Optimizing Language Models for Dialogue

About ChatGPT

OpenAI trained a model called ChatGPT which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response.

Example use cases:

ChatGPT growth

  • It took NetFlix 3.5 years to reach 1 million users.
  • It took Facebook 10 months to reach 1 million users
  • It took Instagram 2.5 months to reach 1 million users
  • It took Spotify 5 months to reach 1 million users

After one week of launching, ChatGPT gained 1 million users. While GPT-3 is the more powerful Large Language Model (LLM) of the two, ChatGPT is better suited for chatbot applications and is faster and more efficient than GPT-3.

ChatGPT passes exams and tests

ChatGPT is smart enough to pass prestigious graduate-level exams:

How to download the ChatGPT app

ChatGPT is available online and doesn't need to be downloaded.

ChatGPT limitations

ChatGPT's knowledge is also pretty much restricted to things it learned before 2021. However, it is undeniable that the AI Chatbot is the smartest one ever seen by the public. And it isn't even OpenAI's best AI model, which would be GPT-4, releasing in 2023 or so.

The current limitations of the dominant large language models and their derivatives (e.g., ChatGPT) are well known and are acknowledged by their developers (see here for ChatGPT/LLM errors tracker). There is no doubt that they will be further improved—and that we will continue to be surprised by their capabilities.

But there is also another hidden problem lurking within ChatGPT: That is, it quickly spits out eloquent, confident responses that often sound plausible and true even if they are not.


ChatGPT pricing

Is ChatGPT free?

Although ChatGPT is free to use, Sam Altman, The head of OpenAI, stated that cost per chat was “probably single-digits cents,” leading to a discourse about the future of monetizing the platform.

Update 2022-01-20

ChatGPT professional, the premium version, is now priced at $42 per month.
