Launched in 2022, ChatGPT is a revolutionary AI tool developed by OpenAI that has transformed how we write, code, research, and interact with technology. This guide explores its launch history, working mechanism, versions, pricing plans, uses, and future.
Origin and Ownership
ChatGPT was introduced on November 30, 2022 by OpenAI — an AI research company founded in 2015. Its mission is to ensure that artificial general intelligence (AGI) benefits all of humanity. Sam Altman, the current CEO, leads OpenAI’s mission of democratizing AI. Elon Musk was also a founding member but stepped away from the company’s operations early on. Since its launch, ChatGPT has become a global tool used by millions of users daily.
Version History and Evolution
- GPT‑3.5 (2022): Publicly released with ChatGPT, capable of human-like responses in conversational text.
- GPT‑4 (March 2023): Introduced advanced reasoning, math-solving, and coding capabilities.
- GPT‑4o (Omni) – May 2024: Added full multimodal support — understanding and responding to text, images, voice, and video in real-time.
- GPT‑4.1 and GPT‑4.5 (2025): Provided improved memory, reduced latency, and support for more languages and file types.
- Mini Models (GPT‑o3, o4-mini): Designed for fast mobile access and embedded systems with lightweight response engines.
How ChatGPT Works
ChatGPT is powered by a large language model (LLM) trained on diverse data including books, websites, articles, conversations, and code repositories. It uses a neural network known as a transformer, which processes text through layers of learned patterns.
GPT-4o takes this further by processing multimodal inputs. This means it can analyze an image, listen to a voice clip, or even respond to video-based interactions. These abilities are powered by Microsoft Azure’s AI supercomputing infrastructure using thousands of high-performance GPUs.
Prompting Best Practices
Prompts are how users interact with ChatGPT. To get the best results:
- Use specific instructions: e.g., “Write a formal email to a client about project delay.”
- Set a role: “Act as a software engineer explaining Python to beginners.”
- Break into steps: “First explain what HTML is, then provide a code example.”
- Iterate and refine: If the first answer isn’t great, ask for an improved or shorter version.
