Core Parameters
| Parameter | Type | Description | Modes |
|---|---|---|---|
prompt
|
string | Required. Text prompt for image generation |
T2I
Edit
|
Size & Layout
| Parameter | Type | Description | Modes |
|---|---|---|---|
size
|
string |
Image dimensions as WxH pixels (e.g. "1024x1024") or aspect ratio (e.g. "16:9")
WxH determines both shape and scale (aspect_ratio and resolution are ignored when size is provided). W:H format is equivalent to aspect_ratio.
|
T2I
Edit
|
aspect_ratio
|
string |
Aspect ratio of the output image (e.g. "16:9", "1:1")
Controls shape independently of scale. Use with resolution to control both. If size is also provided, size takes precedence. Any ratio is accepted and mapped to the nearest supported value.
|
T2I
Edit
|
resolution
|
string |
Output resolution tier (e.g. "1K", "4K")
Controls scale independently of shape. Higher tiers produce larger images and cost more. If size is also provided, size takes precedence for scale. Any tier is accepted and mapped to the nearest supported value.

Parameter Normalization
How we handle parameters across different providers
Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:
| Behavior | What happens | Example |
|---|---|---|
passthrough |
Sent as-is to the provider | style, quality |
renamed |
Same value, mapped to the field name the provider expects | prompt |
converted |
Transformed to the provider's native format | size |
emulated |
Works even if the provider has no concept of it | n, response_format |
Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Overview
Wan 2.7 Pro is a high-resolution diffusion model developed by Alibaba designed for advanced image synthesis and sophisticated image-to-image editing. It represents a significant iteration in the Wan model family, distinguished by its native support for 4K resolution output and enhanced spatial coherence. The model allows users to generate visual content from natural language descriptions or modify existing images through precise editing workflows.
Strengths
- High-Resolution Fidelity: Supports native 4K image generation, maintaining sharp textures and fine details that often blur or artifact in lower-resolution models.
- Multi-Image Contextual Awareness: Excels at tasks requiring the synthesis of information across multiple input images, making it effective for consistent character rendering or style transfer.
- Precise Image Editing: The model provides high control during image-to-image tasks, allowing for structural modifications while preserving the overall composition and lighting of the source material.
- Complex Prompt Adherence: Demonstrates improved understanding of lengthy, descriptive prompts, accurately mapping nested attributes and spatial relationships to the final output.
Limitations
- Hardware and Latency Requirements: Due to the complexity of 4K synthesis and the model’s architecture, generation times are typically longer compared to “Turbo” or distilled small-scale models.
- Specific Aesthetic Bias: Like many models in the Wan family, it may lean toward a specific digital art style or photorealistic polish that might require prompt engineering to override for more stylized or abstract requests.
Technical Background
Wan 2.7 Pro is built on an evolution of the DiT (Diffusion Transformer) architecture, optimized for handling massive spatial dimensions without losing global consistency. The training process involved a multi-stage approach, utilizing a curated dataset of high-resolution imagery and detailed captioning to improve the alignment between text tokens and visual patches. This version introduces refined attention mechanisms to manage the computational overhead of 4K processing while maintaining high signal-to-noise ratios.
Best For
This model is best suited for professional workflows where output resolution and detail are non-negotiable, such as digital marketing assets, background plates for VFX, and high-end conceptual art. Its image-editing capabilities make it a strong choice for iterative design cycles where an artist needs to transform a sketch or a low-fidelity reference into a production-ready asset. Wan 2.7 Pro is available for testing and integration through Lumenfall’s unified API and interactive playground.
