Positive prompt

A professional studio portrait of a creative director wearing a black turtleneck, soft key light, subtle background gradient, photorealistic, highly detailed, sharp focus, clean composition, 85mm lens, shallow depth of field, soft key light with subtle rim light, Keep the subject clear, preserve realistic proportions, and avoid cluttered backgrounds.

Negative prompt

low quality, low resolution, blurry, out of focus, bad anatomy, bad hands, extra fingers, missing fingers, distorted face, deformed body, duplicate limbs, long neck, cross-eye, poorly drawn eyes, text artifacts, watermark, logo artifacts, jpeg artifacts, noisy background, oversaturated, plastic skin, over-sharpened, messy composition

Recommended settings

Model: SDXL Size: 1024x1024 (1:1) Sampler: DPM++ 2M Karras Steps: 35 CFG scale: 7 Seed: random or lock after a good first result Hires fix: optional for final upscales

How to make Stable Diffusion prompts more controllable

Stable Diffusion workflows are easier to tune when the positive prompt, negative prompt, model, sampler, steps, CFG scale, and image size are kept separate. This generator gives you a clean starting point for each piece.

Separate positive and negative

Use the positive prompt for what you want, and reserve the negative prompt for artifacts and failure modes.

Match model and style

Choose realistic wording for photoreal models, anime wording for anime models, and broader scene language for SDXL.

Start with stable settings

Sampler, steps, CFG, and size matter. Start simple, then lock the seed after a promising result.

Best practices for Stable Diffusion prompts

Keep positive prompts descriptive but organized. Start with the subject, then add style, lighting, camera, quality, and details. Avoid mixing too many unrelated aesthetics in one prompt.

Negative prompts should target common failure modes. Bad anatomy, extra fingers, blurry details, watermarks, text artifacts, and noisy backgrounds are useful defaults for many Stable Diffusion workflows.

What is a Stable Diffusion prompt generator?

A Stable Diffusion prompt generator creates a positive prompt, negative prompt, and recommended settings for image generation workflows such as SDXL, Stable Diffusion 1.5, realistic models, and anime models.

How do I write better Stable Diffusion prompts?

Describe the subject first, then add style, quality terms, camera or composition, lighting, and any extra constraints. Keep the negative prompt focused on common artifacts you want to avoid.

What should go in a negative prompt?

Use negative prompts to reduce blurry images, bad anatomy, extra fingers, distorted faces, duplicate limbs, watermarks, text artifacts, noisy backgrounds, and messy composition.

What settings should I start with?

A practical starting point is SDXL, DPM++ 2M Karras, 25-35 steps, CFG around 7, and a size that matches the intended aspect ratio.
