1. Origins in GPT (Generative Pre-trained Transformer) AI tool updates as follows
In 2018, OpenAI introduced GPT-1, a language model based on the Transformer architecture developed by Google in 2017.
GPT-1 had 117 million parameters and could generate text, but it was still limited in coherence and depth.
2. GPT-2 – First Big Leap (2019)
GPT-2 was much larger (1.5 billion parameters) and showed surprising abilities in generating long, coherent text.
First, OpenAI did not release the entire model out of fear of misuse (fake news, spam), but eventually released it.
3. GPT-3 – Mainstreaming (2020)
GPT-3 boasted 175 billion parameters, a giant improvement.
It could write essays, respond to questions, code, and so forth.
Several companies incorporated GPT-3 into chatbots, customer support, and creative applications.
4. ChatGPT Launch (2022)
Open AI released ChatGPT, a conversational fine-tuning of GPT-3.5, in November 2022.
It went viral, gaining 1 million users within 5 days — the fastest uptake of a consumer technology product at the time.
5. GPT-4 – Smarter & Multimodal (2023)
Launched in March 2023, GPT-4 was more accurate, more creative, and able to reason.
It was able to process images (describe, interpret) and was more stable in professional applications.
Microsoft incorporated GPT-4 in Bing Chat and Office applications.
6. GPT-4 Turbo & Custom GPTs (Late 2023)
OpenAI released GPT-4 Turbo, a more affordable and faster model.
Users can make Custom GPTs based on their personality, instructions, and files.
7. GPT-5 and Beyond (2025)
GPT-5 (current model) has more reasoning, improved accuracy, enhanced memory, and accommodates advanced multimodal inputs (text, image, and coming soon audio/video).
Currently utilized in education, programming, business automation, and personal assistance.

My Review
I have been using ChatGPT for the past four years, and it has truly transformed the way I work. From drafting professional emails to creating detailed content and answering complex queries, ChatGPT has significantly sped up my tasks, saving me both time and effort. Its accuracy, adaptability, and ability to understand context make it an indispensable tool for my daily activities. I highly recommend everyone to try it at least once—you’ll be amazed at how much it can simplify your work. ChatGPT is more than just an AI tool; it’s like having a smart assistant available 24/7.
A full step-by-step use of ChatGPT as follows
1. Basics – Getting Started
What ChatGPT is:
A conversational AI that can respond to questions, write text, clarify concepts, suggest ideas, and more.
How to begin:
Sign up / Log in at chat.openai.com.
Select the model (e.g., GPT-3.5, GPT-4, GPT-5 subject to availability).
Enter your question or request in the chat box.
Press Enter and await the response.
Example beginner prompts:
“Explain photosynthesis in simple words.”
“Write me a short birthday message for my boss.”
“Translate the following sentence into French: ‘How are you today?'”
2. Intermediate – Eliciting Better Responses
ChatGPT will respond optimally when your prompts are specific, context-rich, and clear.
Tips:
Provide context: Instead of “write me an email”, ask “Write me a nice email to my landlord requesting the leaking tap be repaired.”
Define the style: Example — “Write a friendly professional email.”
Break down large tasks: Ask in steps, e.g., “First, list blog ideas. Then help me write one.”
Examples:
“Be a financial advisor and assist me in planning a budget for an individual who earns ₹60,000 monthly.”
“Break down this paragraph in bullet points.”
3. Advanced – Using ChatGPT at Work
You can turn ChatGPT into a productivity tool for:
Writing & Editing: Blog posts, resumes, product descriptions.
Learning: Explaining math, coding, history.
Coding: Debugging code, generating scripts, learning programming languages.
Business work: Creating contracts, proposals, marketing writing.
Handling data: Interpreting CSV files (using ChatGPT Plus or code interpreter mode).
Advanced prompts:
“You are a master Python coder. Create a script to scrape Amazon product prices.”
“Summarize the main points from this PDF and produce a 5-slide PowerPoint.”
4. Pro Features (ChatGPT Plus / Advanced Tools)
If you have ChatGPT Plus or above:
GPT-4/GPT-5 – Wiser, more precise.
Code Interpreter / Advanced Data Analysis (ADA) – Will be able to calculate, data analysis, create charts.
Image Input – Upload a pic and query regarding the same.
Custom GPTs – Make your own AI with custom commands.
File Uploads – Provide it with documents, spreadsheets, and request it to work on the same.
Example:
Upload sales spreadsheet → Request: “Create me a graph of monthly revenues and identify trends.”
5. Pro Tips for Best Results
Tell ChatGPT who it should be: “Act as a travel guide” or “You are a professional legal advisor.”
Iterate: If the answer isn’t perfect, say “Make it shorter,” “Add examples,” or “Rewrite in simpler words.”
Use follow-up questions – It remembers the conversation context.
Ask for formats: Bullet points, tables, step-by-step guides.
Check facts – It can make mistakes, so verify important info.
