You can add "Use AI" columns to waterfalls - they're listed as one of the advanced actions you can perform when creating waterfall sequences. [1] Waterfalls allow you to reorder, add, or delete data providers in your sequence. [2]
The "Failed to update waterfall" error could be related to several factors, but the sources don't specify the exact cause for this particular error message.
Can you click into the specific cell where you're seeing this error to get more details about what's causing the failure?

That setup should work fine - you can definitely chain Use AI columns in waterfalls. [1] Waterfalls are now editable, so you can add, remove, or reorder providers including AI models. [2]
For your specific setup with Gemini first, then 4o-mini:
1.
In your waterfall sequence, make sure Gemini is positioned first
2.
Add 4o-mini as the second step in the sequence
3.
You can reorder these if needed using the waterfall configuration [3]
Since you're getting "Failed to update waterfall," can you click into the specific cell showing this error? That'll give us more details about what's causing the failure.

Chaining two AI steps in a waterfall is generally possible (you can reorder, add, or delete providers in the waterfall sequence). [1] If you’re seeing “Failed to update waterfall”, it may be caused by table/column constraints or a configuration issue. [2]
