Chat-GPT - AI Features, Pricing & Use Cases

ChatGPT is an innovative artificial intelligence tool that has been trained to interact conversationally, making it suited for answering follow-up questions, challenging incorrect premises, and even refusing inappropriate requests. It has been trained through Reinforcement Learning from Human Feedback (RLHF), using human AI trainers to result in highly refined responses.

This AI model is fine-tuned from the GPT-3.5 series, trained on an Azure AI supercomputing infrastructure. OpenAI has also introduced GPT-4, which surpasses GPT-3.5 in reasoning capabilities, creativity, collaboration potential, and its capacity to handle longer contexts. GPT-4 also has the ability to process visual inputs, further enhancing its versatility for diverse applications.

Notable advancements in GPT-4 include its application in enhancing language learning experiences on Duolingo, streamlining user experiences on Stripe, organizing vast knowledge bases for Morgan Stanley, exploring educational potentials on Khan Academy, and even in preserving the Icelandic language for Iceland.

It should be noted that while ChatGPT is a powerful AI tool, it presents certain limitations and challenges. For instance, it occasionally produces plausible-sounding but incorrect or nonsensical answers, traces of bias in its outputs, and sensitivity to input phrasing. Additionally, while safety measures have been implemented to help the model refuse inappropriate requests, it may occasionally respond to harmful instructions. For this reason, OpenAI encourages continuous user feedback and has even established the ChatGPT Feedback Contest which rewards useful feedback with API credits.

Overall, ChatGPT, and its sibling model InstructGPT, represent significant advancements in AI interaction and functionality, deriving lessons from previous models like GPT-3 and Codex to ensure increasingly safe and useful AI systems. OpenAI continues to make strides in the AI domain, with ChatGPT and its newer GPT-4 model at the forefront of these developments.


  • Interactive Dialogue Design: ChatGPT is designed to interact conversationally. It can answer follow-up questions, admit mistakes, challenge incorrect premises, and reject inappropriate requests, providing a more communicative and interactive AI experience.
  • Reinforcement Learning from Human Feedback (RLHF): ChatGPT uses RLHF for training. AI trainers play both user and AI roles in conversations, with model-written suggestions to aid their responses. The resulting dialogue dataset used for training improves the model's conversation capabilities.
  • Advanced Infrastructure: ChatGPT is fine-tuned from a GPT-3.5 series model and trained on Azure AI's supercomputing infrastructure. It was completed in early 2022, ensuring modern and up-to-date AI performance.
  • Advanced Reasoning and Creativity in GPT-4: GPT-4 surpasses its predecessor in reasoning capabilities, performing better in complex tasks. It is also enhanced in generating and refining creative content, such as songs and screenplays, and can better handle longer context management.
  • Visual Input Capability: GPT-4 is equipped to process visual inputs, substantially increasing its usability in various applications and increasing interaction possibilities.
  • Safety Measures and Improvement: OpenAI has spent six months making GPT-4 safer and more aligned, with it being 82% less likely to respond to requests for disallowed content and 40% more likely to produce factual responses compared to GPT-3.5. The model uses extensive human feedback and continuous improvements based on real-world use.
  • Limitations and Ongoing Development: OpenAI acknowledges its limits, such as occasionally generating plausible-sounding but incorrect or nonsensical answers, sensitivity to input phrasing, and verbosity. Efforts are ongoing to address these challenges and improve model performance.
  • Iterative Deployment and User Feedback: The release of ChatGPT is part of OpenAIโ€™s iterative deployment strategy to create increasingly safe and useful AI systems. User feedback is highly encouraged to rectify problematic model outputs and improve external content filtering.


    • Free Version: ChatGPT offers a research preview version which is free for use by those who sign up on the ChatGPT website. This allows users to experience the tool's conversational and problem-solving capabilities without cost.
    • ChatGPT Plus: For an advanced user experience, ChatGPT presents ChatGPT Plus, a subscription-based service costing $20 per month. Subscribers gain priority access, faster load times, and the opportunity to avail new features and updates ahead of other users. Moreover, subscribers can explore the offerings of GPT-4, OpenAI's most advanced and creative model.
    • App Availability: For increased accessibility and convenience, ChatGPT has an official app available for free download on iOS devices.
