How ChatGPT works

ChatGPT is a large language model (LLM) — a type of artificial intelligence trained on enormous quantities of text to predict what words should come next in a sequence. The model was trained on a dataset estimated at hundreds of billions of words from the internet, books, academic papers and other sources. Unlike earlier AI systems that were trained for specific tasks, large language models develop broad capabilities — writing, reasoning, coding, translation — as emergent properties of their scale. ChatGPT was then refined using Reinforcement Learning from Human Feedback (RLHF), in which human trainers rated the quality of responses and the model was adjusted to produce more highly rated outputs. This is why ChatGPT feels helpful and conversational rather than robotic.

The economic impact of generative AI

The economic implications of generative AI — the category that ChatGPT launched into mainstream awareness — are still being understood. Goldman Sachs estimated in 2023 that generative AI could eventually automate tasks equivalent to 300 million full-time jobs globally. McKinsey suggested it could add $2.6-4.4 trillion annually to the global economy through productivity gains. In practice, the near-term impact has been most visible in specific professions: copywriting, coding, customer service, legal research, medical note-taking and image generation have all been substantially affected. Venture capital investment in AI companies exceeded $50 billion in 2023, making it the most funded technology sector of the decade.

About ChatGPT Launched

ChatGPT was launched by OpenAI on 30 November 2022, and within five days had accumulated one million users — a milestone that had taken Netflix 3.5 years, Facebook 10 months and Instagram 2.5 months to reach. Within two months, it had 100 million active users, making it the fastest-growing consumer application in history. The launch marked a turning point in public awareness of artificial intelligence that fundamentally altered the technology industry, educational institutions, professional practice and public discourse about the future of human work.

ChatGPT was built on OpenAI's GPT-3.5 large language model, refined through a process called Reinforcement Learning from Human Feedback (RLHF). For the first time, a general-purpose AI system was capable of engaging in sustained, coherent, contextually aware conversation on virtually any topic — writing essays, explaining scientific concepts, debugging code, generating creative writing, translating languages and reasoning through complex problems.

The response was immediate and seismic. Educators debated whether essays still had meaning. Lawyers, doctors, accountants, copywriters and programmers grappled with what the technology meant for their professions. Google declared a "code red" internal emergency, fearing disruption to its core search business. Microsoft announced a $10 billion investment in OpenAI and integrated AI capabilities across its product suite. Hundreds of AI startups were founded within months.

GPT-4, released in March 2023, significantly improved on its predecessor, scoring in the top percentile on the bar exam, the GRE and numerous professional certifications. The subsequent proliferation of AI tools — Claude, Gemini, Llama, Mistral and dozens of others — established generative AI as the defining technological development of the 2020s. The ChatGPT launch is viewed as the moment artificial intelligence ceased to be an abstract future concern and became an immediate present reality.
