100K character restriction when retrieving data via API with an Action for a GPT

We are hitting the 100,000 character limit in the size of the API response with an underlying Action for our GPT. That’s obviously not the best user experience since the GPT doesn’t work without the data. We are hoping to see this limit raised soon.

I’ve not seen plans to raise it, as nice as it would be.
Do you need any help in trying to summarise the data or such?
