Image Models (Banana / Seedream / Midjourney)

Overview

Main image models currently configured in code:

• Banana Pro (nano-banana-pro)
• Nano Banana 2 (nano-banana-2)
• Seedream 5 Lite (doubao-seedream-5.0-lite)
• Z-Image (fast lightweight)
• Midjourney V7 (mj-v7)

Common capabilities

• text-to-image
• image-to-image
• multi-reference fusion (limits vary by model)

Practical differences

• Banana Pro: stable quality, up to 8 reference images.
• Nano Banana 2: broader ratio options, up to 14 references.
• Seedream 5 Lite: supports higher resolution tier (up to 3K).
• Z-Image: fast, low-cost draft generation.
• Midjourney V7: strong stylization controls and look diversity.

Common parameters (shown dynamically)

• aspectRatio / aspect_ratio
• resolution
• Midjourney-specific: speed, stylization, weirdness, variety, action

Reference limits (from current config)

• Banana Pro: up to 8
• Nano Banana 2: up to 14
• Seedream 5 Lite: up to 14
• Midjourney V7: up to 8 (required in some actions)

Tips

• Start with lower-cost models/settings, then upscale quality.
• Keep references stylistically coherent for more stable outputs.
• For production stories/ads, lock aspect ratio early.
