What is ChatGPT?

ChatGPT is the latest innovation from OpenAI. It is a model trained using Reinforcement Learning from Human Feedback to interact in a conversational way. It is fine-tuned from a model in the GPT-3.5 series, which finished training in early 2022.

How does it work?

ChatGPT is designed to provide users with an intuitive and natural conversation partner. It uses a range of features, including natural language understanding, context-aware response generation, and natural language generation. This makes it capable of:

  • responding to questions,
  • carrying out tasks,
  • providing helpful guidance.

Use cases

ChatGPT is designed to be used in a variety of ways. It can be used as a research consultant, brainstorming partner or a writing assistant. It can also be helpful in providing personalized guidance during online shopping or even for entertainment.

By far the best way to really understand how it works is to try it out. If you need some more inspiration, check out these mind-blowing examples shared on Twitter:


The OpenAI announcement blog post lists some limitations of the model including:

  • plausible-sounding but incorrect answers,
  • overusing certain phrases,
  • being sensitive to tweaks to the input phrasing.

Another interesting point was raised in a tweet by Paul Graham, the founder of Y Combinator. Given enough examples, large language models can be really good at imitating experts or producing solutions that seem very convincing. However, what is the path that takes us from impressive demos generating really good drafts to actual business products that can be truly relied upon? We explored this subject in our previous blog post.

How can I start using ChatGPT in my business?

ChatGPT will soon likely be available via API like other OpenAI models. How can you implement a large language model in your business? That’s what we’ve become experts in at Quickchat AI over the past few years.

The Quickchat AI platform allows you to build your custom conversational AI experience on top of the best large language models like GPT-3. by customizing your AI’s:

  1. Personality (the style of conversation)

  2. Knowledge Base (what your AI knows during the conversation)

  3. Integrations (interact with any internal or external system from within the conversation)

Our customers (including Robotics companies, law firms, startups and large organisations) implement Quickchat AI as a conversational interface to their products or as an AI Expert system to operate internally or externally. If you would like to discuss how our technology could be implemented for your use case, please get in touch.
