Supported Text-to-Image Models

Ideon currently supports these model IDs:

• black-forest-labs/flux-schnell (default)
• black-forest-labs/flux-2-pro
• bytedance/seedream-4
• google/nano-banana-pro
• prunaai/z-image-turbo

Override Handling

User-provided t2i.inputOverrides are sanitized before runtime:

• Non-user-configurable fields are dropped
• Values are coerced and validated by type
• Invalid values are ignored

Pipeline-Managed Fields

Depending on model capabilities, Ideon may set pipeline fields automatically:

• aspect_ratio
• width
• height

This preserves stable image sizing and layout intent.

Selection Tips

• Start with default flux-schnell for speed
• Increase quality-focused fields only after baseline stability
• Use dry-run to validate orchestration before live image spend

Practical Tradeoffs

Model	Speed	Typical Quality	Best Use
black-forest-labs/flux-schnell	Fast	Good baseline	Iteration, high-throughput drafts
black-forest-labs/flux-2-pro	Medium	Higher fidelity	Hero visuals, polished cover images
bytedance/seedream-4	Medium	Strong composition	Balanced speed/quality workflows
google/nano-banana-pro	Medium	Style-consistent outputs	Brand-like variation and consistency
prunaai/z-image-turbo	Fast	Lightweight	Quick exploratory rendering

Common Override Patterns

Use t2i.inputOverrides when you need model-specific tuning:

• Output format tuning (for example png vs webp)
• Model-native quality knobs where supported
• Count/variant controls where allowed

Example:

{
	"settings": {
		"t2i": {
			"modelId": "black-forest-labs/flux-schnell",
			"inputOverrides": {
				"output_format": "png"
			}
		}
	}
}

If an override is invalid for the selected model, Ideon drops it during validation.
