TRY TO AVOID
Not Ideal For
Ultra high resolution output
Practical limit is ~1024px, pushing beyond that introduces white halos and quality degradation.
Factual or knowledge grounded imagery
Cannot produce accurate infographics, diagrams, or historically precise outputs without explicit prompting.
Fast real time iteration
Multi step diffusion inference means noticeably slower generation, not suited for rapid live previews.
Natural language instruction editing
Cannot edit a specific element in an existing image by instructions.
Text & typography in images
Diffusion architecture produces unreliable text rendering.
