OpenAI maintains and updates the ChatGPT model, so individual users usually don’t have to take any action to “update” to a newer version.
If you’re using the API, updates may be released from time to time. OpenAI will clearly communicate any updates or changes through the OpenAI newsletter, in API documentation, or via official communications.
If there’s any action needed on your part, the steps would typically involve updating your API calls in your code to match any changes that may have been made in the newer version of the API. For more precise guidance, refer to the specific instructions from OpenAI.
If you’re using the chat.openai.com or apps, updates should be automatic. No action is required on your part once a new version is released.
