Demystifying ChatGPT: A Technical Deep Dive into Its Inner Workings

Process Flow

1.??? Stage I: Input Data

i)???? Source of Data: Internet, books, articles, etc.

ii)??? Volume: 45 TB (1GB = 1 million words)

iii)?? Preprocessing: Data cleaning, tokenization, etc.

2.??? Stage I: Training on Deep Learning Algorithms

i)???? Transformer Architecture with 96 layers and 175 billion parameters

ii)??? Learns statistical patterns and relationships in the data

3.??? Stage I OUTPUT: Base GPT Model

i)???? Generative Pre-Trained Transformer Model

ii)??? Capable of sentence completion, text summarization, text generation, sentiment analysis, translation, etc.

4.??? Stage II: Instruct GPT Method

iii)?? Request and Response concept is applied

5.??? Stage II: Train Data Corpus

iv)?? Create crafted conversation data corpus using expert policy (hand-crafted rules)

v)??? Use stochastic gradient descent or other optimization algorithm

6.??? Stage II OUTPUT:

vi)?? Supervised Fine-Tuned Model

7.??? Stage III: Input

vii)? Generate alternative responses for a given request

8.??? Stage III: Ranking Method

viii)??????? Rank responses from top to bottom based on their quality

9.??? Stage III: Reward Model

ix)?? Trained using reinforcement learning

x)??? Assigns higher scores to more informative, relevant, and engaging responses by using Proximal Policy Optimization

xi)?? Uses Kullback-Leibler divergence to measure similarity to human-generated responses

10. Stage III OUTPUT:

11. ChatGPT Model

Conclusion:

It is a three-part process to train it: first, it learns how to generate text on its own, then it gets some guidance from humans, and finally, it gets feedback from real humans to get even better.

?

As AI becomes more sophisticated, the line between human and machine blurs. Is ChatGPT a glimpse into our future, where robots are not just tools but companions? Or is it a cautionary tale of a world overrun by intelligent machines?
