A: Good question. The AI is from the API key you add. BOYK is focused on OpenRouter, Straico, or OpenAI, or Claude directly. I do most of my building and testing with 4o-mini and 4o from OpenAI. The flows only work with the 4o task models. We are not able to use the thinking models. The AI credits used will be from your API key you add. To use NeuronWriter credits then you have to manually run this inside NeuronWriter. There is no way for me to use the Neuron Ai credits directly in the Google Sheet. Hope this all makes sense. Let me know if any more questions and happy to answer.

Hope this is helpful.
