Update: The custom instructions option has reportedly disappeared for some users. We’re looking into it, but in the meantime don’t be surprised if the function isn’t available to you right now.

OpenAI just launched custom instructions for ChatGPT users, so they don’t have to write the same instruction prompts to the chatbot every time they interact with it — inputs like “Write the answer under 1,000 words” or “Keep the tone of response formal.”

The company said this feature lets you “share anything you’d like ChatGPT to consider in its response.” For example, a teacher can say they are teaching fourth-grade math or a developer can specify the code language they prefer when asking for suggestions. A person can also specify their family size, so ChatGPT can give responses about meals, grocery and vacation planning accordingly.

While users can already specify these things while chatting with the bot, custom instructions are helpful if users need to set the same context frequently.

The instructions also work with plug-ins, making it easier for them to suggest restaurants or flights based on your location.

OpenAI noted that the feature is available for Plus plan users, but it won’t be available for people based out of the EU and the U.K. It is a beta feature for now.

Users can try out this feature on the web by clicking on their name and going to Settings > Beta features > Opt into Custom instructions. On iOS, users can access this through Settings > New Features > Turn on Custom Instructions.
