GPT Custom Actions

Anyone else playing with custom GPTs? I’m wondering specifically about custom actions and anyone else’s thoughts on use cases.

If you aren’t familiar, custom actions let your Custom GPT connect to other systems by translating natural language prompts into correctly formatted API calls. This capability can empower anyone to connect systems without needing a developer, which could be a game-changer (I’ll likely write more about this later).

It took a little bit to figure out the OAuth credentials, but I’ve successfully connected my gmail and a sandbox GA4 property.



Now, I haven’t really scratched the surface yet, but I can see right away how enabling certain bulk actions might be useful this way.

Also, it could be really powerful if you are connecting multiple systems for analysis. GA4 + Salesforce could enable GPT to run regressions or more advanced ML models for marketing attribution for example. But I’m wary of this as you don’t see the actual API responses outside of the preview tool for debugging, and I’ve caught a lot of hallucinating in my tests. You probably would still want to have a Data Scientist supervising the results.

But in general it’s still going to be faster and easier to interact with the data in the respective systems designed for the purpose rather than having GPT execute GET calls for you. Even if you export as a csv and upload to GPT itself, it’s still probably faster and more reliable than a custom GPT assistant.

I’ll keep tinkering, but based on this I’m thinking the most value will be not in pulling data out of platforms to feed AI, but integrating AI into existing systems.
