What does GPT in ChatGPT stand for?
But behind the buzz, many people still wonder: what exactly does 'GPT' mean, and how does this technology work? Let's break it down in simple terms.
GPT
:
Generative Pre-trained Transformer
The full form of GPT is Generative Pre-trained Transformer, which may sound technical at first. Generative means the system creates new responses on its own, rather than just selecting from pre-written answers. Pre-trained refers to the extensive learning it underwent by studying a vast amount of text before interacting with users.
Transformer is the advanced technology that helps it understand and make sense of human language.
Together, these elements allow ChatGPT to have conversations that feel natural and human-like.
What does "generative" mean?
Simply put, it means ChatGPT writes its own responses. Earlier chatbots worked off scripts– they could only respond using canned replies. ChatGPT, however, doesn't follow a script. You can ask it to explain a topic, create a poem, or summarize a book, and it will come up with a brand-new answer on the spot.
What's "pre-trained" all about?
Before the tool was made available to the public, it went through an intense training phase. During this time, it was fed vast amounts of text– from books, websites, Wikipedia, news stories, and more. This gave it a broad understanding of how language works and what kind of responses make sense.
"Transformer" – The technology behind it
The 'transformer' refers to the core design that powers GPT. Introduced in 2017, this technology enables the AI to understand not just individual words but also the relationships between them throughout a sentence.
This helps the AI grasp context more effectively and respond in a clear and logical way.
Who Created GPT and When?
GPT technology was created by
OpenAI
, a research company in the United States. OpenAI was started in 2015 by a group of tech innovators and scientists, including Elon Musk,
Sam Altman
, Greg Brockman, and Ilya Sutskever. Although Musk later stepped away, Sam Altman remains the CEO and leads the company today.
GPT began with its first version, GPT-1, released in 2018. The next year, GPT-2 brought significant improvements. In 2020, GPT-3 arrived, offering more advanced and human-like responses. ChatGPT was launched in November 2022, making this technology easy to use through a chat interface. Since then, newer versions like GPT-4 and GPT-4o have added more capabilities, including understanding images and sometimes sounds.

OpenAI CEO admits he is ‘scared' of using AI
New Delhi: OpenAI CEO Sam Altman recently admitted that is scared to use 'certain AI stuff' sometimes. Speaking at one of the episodes of Theo Von's podcast 'This Past Weekend', Altman said: 'I get scared sometimes to use certain AI stuff, because I don't know how much personal information I want to put in, because I don't know who's going to have it.' Sam Altman was responding to Von's question on the fast pace of AI development, 'Do you think there should be kind of like a slowing things down?' During the conversation, the OpenAI CEO compared the current competition among AI companies as an 'intense' race not only for commercial domination, but as tool that will echo for generations. He further stated that ChatGPT-maker OpenAI does not move quickly, someone else will, adding that fate of AI could slip out of hands of those most mindful about its social consequences. During the podcast, Altman acknowledged how uncertain the human future is. 'I think all of human history suggests we find a way to put ourselves at the centre of the story and feel really good about it … Even in a world where AI is doing all of this stuff that humans used to do, we are going to find a way in our own telling of the story to feel like the main characters,' he said. Sam Altman also addressed the fear of certain jobs becoming obsolete because of AI. 'How will people survive?' host Von asked. To this, Sam Altman replied: 'AI will create possibilities for individuals to pursue more creative, philosophical, or interpersonal goals.' He said that when everyone can get instant help and knowledge through AI, people can rethink what it means to contribute to society. However, he warned that the shift could be very difficult for those who lose their jobs in the short term.

Elon Musk and Tesla's $30 trillion AI supersonic tsunami
Tesla shareholders are used to volatility. Shares dipped 8% on Thursday after Tesla reported second-quarter earnings. Shares bounced about 4% on Friday. Coming into the week of trading, Tesla stock was down 22% year to date and up about 44% over the past 12 months. Tesla CEO Elon Musk offered some pretty eye-popping aspirations for the company during remarks on Saturday. Musk made a virtual appearance at the Tesla Owners of Silicon Valley 2025 'Takeover" party in San Mateo, Calif. The group is, essentially, a fan club and community for Tesla and Musk enthusiasts. Its Takeover event draws attendees from all over the world, according to organizers. The headline from the event might just have been an admittedly aspirational comment about $30 trillion a year in humanoid robot revenue. Tesla is using its artificial intelligence and manufacturing capabilities to build its Optimus humanoid robots. Version three of 'Optimus is the right design to go to volume production," said Musk. Tesla plans to make a few hundred of those by the end of 2025. Originally, Tesla planned to have a few thousand, but the new design slowed things down a little. Tesla still plans to ramp production higher in 2026. Tesla is betting big on AI, using it for robots and to train its self-driving cars. Robots are 'probably the world's biggest product…There's a market for 20 billion robots," said Musk. 'Hypothetically, if Tesla was making one billion of these a year…maybe on the order of $30,000, I'm just guessing here, that's $30 trillion in revenue." It's an incredible prediction. 'Long way to go between here and making one billion robots a year," added Musk. There isn't a significant market for humanoid robots yet. Nvidia CEO Jensen Huang has said that robots can become the world's largest market. (Housing, consumer electronics, and cars are three of the largest today.) The world spends 'what $50 trillion on human labor a year now?" says Futurum chief market strategist Shay Boloor. Useful robots are 'pretty disruptive if you can conquer it." Musk, for his part, doesn't fear the labor disruption, believing it will end up creating an age of abundance with hard labor essentially eliminated. 'I've never seen any technology advance as fast as AI," said Musk, describing it as a supersonic tsunami. It's all pie in the sky for now, but quite a vision of the future. Investors should pay attention to events like the 'Takeover." It's almost like a Wall Street event for the EV maker. Tesla is more of a retail stock than the megacap companies. Smaller retail investors hold more than 40% of the shares available for trading, according to Bloomberg. The average for the rest of the Magnificent Seven is closer to 25%. Whether the interview will move Tesla's stock on Monday is anyone's guess. Shares dipped 8% on Thursday after Tesla reported second-quarter earnings on Wednesday evening. Shares bounced about 4% on Friday. Coming into the week of trading, Tesla stock was down 22% year to date and up about 44% over the past 12 months. Shares are trading for about 180 times estimated 2025 earnings. That's the second-highest PE ratio in the S&P 500, according to Bloomberg, trailing only Palantir Technologies. That valuation indicates that, to some extent, investors are as optimistic about the future. Write to Al Root at
