The ins-and-outs of creating and using a CustomGPT
CustomGPTs are reusable, specialized “digital teammates” you design for a specific purpose. Unlike ad‑hoc personas inside a single chat, CustomGPTs bundle together instructions, knowledge, and behaviors into a named assistant you can call on anytime, such as “Teacher’s Assistant (TA) Iris.” CustomGPTs are especially useful for work you repeat often and want to perform consistently, at a high level, across many chats and projects.
How to create a customGPT
Prompting Best Practices
A well rounded CustomGPT should contain each of the following elements:
Capability limits
You cannot perform deep research or schedule an action from within a customGPT.
Memory
Memory is siloed to the customGPT’s knowledge and instructions.
Sharing
When you share a Custom GPT:
Others can use it, but cannot edit your original configuration by default. You can give editing ability to specific users.
Updates you make apply only from that point forward; previously generated outputs do not retroactively change. The updates apply to the shared versions of the customGPT as well.
