OpenAI DevDay: Opening keynote takeaways

OpenAI DevDay: Opening keynote takeaways



  • Now you can custom your own ChatGPT by GPT Builder with prompt, instruction, profile avatar, conversation-starting, and inductive knowledge.
  • You can share your customized chatbot on the GPT store, and earn money when people use it.
  • ChatGPT now chooses the response model automatically, no more model picker menu.


  • New model GPT-4 Turbo with 128k context length (~300 pages of a book). It's 2x token generation speed and less expensive (3x less for input tokens, 2x less for output tokens) than the current GPT-4.
  • The knowledge of GPT-4 Turbo is up to April 2023 (continuous improvement). It now supports JSON response (more output control).
  • New assistants API for Threading (now the API is aware of the conversation context, doesn't need to send from client-side anymore), Code Interpreter, Retrieva, and Function calling.
  • GPT-4 fine-tuning experimental access.
  • Copyright shield: OpenAI pays if you face legal claims around copyright infringement. This applies to generally available features of ChatGPT Enterprise and the developer platform.

New Models:

  • New DALL-E 3.
  • GPT-4 Turbo comes with vision capabilities.
  • New TTS API (with 6 unique voices) and Whisper 3 for text-to-speech are coming soon.
