Features

Nucleus Image Text-to-Image

Nucleus Image Text-to-Image generates high-quality images from text prompts with precise control over inference steps, guidance scale, and aspect ratio. An affordable, flexible text-to-image model built for creative and production workflows.

Why Choose This?

• Fine-grained generation control Adjust inference steps (1–100) and guidance scale (0–20) to tune the balance between creativity and prompt adherence.

• Negative prompt support Specify what to exclude from the output for more precise control over the result.

• Multiple aspect ratio presets Choose from 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, or 2:3 to match any platform or format.

• Batch generation Generate up to 2 images per run for quick side-by-side comparison.

• Reproducible results Use the seed parameter to lock in a specific output for consistent iteration.

• Output format choice Export in PNG or JPEG based on your delivery requirements.

Parameters

How to Use

1. Write your prompt — describe the subject, scene, style, lighting, and mood.
2. Add negative prompt (optional) — specify elements you want to exclude.
3. Select aspect ratio — choose the format that fits your target platform.
4. Set num_images (optional) — generate 1 or 2 images per run.
5. Adjust inference steps and guidance scale (optional) — higher steps for more detail, higher guidance for stricter prompt adherence.
6. Choose output format — png for lossless, jpeg for smaller file size.
7. Set seed (optional) — fix the seed to reproduce a specific result.
8. Submit — generate and download your image.

Pricing

Just $0.01 per image.

Best Use Cases

• Rapid prototyping — Generate visual concepts quickly at very low cost for iteration and ideation.
• Social media content — Create platform-optimized images across multiple aspect ratios.
• High-volume workflows — Affordable per-image pricing makes it ideal for large-scale generation pipelines.
• Creative exploration — Tune inference steps and guidance scale to explore different visual styles from the same prompt.
• Developer integrations — Embed flexible, low-cost image generation into any app or workflow.

Pro Tips

• Higher num_inference_steps (50–100) produces more detailed and refined results; lower values (10–20) are faster for quick drafts.
• Increase guidance_scale for stricter prompt adherence; lower values allow more creative variation.
• Use negative_prompt to avoid common artifacts like blurry faces, extra limbs, or unwanted styles.
• Generate 2 images per run to quickly compare variations before committing to a final render.
• Fix the seed while adjusting other parameters to isolate the effect of each change.

Notes

• Only prompt is required; all other parameters are optional.
• Maximum 2 images per generation run.
• Please ensure your content complies with WaveSpeed AI’s usage policies.
