Core Parameters
| Parameter | Type | Description | Modes |
|---|---|---|---|
prompt
|
string | Required. Text prompt for image generation |
T2I

negative_prompt
|
string | Negative prompt to guide generation away from undesired content |
T2I

T2I

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
|
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
|
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.
|
T2I
|
size
Exact pixel dimensions
"1920x1080"
aspect_ratio
Shape only, default scale
"16:9"
resolution
Scale tier, preserves shape
"1K"
Priority when combined
size
›
aspect_ratio + resolution
›
aspect_ratio
›
resolution
size is most specific and always wins. aspect_ratio and resolution control shape and scale independently.
How matching works
Shape matching
– we pick the closest supported ratio.
Ask for
7:1 on a model with
4:1 and 8:1,
you get 8:1.
Scale matching
– providers use different tier formats:
K tiers (
0.5K 1K 2K 4K)
or megapixel tiers (0.25 1).
If the exact tier isn't available, you get the nearest one.
Dimension clamping
– if a model has pixel limits, we clamp dimensions to fit and keep the aspect ratio intact.

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.

HiDream I1 Fast starts at $0.005 per image through Lumenfall. Pricing varies by provider. Lumenfall does not add any markup to provider pricing.
How do I use HiDream I1 Fast via API?
You can use HiDream I1 Fast through Lumenfall's OpenAI-compatible API. Send requests to the unified endpoint with model ID "hidream-i1-fast". Code examples are available in Python, JavaScript, and cURL.
Which providers offer HiDream I1 Fast?
HiDream I1 Fast is available through fal.ai and Replicate on Lumenfall. Lumenfall automatically routes requests to the best available provider.
Overview
HiDream I1 Fast is a distilled text-to-image model developed by HiDream AI, optimized for low-latency image generation. It is a high-speed variant of the company’s flagship 17-billion parameter model, designed to retain the compositional intelligence of a large-scale architecture while significantly reducing inference costs and generation time.
Strengths
- Low Latency Generation: The distillation process allows the model to produce high-resolution images in a fraction of the time required by standard diffusion models.
- Multi-Subject Composition: Leveraging its 17B-parameter lineage, the model excels at managing spatial relationships and interactions between multiple distinct objects within a single frame.
- Prompt Adherence: It demonstrates high fidelity to descriptive text inputs, particularly when handling complex attributes such as lighting conditions, material textures, and specific artistic styles.
- Resource Efficiency: Provides a high quality-to-cost ratio, making it suitable for applications that require massive batches of image generation at a starting price of $0.005 per output.
Limitations
- Detail Nuance: As a distilled model, it may lack some of the fine-grained textural detail and edge sharpness found in the full 17B parameter non-distilled version.
- Text Rendering: Like many diffusion-based architectures, it may struggle with generating lengthy or highly specific typographic strings within the image.
- Photorealism Extremes: While it handles stylized and general photographic content well, it may produce occasional artifacts in anatomy or complex environmental reflections compared to slower, specialized photorealistic models.
Technical Background
HiDream I1 Fast is based on a transformer-heavy diffusion architecture, utilizing a massive 17-billion parameter backbone. The model employs knowledge distillation techniques to compress the computational requirements of the teacher model into a faster student model, prioritizing inference speed without sacrificing the fundamental semantic understanding acquired during large-scale pre-training.
Best For
HiDream I1 Fast is an ideal choice for real-time creative tools, social media asset generation, and rapid prototyping where speed is as critical as aesthetic quality. It is also well-suited for high-volume workflows like generating game assets or marketing variations. You can access HiDream I1 Fast through Lumenfall’s unified API and interactive playground, allowing for easy integration into existing production pipelines.
