We're excited to announce that Iconwiz now supports two of the most anticipated AI image models of 2026: ByteDance's SeedDream 5.0 and Google's NanoBanana 2. These flagship models represent significant leaps forward in AI image generation, and we're among the first platforms to make them available for icon design workflows.

SeedDream 5.0: ByteDance's 3K Generation Powerhouse

SeedDream 5.0 is ByteDance's latest flagship model, and it's a substantial upgrade from the already impressive SeedDream 4 series.

What makes it special:

Native 3K resolution generation — Generate images at up to 3072×3072 pixels directly, without upscaling artifacts. For icons that need to look crisp at every size, this native high-resolution output is invaluable.
Enhanced reference image support — Upload up to 14 reference images to guide the generation. Want your icon to match your brand's existing visual language? Feed it examples and watch it understand your aesthetic.
Improved prompt adherence — SeedDream 5.0 follows complex prompts with remarkable accuracy. Describe a "minimalist gradient icon with a stylized mountain peak and subtle aurora effects" and it delivers exactly that.
Better text rendering — While we generally recommend avoiding text in icons (it doesn't scale well), when you need it, SeedDream 5.0 handles typography better than any previous version.

For icon generation specifically, the native 3K output means you're starting with more detail than you'll ever need. Downscaling from 3K to your target sizes preserves sharpness in ways that upscaling from 1K never could.

NanoBanana 2: Google's Conversational Image Editor

NanoBanana 2 takes a different approach. Built on Google's latest Gemini architecture, it excels at iterative refinement and multi-image fusion.

Key capabilities:

Conversational editing — Describe changes in natural language. "Make the background warmer," "add a subtle glow around the main element," "shift the composition slightly left." NanoBanana 2 understands context and applies changes intelligently.
Multi-image fusion — Combine elements from up to 12 reference images into a cohesive output. Extract the color palette from one image, the composition from another, and the style from a third.
Character consistency — When generating multiple variations, NanoBanana 2 maintains consistent style and character across outputs. Essential when you're exploring different directions but want to stay within a coherent visual family.
Fast iteration — At 1.0x cost multiplier, NanoBanana 2 is priced for exploration. Generate dozens of variations without burning through your credits.

The conversational editing capability is particularly powerful for icon refinement. Instead of regenerating from scratch when something's almost right, you can nudge the output toward your vision with natural language instructions.

Why These Models Matter for Icon Design

Icons occupy a unique space in design. They need to:

Communicate instantly — Users glance at icons for milliseconds
Scale gracefully — From 16×16 favicons to 1024×1024 App Store assets
Stand out while fitting in — Distinctive but not jarring
Work across contexts — Light mode, dark mode, various backgrounds

SeedDream 5.0's high-resolution output addresses the scaling challenge directly. Start with more pixels than you need, and every downscaled version retains clarity.

NanoBanana 2's iterative refinement addresses the creative challenge. Icon design is rarely a one-shot process — it's about exploring variations and converging on the right solution. Conversational editing makes that exploration faster and more intuitive.

How to Use Them in Iconwiz

Both models are available now in the icon editor:

For generation: Select SeedDream 5.0 or NanoBanana 2 from the model dropdown
For editing: Use NanoBanana 2's conversational mode to refine existing images
For reference-guided generation: Upload your brand assets and let the models learn your style

We recommend starting with SeedDream 5.0 for initial concept generation — its 3K output gives you maximum flexibility. Then use NanoBanana 2 for refinement passes, leveraging its conversational editing to dial in the details.

Pricing

Both models are available at competitive rates:

SeedDream 5.0: 1.0x cost multiplier (1 credit per image)
NanoBanana 2: 1.0x cost multiplier (1 credit per image)

No premium pricing for flagship models. We believe the best tools should be accessible.

What's Next

The AI image generation space continues to evolve rapidly. We're committed to integrating the best models as they become available, giving you access to cutting-edge capabilities without the complexity of managing multiple APIs and accounts.

SeedDream 5.0 and NanoBanana 2 represent the current state of the art. But we're already watching what's coming next — and we'll be ready when it arrives.
