OpenAI unveils conversational AI chatbot ChatGPT

- Advertisment -

OpenAI has released a new conversational AI chatbot called ChatGPT that responds to user input in a conversational fashion.

ChatGPT, short for chat-based generative pre-trained transformer, employs natural language processing (NLP).  According to OpenAI, ChatGPT may respond to follow-up questions, admit mistakes, dispute faulty premises, and reject unsuitable requests thanks to the conversational style.

ChatGPT is a sibling model of InstructGPT, which is trained to respond to a prompt with a thorough response.

This model was trained by OpenAI using Reinforcement Learning from Human Feedback (RLHF), utilising the same approaches as InstructGPT but with minor modifications in the data gathering arrangement. OpenAI used supervised fine-tuning to train an initial model: human AI trainers offered interactions in which they played both sides—the user and an AI assistant. They provided the trainers with model-written ideas to assist them in composing their responses.

During its research preview phase, OpenAI introduced the new technology for free. Users can try it at https://chat.openai.com/. ChatGPT is easy to use as users just have to type their queries, and it will provide an answer. 

When officially launched, it is said that ChatGPT can be used for various industries such as customer service, virtual assistant, and language translation. 

As a beginner, here are some tips on how to use ChatGPT or other conversational AI technology:

  • Start with simple queries. It is preferable to begin with short, easy queries while utilising ChatGPT for the first time. This will help ChatGPT understand your intentions and respond appropriately. Users may, for example, ask ChatGPT for information on a specific topic or to do a simple job like creating a reminder or delivering a weather prediction.
  • Be clear and concise. It is critical to use clear and concise language when communicating with ChatGPT. Use simple, everyday words and phrases such as what you would use in a simple conversation with a human instead of complex sentences or jargon. This will make it easier for ChatGPT to understand your input and offer a more accurate response.
  • Be patient. ChatGPT, like all AI technology, is not without flaws. It may not always understand or respond to your questions, and it may take some time to learn and adapt to your preferences. As a result, when using ChatGPT, it is critical to be patient and understanding and to provide feedback and corrections as needed.
  • Use available resources. Suppose this is your first time using ChatGPT, you should take advantage of any available resources, such as user guides or tutorials, to learn more about the technology and how to use it effectively. This will assist you in making the most of ChatGPT and its capabilities.

As it is still in the research preview stage, OpenAI has listed some of ChatGPT’s limitations. They are as follows:

  • ChatGPT occasionally writes plausible-sounding but incorrect or illogical responses. Fixing this problem is difficult because: (1) there is currently no source of truth during RL training; (2) training the model to be more cautious causes it to decline questions that it can correctly answer; and (3) supervised training misleads the model because the ideal answer depends on what the model knows rather than what the human demonstrator knows.
  • ChatGPT is sensitive to changes in input phrasing or multiple attempts at the same prompt. For example, given one phrasing of a question, the model can claim ignorance, but given a slight rephrasing, it can accurately answer.
  • The model is frequently overly verbose and overuses specific phrases, such as repeating that it is an OpenAI-trained language model. These problems arise due to biases in the training data (trainers prefer lengthier answers that appear more thorough) and well-known over-optimisation concerns.
  • When a user submits an uncertain query, the model should ask clarifying questions. Instead, our current models frequently infer what the user meant.
  • While OpenAI has made efforts to prevent the model from responding to inappropriate requests, it will occasionally respond to harmful instructions or exhibit biased behaviour. According to OpenAI, it is utilising the Moderation API to warn or ban specific sorts of hazardous content, although they expect it to have some false negatives and positives for now. The company said they’re eager to collect user feedback to aid its ongoing work to improve this system.
