OpenAI DevDay recap: GPT-4 Turbo and more

Yesterday, OpenAI held their very first DevDay and announced everything from the new GPT-4 Turbo model to an upcoming store for GPTs built with ChatGPT (think the flagship AI version of Apple’s App Store). 

GPT-4 Turbo has a mind-boggling 128k content length (Claude 2 has been the longest at 10k), updated knowledge cutoff to April 2023, and significant pricing reductions. OpenAI also announced that they’ll defend customers in copyright infringement claims. And they’re getting ready to launch the GPT Store – which allows creators to build their own AI agents with ChatGPT and get paid.

Here are some of the biggest announcements from OpenAI DevDay.

New GPT-4 Turbo model

GPT-4 Turbo has knowledge of world events up to April 2023 and a 128k context window. It can fit 300 pages (or more) of text in a single prompt. It’s also 3x cheaper for input tokens and 2x cheaper for output when compared to GPT-4. 

All paying developers can try GPT-4 Turbo by passing gpt-4-1106-preview in the API and a production-ready model is coming in the next few weeks. 

  • 128k context length (300 pages)
  • JSON mode
  • Many functions at once instead of only one at a time
  • Knowledge cutoff is now April 2023
  • GPT-4 fine-tuning experimental access program
  • GPT-4 rate limits increase (2x tokens per minute)
  • 3x cheaper than GPT-4 for input tokens
  • 2x cheaper than GPT-4 for output tokens

New modalities available in developer API

GPT-4 Turbo is now available in the developer API for testing and you can also integrate DALL·E 3 and text-to-speech (TTS).

Customer copyright shield (OpenAI will pay your legal costs)

This is a big one, especially for enterprises. AI created new and risky territory with copyright infringement, and much of the potential in AI hasn’t been worth the potential legal exposure. 

Now, OpenAI will defend its Chat GPT Enterprise customers and developer platform users by paying costs incurred and defending customers in legal claims around copyright infringement.

Here’s the new policy verbatim from OpenAI: 

“OpenAI is committed to protecting our customers with built-in copyright safeguards in our systems. Today, we’re going one step further and introducing Copyright Shield—we will now step in and defend our customers, and pay the costs incurred, if you face legal claims around copyright infringement. This applies to generally available features of ChatGPT Enterprise and our developer platform.”

GPTs (Agents) and GPT Store

GPTs are custom versions of ChatGPT that perform specific functions – everything from a creative writing coach to a tech adviser. These are essentially the new evolution of smartphone apps built with the power of AI.

  • GPT Store launches later in Nov.
  • Revenue sharing for GPT creators

With revenue sharing for GPT creators, expect to see a whole new set of AI possibilities and functions.

Assistants API w/Python Code Interpreter

Launching Assistants API is OpenAI’s first step to helping developers build agent-like experiences in their own applications. It combines Code Interpreter, retrieval, and function calling – which would allow anything from a natural language-based data analysis app to a code interpreter that writes production Python code.

  • Threading
  • State management
  • Prompt and context management (chunking text)
  • Extend capabilities
  • Retrieval
  • Code Interpreter (API can generate exportable files for you)
