Not a great comparison, custom GPTs use plugins or function calling similar to how they use code interpreter. You can't really compare them because plugins or functions are a tool that GPTs use in addition to other features. The advantage a custom GPT has is it is easy to set up but it comes with big disadvantages such as having to use their RAG system which is very opaque and only being able to use one system message. Building with the assistant API can be far superior but requires a lot more effort and skill in building your own APIs.
