A: Gemini I find is a bit tricky or confusing with Google But general easy to get an API key. The easiest way to access to Gemini and 200+ models is via OpenRouter. It adds about 5% to the cost, but its a fantastic way to try models. AahSheet is not designed to run the reasoning / thinking models yet. I will look into this next month or so. For now you will need to use models similar to 4o until I can complete larger update.
