What is ChatGPT?

An AI chatbot created by OpenAI that can understand and generate human-like text, answer questions, write content, and assist with various tasks through conversation.

ChatGPT is an AI chatbot developed by OpenAI, launched in November 2022. It can engage in natural conversations, answer questions, write various types of content, help with coding, and assist with many text-based tasks.

How ChatGPT Works

ChatGPT is built on GPT (Generative Pre-trained Transformer) technology. It:

1. Was trained on vast amounts of text from the internet

2. Learned patterns in how humans communicate

3. Predicts what text should come next based on the input it receives

4. Uses reinforcement learning from human feedback (RLHF) for better responses

Versions

GPT-3.5

The free version of ChatGPT. Capable but less sophisticated than GPT-4.

GPT-4

Available with ChatGPT Plus ($20/month). More capable, fewer errors, handles complex tasks better.

GPT-4 Turbo / GPT-4o

Latest iterations with larger context windows and improved capabilities.

    • Limitations

  • Knowledge cutoff date (doesn't know recent events)
  • Can generate incorrect information confidently ("hallucinations")
  • No access to the internet (in basic versions)
  • Cannot learn from your conversations (in most modes)
