The input text passes through tokenization, breaking it down into smaller units like words or subwords. Each token is then assigned a numerical value, creating a sequence of tokens that the model can analyze.

• Positional Encoding

Positional encoding is incorporated to convey the positional information of tokens within a sequence. This assists the model in understanding the sequential order of words in a sentence.

• Model Layers

Multiple layers in the model employ self-attention mechanisms to refine input understanding, considering the context of each token in relation to others.

• Training Objectives

In pre-training, the model predicts the next word based on the preceding context, facilitating unsupervised learning to grasp grammar, semantics, and general knowledge.

• Parameter Fine-Tuning

After pre-training, the model undergoes fine-tuning through supervised learning on labeled datasets for tasks such as translation, summarization, or question-answering to enhance performance.

• Prompt Handling

In ChatGPT, users input prompts to receive responses. The model then generates outputs based on learned patterns and context, a skill known as GPT-3 prompt engineering.

• Sampling and Output Generation

The model produces responses using sampling methods like temperature-based sampling. Higher temperatures yield more random outputs, while lower temperatures result in more deterministic responses.

• Post-processing

After generation, the output undergoes post-processing to convert numerical tokens to readable text, ensuring coherence and proper formatting in the final output.

• User Interaction Loop

The repetitive process involves user feedback, and refining the model’s responses. Fine-tuning based on this feedback is essential for improving the relevance and coherence of generated responses.

• Deployment

Once trained and fine-tuned, ChatGPT can be deployed for diverse applications like chatbots and content generation. It engages in conversations and delivers helpful outputs.
