OpenAI Major Update for ChatGPT: Function call & Improved

On June 13, OpenAI suddenly released a major update for ChatGPT. The main updates include:

  1. Added function call feature in Chat Completions API
  2. Improved GPT-4 and GPT-3.5-turbo versions
  3. Updated the 16k context version of GPT-3.5-turbo
  4. Reduced the cost of embedded models by 75%
  5. Reduced the input tokens cost of GPT-3.5-turbo by 25%
  6. Announced the deprecation schedule for GPT-3.5-turbo-0301 and GPT-4-0314 models

OpenAI also announced that they would invite more people to try GPT-4 in the coming weeks until the waitlist is entirely removed.

What is a function call?

Developers can now describe functions to the GPT model, allowing the model to intelligently choose to output a JSON object containing parameters to call these functions.

In simpler terms, GPT will know when it needs to use external tools to solve a problem. It eliminates the need for developers to describe complex prompts and further reduces the likelihood of errors.


When you ask ChatGPT, “What’s the weather like in Boston?” Your question will be interpreted by the model as calling a third-party weather API. It will retrieve relevant data and output an accurate answer.

OpenAI provides a standardized interface for calling, giving developers greater flexibility when developing GPT-based applications.

New models

OpenAI has released the improved models GPT-4-0613 and gpt-3.5-turbo-0613. Both support the function call feature.

OpenAI has also released the gpt-3.5-turbo-16k model, supporting a context length of 16,000 tokens. Four times larger than the current GPT-3.5-turbo.

ChatGPT’s inability to input long text has always been a criticized issue. Now, with the gpt-3.5-turbo-16k model, you can input up to 20 pages of text. That allows ChatGPT to read long documents and papers directly.

The gpt-3.5-turbo-16k provides more value without extra cost. Although the text volume is four times larger, the price is only twice that of GPT-3.5-turbo.

OpenAI also announced that they would further reduce the cost of running models. For example, the input tokens cost of GPT-3.5-turbo has been reduced by 25%. That means you can process approximately 700 pages of documents per dollar. For more details check here!
