I have a few questions.

1. How can I prevent AI from automatically modifying content I've manually added?
2. Are there plans to incorporate newer AI models beyond GPT-4.0, such as GPT-4.1 or other advanced models?
3. When attempting to use the Custom Model feature for 9x16 aspect ratio generation, the system appears to get stuck in a processing loop. Is there a fix for this issue?
4. I'm experiencing difficulties when trying to edit a presentation with 9x16 dimensions and then save it as a template. What steps should I take to resolve this? The custom template does not work in 9x16
