What is GPT and How Does it Work in ChatGPT?
AI chatbots, like ChatGPT, have become increasingly popular due to their ability to write like humans, from college essays to computer code. The technology behind these chatbots is powered by large language models, specifically the family of Generative Pre-trained Transformers (GPT). But what exactly does GPT stand for in ChatGPT?
GPT Definition
GPT stands for Generative Pre-trained Transformer. It refers to the natural language processing technology that powers AI chatbots such as ChatGPT. Bing Chat, for instance, uses the more advanced GPT-4 model, while ChatGPT relies on GPT-3.5.
ChatGPT Plus vs Free Version
The GPT-3 model was first released in 2020 and is used in the free version of ChatGPT. However, for those who pay for ChatGPT Plus, they also gain access to the more advanced GPT-4 model.
GPT-4 Model
The latest release of GPT, GPT-4, has improved significantly in terms of accuracy and knowledge. Not only can it understand different kinds of input, but it can also comprehend images and graphs, not just text-based prompts.
Comparison with Google
The technology behind ChatGPT is different from Google. While Google has its own large language model called LaMDA, it does not use the GPT family for its products.
Fine-tuning the GPT Model
ChatGPT's GPT-3.5 language model has been fine-tuned with the help of human workers to respond in a friendly and conversational manner. However, developers can still use the base GPT-3 model for their own projects and fine-tune it according to their needs.
Accessing OpenAI's Playground
If you're interested in seeing what OpenAI's bare language model looks like, you can access GPT-3 from any web browser. OpenAI's Playground is customizable according to your needs with a Temperature slider that adjusts the randomness of responses, a repetition penalty, and a maximum length slider.
Conclusion
In conclusion, GPT in ChatGPT refers to the natural language processing technology that powers the chatbot. The GPT family of models, specifically GPT-3.5 and GPT-4, have significantly improved accuracy and can understand different types of input.
