Which Image Gen model is best for infographics?

Hello guys,

I have a summary workflow for my school where I have Gemini summarize the lecture content, then generate infographics on said content. However, gemini's style keeps constantly changing, running out of limits and other stupid bs like that. Its unreliable. What image gen model is best for the task of complex infographic generation? Also, what model could take the input and actually produce it into a infographics suitable prompt? I usually have Qwen 27B (lately qwen flash next) generating text content for me but If I run the image model next to it im afraid ill run out of vram pretty fast.
