Difference between GPT-3.5 and GPT-4

ChatGPT, GPT-3.5, and GPT-4 are all large language models (LLMs) developed by OpenAI, but they have distinct characteristics and capabilities:

Difference between GPT-3.5 and GPT-4

1. Model Parameters:
   • GPT-3.5: It has 175 billion parameters.
   • GPT-4: The latest version, GPT-4, has even more parameters, although the exact number is not specified in the provided information.
2. Capabilities:
   • GPT-3.5:
     • Processes plain text input and generates natural language text and code output.
     • Doesn’t handle images or visual inputs.
     • Faster in generating responses.
     • No hourly prompt restrictions.
   • GPT-4:
     • Can accept visual inputs, such as images of graphs or worksheets.
     • Still processes plain text input and produces natural language text and code output.
     • Improved accuracy and fewer factual errors.
     • Comes with hourly prompt restrictions.
3. Access:
   • ChatGPT Plus (ChatGPT+): The paid version of ChatGPT, which uses GPT-4 technology, costs $20 per month.
   • Free Version: If you’re using the free version of ChatGPT, you’ll still be using GPT-3.5 for now.
