I am a user who loves your product and would like to ask for your help with a couple of questions and feature suggestions
My API configuration

Base URL: https://api.example.com

Model ID: claude-opus-4-8

API Key: your-key

Questions:

Does SheetMagic support custom API base URLs and custom model IDs?

If yes, what is the =aitext() syntax to set provider, base_url, and model? (Is it something like =aitext("provider=openrouter; model=...; your prompt")?)

If no, are there any alternative Google Sheets AI tools you recommend that support custom API endpoints?

Even AI support tools told me I should stop using SheetMagic and switch to Google Apps Script or n8n instead

Does SheetMagic's =aiimage() function support custom API base URLs and custom image models?
If yes, how do I use =aiimage() with my custom API configuration?
