Maximum image resolution for the selected model is 4.19MP, b

Error message

Maximum image resolution for the selected model is 4.19MP, but {mp_provided:.2f}MP provided.

What it means

Raised by ByteDanceSeedreamNodeV2 in the is_pro branch when the resolved output size exceeds 4,194,304 pixels (4.19MP). Seedream 5.0 Pro caps output at 4.19MP (max_width=3136, max_height=2496 in its input schema), and the node enforces this locally before the API call.

Solutions

Choose a Pro preset from RECOMMENDED_PRESETS_SEEDREAM_5_PRO or set custom width/height so width*height <= 4194304 (e.g. 2560x1600).
Use 'seedream 5.0 lite' or 'seedream-4-5' when you need outputs above 4.19MP (they allow up to 16.78MP).
Downscale afterwards locally instead of asking Pro for an oversized render.

Example fix

// before
model: seedream 5.0 pro
size_preset: Custom
width: 3840, height: 2160 // 8.29MP -> raises

// after
model: seedream 5.0 pro
size_preset: Custom
width: 2560, height: 1600 // 4.10MP -> passes

Defensive patterns

Strategy: validation

Validate before calling

PRO_MAX = 4_194_304
assert width * height <= PRO_MAX, f'5.0 Pro max 4.19MP, got {width*height/1e6:.2f}MP'

Prevention

Clamp Pro requests to <= 4.19MP (e.g. 2560x1600).
Do not reuse 4K presets from Seedream 4.5 with 5.0 Pro.
Prefer the built-in Pro presets over custom sizes.

When it happens

Trigger: Model 'seedream 5.0 pro' with width*height > 4194304, e.g. a 4K preset like 3840x2160 (8.29MP) or custom 3136x2496 with a preset that multiplies over the cap.

Common situations: Reusing a 4K preset built for Seedream 4.5 (which allows up to 16.78MP) after switching the model to 5.0 Pro; assuming all Seedream tiers share the same maximum resolution.
