Image Generation Guide

Choosing the Right Model

Use Case	Recommended Model
Photorealistic photos	`flux-1.1-pro` or `gpt-image-1.5`
Product shots	`flux-1.1-pro`
Artistic / illustration	`midjourney-v6` or `midjourney-turbo`
Quick generation	`dall-e-3` (5–13 tkn)
High-res 2K output	`nano-banana-pro`
Image editing / inpainting	`flux-kontext-pro`

Prompt Writing Tips

Be specific: Instead of "a car", write "a red 1967 Ford Mustang on Route 66 at sunset, wide angle, film grain" Use style references: cinematic, studio photography, oil painting, 8k, photorealistic, bokeh Negative prompts (Flux, SD): Use them to remove common artifacts: "blurry, low quality, distorted hands, watermark, text"

Error Handling

If image generation fails, the system will display an error message for 6 seconds. Common error types include:

Model overloaded: The model is temporarily under high demand. Wait a few minutes or try a different model.
Generation timeout: The request took too long to complete. Try again with a simpler prompt.
Content policy violation: Your prompt was blocked by moderation filters. Modify your description.
Insufficient tokens: Top up your account balance.
Network issues: Check your internet connection.

Aspect Ratio Guide

Use Case	Size
Social square	`1024x1024`
Portrait / mobile	`768x1344` or `9:16`
Landscape / banner	`1344x768` or `16:9`
Story	`1024x1536`

Reproducible Results

Use the seed parameter to get the same image with the same prompt:

result = requests.post(
    "https://elumenta.ru/api/v2/generate",
    headers={"Authorization": "Bearer nb_YOUR_API_KEY"},
    json={
        "model": "flux-1.1-pro",
        "prompt": "Blue gradient abstract background",
        "seed": 12345
    }
)
# Same seed + same prompt = very similar output
