Parameter Optimization: Getting the Best from Each

Both models respond differently to parameter adjustments. Knowing these differences changes everything.

Nano Banana Pro Parameter Strategy

• Keep prompts concise and technically descriptive
• Use negative prompts sparingly - the model already focuses on precision
• Stick to default sampling - custom sampling rarely improves quality
• Batch size matters more than individual image quality
• Resolution scaling is linear - double resolution = double time, predictable

Flux 2 Pro Creative Control

• Detailed, descriptive prompts work better than concise ones
• Negative prompts significantly impact artistic direction
• Experiment with sampling methods - each creates different artistic effects
• Quality over quantity - single images benefit from extra generation steps
• Non-linear scaling - higher resolutions unlock additional creative features

💡 Pro Tip: With Flux 2 Pro, adding "cinematic lighting, atmospheric, moody, textured" to prompts activates its artistic interpretation systems. With Nano Banana Pro, adding "technical, precise, geometric, accurate" enhances its strength areas.

Dynamic scenes demonstrate how each model handles motion—technical freeze versus cinematic blur.
