I regularly use a handful of GPTs in my writing processes and find their different tones and perspectives are really powerful with combined in a chain. Is there any way to use GPTs from the main UI as an API call so I can save myself so much copy and pasting?
Short answer is no, there is no API for GPTs.
But well.. most GPTs are merely a system prompt. The exception being some with a custom endpoint for extra services, which are slowing being replaced by MCPs.
So, depending on the complexity of what you need, it should be possible to implement an equivalent prompt using the API with a bit of creativity and effort.
