Stable Diffusion Prompt Limit

Crafting effective AI prompts is key to unlocking the potential of modern generative AI models like DALL-E, Stable Diffusion, and others. A good prompt acts like a set of instructions, guiding the model to create what you envision. Mastering prompt engineering takes experimentation, an understanding of how models work, and plenty of trial and error.

In this article, I’ll share my top prompt examples and techniques to help you get started. Whether you want to generate art, continue text stories, fix image issues, or more, these prompts demonstrate what’s possible.

What Makes a Good Prompt?

Before jumping into examples, let’s cover what makes an effective AI prompt:

  • Clear instructions – Be as specific as possible about what you want to generate, while keeping prompts reasonably short. Use descriptive words and concrete details.
  • Format correctly – Follow the prompt format guidelines for whatever model you use. For example, Stable Diffusion has a 75 token limit.
  • Check for unintended bias – Word choices can perpetuate harmful stereotypes. Review prompts carefully.
  • Leave room for creativity – Constraints like style and composition guidance are good, but don’t over-define the output.

Awesome Prompt Examples

Now, let’s look at some awesome prompt examples you can try yourself!

Art Prompts

AI art represents one of the most popular uses of generative models today. These prompts show what’s possible:

A colorful ink painting of a girl playing near a riverbank in the style of traditional Chinese brushwork.

A regal elf queen wearing a gown made of autumn leaves, oil painting by Alphonse Mucha

An abstract silhouette of a city skyline with vibrant neon colors in the style of cyberpunk concept art

Continue the Story

AI models can continue text stories, poems, lyrics, and more. The key is providing enough context and a strong starting point.

A short fantasy story about a wizard who discovers an ancient talking stone:

The old wizard walked through the dark forest, lantern in hand. In the thicket, a glow caught his eye. It was a stone that glimmered from within. As he picked it up, a gravelly voice said "I am the Oracle Stone, granter of knowledge." The wizard asked "What fate befalls the kingdom?"

Continue the lyrics of a song about pursuing your dreams and overcoming self-doubt:

Verse 1: 
The critics all jeer as I take the stage
My hands shake, I feel half my age
The spotlight, it waits for my voice 
But I'm nervous, I don't have a choice
This is my time even if I fail
Success rides along the wings of the gale

Image Editing

Fix issues in existing images through inpainting, outpainting, and more:

Remove the street sign from this city photo using inpainting:

Add a futuristic skyline background behind this portrait to make it look like a sci-fi movie poster

And So Much More

Possibilities with generative models expand daily. Here are some other fun prompt ideas:

  • Generate a recipe card for baked ziti with an Italian flair and illustration
  • Create a logo for a startup called Blue Sky Software with clouds and minimalist plane imagery
  • Continue the code for a basic Python machine learning script that processes iris data

The only real limits are your imagination and effort put into fine-tuning prompts.

Prompt Engineering Tips

Through my experimentation with AI models, I’ve picked up some useful prompt engineering tips:

Check Token Usage

Especially with Stable Diffusion, pay attention to token usage. Go over the limit and the system ignores excess prompt content. Check the documentation for the max tokens allowed.

Try Prompt Weighting

Prioritize the most important parts of your prompt by weighting terms. For example, in Stable Diffusion you can use [flower:0.8] to boost influence of “flower” on the output.

Use Negative Prompts

Add negative prompts to specify what NOT to include. This helps narrow down results. For example, use -“copyrighted characters” or -“text” to avoid outputs you don’t want.
