Hi there,
I used Paulus Schoutsens initial blueprint and extended it with an output and the possibility to have a complete custom promt to ask to the AI.
For me it worked fine with the Google Generative AI Integration (not yet with the open router integration): Google Generative AI - Home Assistant
This blueprint will gonna be extended more and more - so input is welcome 
blueprint:
name: AI camera analysis
description: >-
📷 ⚙️ v0.15 <br>

This is an extended version, of Paulus Schoutsens intitial blueprint to analyze camera footage with AI.
