My best use case so far has been to make GPTs for a particular tech stack specific to a project I might be working on for a couple months. Saves a lot of re-prompting to build context. Seems like they understand this type of use case as valuable since they allowed internal-facing GPTs you can share in the Teams setup. So you could easily create a GPT with access to an internal wiki, code, project context, business processes, etc.
