I'm attempting to test the image creation workflow in n8n based on the template that I imported from the video and I am receiving this error message, "Problem in node ‘Image Prompt‘ This request requires more credits, or fewer max_tokens. You requested up to 32768 tokens, but can only afford 5000. To increase, visit https://openrouter.ai/settings/credits and upgrade to a paid account". How can I fix this?

Anyone have thoughts on when it makes more sense to use n8n versus Zapier (or vice versa)? At first glance it seems that there n8n allows for more powerful solutions, especially when it comes to AI. Thoughts?
