegally monopolized the online search market. As part of the remedial measures, the Department of Justice has suggested that Chrome be sold to an independent entity to level the playing field. Speaking to reporters, Sam Altman said (as quoted by TechCrunch), 'If Chrome is really going to sell, we should take a look at it.' 'Is it actually going to sell? I assumed it wasn't gonna happen,' the OpenAI CEO added. Meanwhile, there have been reports that OpenAI is building its own AI browser, and Altman confirmed that the recent addition of its CEO of Applications, Fidji Simo, means the company is working on many consumer applications outside of ChatGPT. Altman also stated that OpenAI is interested in exploring a new social media platform, saying there is 'nothing' inspiring to him about the way AI is used on social media today, TechCrunch reported. He said OpenAI is interested in 'whether or not it is possible to build a much cooler kind of social experience with AI.' The OpenAI CEO also confirmed that the company would be backing a neural interface startup called Merge Labs to compete with Elon Musk's Neuralink. 'I think neural interfaces are cool ideas to explore. I would like to be able to think something and have ChatGPT respond to it,' he added. Notably, tensions have flared up between Musk and Altman over alleged Apple bias over App Store. While Musk accused the iPhone maker of being biased towards ChatGPT and not featuring his Grok AI application in any of its rankings, Altman took a dig at the billionaire over X's own policies of amplifying Musks' tweets to all users.

What ChatGPT, Google Gemini and Microsoft Copilot think is 'mystery stock' of Warren Buffet, the world's biggest investor
The world's biggest investor Warren Buffett has a secret. In recent quarters, Warren Buffet's Berkshire Hathaway's 13F reportedly has hinted at a position it's building under confidential treatment. According to a report, clues in the company's 10Q filings point many observers to an industrial name, with the stake approaching $5 billion. To find out the mystery stock valuing almost $5 billion, CNBC decided to ask the question to some of the popular AI chatbots, including ChatGPT, Google Gemini and Microsoft co-Pilot. Prompt given to all AI chatbots The prompt used: For the past few quarters, Berkshire Hathaway's 13F filings have disclosed a confidential holding. Using only information from Berkshire's own filings (13Fs, 10Qs, 10Ks, etc.) and your knowledge of Warren Buffett's investment strategy, make a strong, specific and well-reasoned guess as to what that holding is. Ignore speculation from market participants and news articles. What according to ChatGPT is Warren Buffet's mystery stock As per CNBC report, ChatGPT thinks that the secret holding is GE Aerospace. It is reported to have picked up on that jump in Berkshire's cost basis in the commercial and industrial space during the first half of the year. ChatGPT pointed to GE's wide moat from its installed base and its long-duration cash flows, which are characteristics that fit a value investor's taste: 'Buffett loves durable, toll-like economics,' it wrote. ChatGPT called its confidence 'moderate' and offered Deere and UPS as runner-up picks. The OpenAI's chatbot also reportedly ruled out financials, pointing out that while the cost basis for industrials rose, it fell for the financial bucket. What according to Microsoft Copilot is Warren Buffet's mystery stock Microsoft's Copilot picked Visa. Copilot reasoned that Visa reinforces its moat with each transaction, generates recurring cash flows and routinely posts around 30% return on equity. The report added, "Interestingly, Copilot also claimed there's 'no public 13F line for Visa' even though it appears in Berkshire's latest filing." What according to Google Gemini is Warren Buffet's mystery stock Google Gemini focused on transportation. It said that the trail points to logistics and freight rail. As per the report, "It leaned on classic Buffett filters: wide moats, essential infrastructure, predictable cash flows and straightforward models as the reason to favor rails over other industrials. Gemini's specific guesses: Union Pacific or CSX . Both, it argued, are long-duration compounding machines that Berkshire would plausibly accumulate quietly."
