ChatGPT Turns 3 and The future of AI is here


ChatGPT officially debuted in November 2022, marking a watershed moment in the history of artificial intelligence. Its launch was significant because it introduced large language models to the broader public in a highly accessible and user-friendly format. For the first time, millions of users could directly interact with an advanced AI capable of holding meaningful conversations, generating creative content, assisting with problem-solving, and more. This democratization of AI not only accelerated awareness of its potential but also sparked widespread discussions about its implications for various industries, education, and society at large. The launch of ChatGPT in November 2022 is often credited with igniting a new wave of innovation and adoption of AI technologies, making it a pivotal moment in the AI revolution.

Now let me take you through a brief trip down memory lane to see how we arrived here.

In 1936, Alan Turing introduced the concept of a universal machine (the Turing Machine) that could simulate any algorithmic process. In 1956, John McCarthy coined the term Artificial Intelligence as we know it. The 1970s saw early research and optimism around AI, though nothing concrete emerged.

In the 1990s, AI research shifted towards machine learning and statistical approaches. A defining moment came in 1997 when IBM’s Deep Blue defeated world chess champion Garry Kasparov. This breakthrough stunned the world and showcased AI’s potential. Progress during this time also included the development of algorithms like decision trees and early neural network models.

In the 2000s, advancements in big data and neural networks accelerated the AI revolution. A major breakthrough occurred in 2014 when Google’s DeepMind program, AlphaGo, defeated professional Go players, demonstrating AI’s ability to handle complex tasks. AI also began excelling in specific domains like image and speech recognition.

In 2015, OpenAI was founded with the mission of ensuring artificial general intelligence (AGI) benefits all of humanity. The following year, in 2016, Google’s AlphaGo defeated world champion Go player Lee Sedol, a landmark achievement in AI history.

The pivotal moment for modern AI came in 2017 with the publication of the landmark paper Attention Is All You Need by researchers at Google. This introduced the Transformer model, which became the foundational architecture for natural language processing (NLP) and other AI applications. The Transformer enabled state-of-the-art performance on various NLP tasks, including translation and language modeling.

In 2018, OpenAI released the first Generative Pre-trained Transformer (GPT) model, and in 2019, GPT-2 was introduced, featuring 1.5 billion parameters. Between 2020 and 2022, OpenAI developed ChatGPT, a version of GPT-3 fine-tuned specifically for conversational use. This model demonstrated the ability to engage in dialogue, answer questions, provide recommendations, and generate content.

In 2023, OpenAI released GPT-4, an even more advanced model, pushing the boundaries of AI further. The evolution of ChatGPT continued rapidly: in 2024, OpenAI introduced GPT-4o, which added multimodal capabilities, enabling image, voice, and text processing within conversations. The model also gained a "memory" feature, allowing it to remember user details across sessions for more personalized responses.

By August 2025, ChatGPT 5 was officially launched, marking a milestone with even smarter, more conversational AI. GPT-5 included an advanced reasoning engine, better long-term contextual understanding, and multimodal abilities that expanded support for video, spatial tasks, and voice interaction. Users experienced faster, more natural conversations with AI demonstrating empathy and warmth beyond prior iterations.

Besides improving core capabilities, 2025 saw ChatGPT transform from a simple chatbot into a full AI platform integrated with apps and commerce tools. OpenAI's rollout included:

* In-chat commerce with Instant Checkout

* An Apps SDK for developers to build interactive AI applications

* Agent toolkits for autonomous workflow bots managing scheduling, transactions, and analytics

* Enhanced Codex integration for next-level code generation, debugging, and automation

The AI also gained advanced voice mode, deep research tools, and better factuality with fewer hallucinations, making it a powerful assistant for personal and enterprise use.

By late 2025, the AI landscape broadened even further. Several notable developments include:

* Anthropic’s Claude 3.5 family advancing visual reasoning and document understanding.

* Google’s Gemini 2 integrating seamlessly across YouTube, Workspace, and Android, emphasizing multimodal collaboration.

* xAI’s Grok 3 introducing real-time knowledge integration with the X platform (formerly Twitter).

* Meta’s LLaMA 3 and 3.1 releases, open-weight LLMs empowering developers worldwide.

* The rise of open-source multimodal models like Mistral and Falcon 2 trained on optimized compute-efficient architectures.

* Growing adoption of on-device AI on smartphones and laptops, enabling private, low-latency generative experiences.

* Widespread integration of AI copilots across Microsoft 365, Salesforce, and Adobe ecosystems.

What sets Generative AI apart from traditional AI is its ability to generate original content. This capability allows it to help humans make sense of vast amounts of information and create new insights. Generative AI models are trained on enormous datasets that are unfathomable to the human brain. This mix of excitement and concern positions Generative AI as one of the most disruptive technologies of our time.

Apart from ChatGPT, other valuable tools like Gemini, Grok, Claude, and many more continue to emerge. The speed of progress is breathtaking, with continual breakthroughs in understanding and applications. For example, Claude 3.5 Sonnet excels in visual reasoning tasks such as interpreting charts and accurately transcribing text from imperfect images.

A key concept behind Generative AI is Large Language Models (LLMs). LLMs are designed to understand and generate human language based on massive text corpora, learning general language patterns through tasks like predicting the next word or masked language modeling. LLMs underpin practical applications like content creation, auto-completion, and complex question answering.

Prompt engineering is critical in success with these systems: designing inputs that clearly specify desired outcomes leads to higher-quality results. The more context and examples given, the better the AI performs.

Two foundational concepts in AI are supervised learning and unsupervised learning:

* Supervised learning trains models on labeled data pairs.

* Unsupervised learning finds patterns in unlabeled data.

Both support advances in Generative AI alongside deep learning, a subset of machine learning specializing in large neural networks modeling complex patterns.

Generative AI is revolutionizing industries like software development and testing:

* Developers use AI tools like Codex to generate code snippets, automate reviews, and improve performance.

* Testing benefits from AI-driven test case creation, predictive bug detection, and enhanced continuous integration/delivery pipelines.

No discussion of AI is complete without ethical considerations:

* Bias in training data can skew model outputs.

* Hallucinations cause AI to generate false or misleading information.

* Transparency and explainability build trust.

* Data security remains paramount in AI solutions.

In a world of rapid AI disruption, continuous learning is essential. Richard Feynman’s four-step learning method remains relevant: study (focus on what you can learn), teach (teaching others helps you imbibe the learning), identify gaps (understand where your gaps are and fill them with more knowledge), and simplify (make things easy to learn and keep them simple). Books like AI Superpowers by Kai-Fu Lee and 21 Lessons for the 21st Century by Yuval Noah Harari offer valuable insights to navigate the evolving AI landscape. Harari highlights the “four C’s” — critical thinking, communication, collaboration, and creativity — as essential skills for the future.

Keeping creative muscles sharp will be key to thriving amid ongoing AI innovations.

Wish you a great journey of learning and growth in this exciting era. The views expressed here are my own and do not represent my organization.

Life is like a Test Match in Cricket

Image
I love the game of cricket. I was an avid cricket follower at least till the time Rahul Dravid retired. The five-day test match is the true test of patience. Believe it or not even after 5 days you can have a game with no result which is perplexing to some. To me the 5 days that a cricketer goes through is the same all of us go through during our work. We all get usually five days in a week to perform at our best. The only difference is while cricketers may not play test matches throughout the year or even a life we all will get easily 40 years of playing test matches week after week. With the advent of Twenty Twenty the viewership for test matches are dwindling but the drama of a test match is something that can never be replaced. Imran Khan once said to succeed in 20-20 you need a lot of talent, a little technique and not much temperament. However, for test matches you need all the other T’s in abundance. The epitome of a test match player for me is Rahul Dravid. He had an abu...

The 5 P's of Ethical Power

The book “The Power of Ethical Management” by Ken Blanchard and Norman Vincent Peale was published in 1988. The principles laid out in this book are still relevant today. It consists of information which is of timeless value and serves as a worthy reminder on ethics and its importance. I particularly liked the 5 core principles of ethical decision making mentioned in the book. Here are the 5P’s of Ethical Power Purpose  – The authors define purpose as ongoing. It is something an individual lives by. A personal mission statement of an individual can serve as the purpose. It is the vision you have for yourself and what you would like to be known for. The authors mention something called the mirror test where you look at yourself in the mirror and ask yourself if everything you are doing is aligned to your purpose. If there is anything not aligned to your purpose ignore it. I like this line  “There is no pillow as soft as a clear conscience.” Pride  – A healthy self...

7 Inspiring Lessons from Elon Musk

Image
Elon Musk is one of the greatest business icons of the 21st century. With the passing of Steve Jobs he has rightly taken the pole position in the realm of business leaders who are considered visionaries. I read the book on Elon Musk by Ashlee Vance and it is a wonderful inspiring read. Here are the lessons I gleaned.  Be in it for the long haul – Irrespective of what our aim is unless we have decided to be in it for the long haul it is very difficult for us to scale the heights that we are capable of. Elon Musk in 2008 was in dire straits. Space X and Tesla were both running out of money but the man was in it for the long haul. He didn’t care about short term setbacks. He always looked to the future with hope and was over optimistic in most cases. He set unrealistic deadlines as that’s the way he thinks.  Everything he does is fast and he is always in a hurry. He pays an obsessive attention to detail and for SpaceX he wants to reduce the cost of lau...

10 Qualities of a True Champion

Image
Champions are born but they are also made by relentless practice, clear goals, never say die attitude and a willingness to learn something new every day. I loved the book “The Way of the Champion” by Jerry Lynch. It has a lot of examples from sports but a lot of it can be applicable to us as well. Here are the lessons I gleaned. Self-acceptance : The first step in being a champion is being comfortable with who you are. Accept yourself unconditionally and remember all champions have weaknesses. Understand your strengths focusing on those while complementing your weakness are with the strengths of others. Self-definition : Define what you want to be known for. For example, you may want to be known for your discipline, passion, persistence and ask yourself every day if you are doing these things. Decide what message you want to send to your team or stakeholders. Modesty:   If you know you are a champion you don’t need to show off. You will be totally comfortable with yourself a...

The Dream is Free but the Journey Isn't

Image
I was discussing with my daughter some time back about dreams and it got me thinking that we always encourage our kids to dream big while encouraging them that they can achieve anything they want. However is that really good solid advice. I thought deeply about what do dreams signify and how can I explain to kids that you cannot achieve anything you want but you must think big while working towards your dreams. It also got me thinking that some of the adults have stopped dreaming so I really wanted to write this piece addressing what it takes to do your dreams. The word dreams project an excitement that no other word can. Dreams are a vision for your future which pulls you to wake up every morning with a smile and look forward to each day with excitement. In my opinion get excited about your life first and then you can truly wake up with a smile. Just read this wonderful article from Larsen Jensen  Positive Psychology Lessons from an Olympic Medalist and Navy SEAL . He says h...

Never ending journey of Success and Goals

The first step to understand about success is that it is not a destination but a wonderful journey that never ends. The best definition of success I have come across is by Earl Nightingale "Success is the progressive realization of a worthy ideal/goal." It is the process that’s actually exciting. Most of the times once we reach goals like getting the promotion or losing the weight we can’t keep up momentum but it is the process that actually keeps us energized. Once we achieve our goals we feel good for that moment but in order to keep that feeling ongoing we need to keep setting new goals. The important thing to remember is that goal setting is a lifelong activity and it does energize our lives. People talk a lot about dreams but there has to be a distinction between outrageous dreams and dreams that ignite. I can have a dream to be the greatest tennis player that ever lived but that dream is surely not going to be realized and it is very much outrageous. I think when we s...

Biographies can really inspire us. Imagine reading around 15 mini biographies at the same time. This is what Robert Greene has done with Mastery. This is one of the best books I have ever read and goes deep into what it takes to reach mastery in your field. I have read this book multiple times and it is a worthy addition to your library. This summary is only an appetizer and you really need to read this book in its entirety to get the full satisfaction. Yes it is not an easy read but well worth your effort. Here is a very high level review on what the book contains. Don’t separate your work from your personal life it is a sad separation since most of our time is spent at work so we can’t be miserable there. He also says masters felt a sense of destiny. For example Albert Einstein was immediately moved when his father gave him a compass when he was just 5 years old. Discover your calling. Each of us has a purpose to fulfill so discovering that is the first step towards mastery....
