Top Stable Diffusion Cyberpunk Prompts

To test the following prompts I am using the SDXL model with a proper SDXL negative prompt:

blurry, out of frame, blurred, amateur, ugly, low quality, cropped, bad quality, sketch, low resolution, warped, crooked, deformed, cartoony, low detail.

You also can use the above negative prompt while working on cyberpunk prompts.

Now let’s see how my prompt generates images…

augmented reality fashion

Prompt: High-tech runway: models showcase augmented reality clothing. Holographic garments change patterns, blurring fashion and technology in this cyberpunk catwalk.

It is an example of an augmented reality fashion prompt. If you need more fashion prompts, read our article on stable diffusion clothing prompts.

Okay, we have seen some prompts to generate sci-fi images, now if you want to generate them on your end the most important thing is the model.

So, let’s discuss models for sci-fi images:

Best Stable Diffusion Sci-Fi Models

If you’re new to stable diffusion, you might not know how a model affects image generation. But if you’re experienced, you’re aware.

You also understand that finding the right model for a specific artistic style is challenging and time-consuming.

So, after lots of testing, we’ve put together a list of 5 sci-fi models for stable diffusion.

1. Sci-Fi Diffusion v1.0:

The model, titled “Sci-Fi Diffusion v1.0,” is a generalist Sci-Fi model based on SD v2.X.

It has been trained on 26,949 high-resolution and quality sci-fi-themed images for 2 epochs, equivalent to around 53,898 steps/iterations.

The training resolution was 640, but it performs well at higher resolutions.

Noteworthy features include its early version status, being in development, and its recommendation for samplers, such as Euler, Euler A, and DPM++ SDE Karras.

The base model is SD 1.5, and it is checkpoint-trained. The training trigger words include “SCI-FI,” “CASPIAN SCI-FI,” “STAR ATLAS,” “STAR CITIZEN,” and “RENDER.”

2. Sci-fi Environments:

The “Sci-fi Environments” model is designed to generate stunning sci-fi environments with a cinematic style.

Drawing inspiration from the realms of science fiction, this AI model excels at crafting immersive and visually captivating worlds.

Key features of the model include:

  1. Themes: Tailored for generating backgrounds related to cyber, sci-fi, cityscape, landscape, and general environments.
  2. Model Type: Labeled as “LORA.”
  3. Base Model: Built on SDXL 1.0.

3. Sci-Fi Angels:

The “Sci-Fi Angels” model is designed to create anime-style characters with a focus on angels.

Key details:

  • Strength Setting: The LORA has a strength setting of 0.6.
  • Trigger Words: The model responds to trigger words, including “SCIFI_ANGEL.”
  • Base Model: Built on SD 1.5.
  • Training Details: Trained for 10 epochs with 1,200 steps.

4. SciFi Ground Vehicles:

The “SciFi Ground Vehicles” model is designed to generate science fiction-themed ground vehicles, with a particular emphasis on cyberpunk and military aesthetics.

Usage Tips:

  • Recommended Weight: ~0.8
  • Trained on BriXL, which has a strong bias on SciFi, so users may need to adjust the weight if they desire more science fiction vibes.
  • Trigger words include “SCIENCE FICTION,” “VEHICLE,” “GROUND,” “HOVERING,” and “MILITARY.”

Training Details:

  • Base Model: SDXL 1.0
  • Trained for 40 epochs with 4,000 steps.
  • CLIP SKIP: 1

5. Sci-Fi Outfits – Wildcards:

The “Sci-Fi Outfits – Wildcards” model is a collection of sci-fi-themed outfit suggestions for use in sci-fi renders.

Requirements: To use this Wildcard collection, you need the Dynamic Prompts extension for Stable Diffusion.

The extension should be placed in the stable-diffusion-webui >> extensions >> sd-dynamic-prompts folder.

  • Base Model: SD 1.5
  • CLIP SKIP: 2

Final Verdict:

If you use these models according to your desired prompts, I hope you can create effective images.

So, use the prompts as you need, and do not forget to edit them as you desire because AI art becomes perfect through experiments.
