Stable Diffusion 3 Medium: A Smaller, But Much Better Model

One of the most significant aspects of Stable Diffusion 3 Medium is its reduced size compared to its larger counterpart, Stable Diffusion 3 Large. While SD3 Large boasts an impressive 8 billion parameters, SD3 Medium manages to pack a punch with just 2 billion parameters. This reduction in size has important implications for users, as it allows the model to run efficiently on consumer-grade hardware without compromising on quality.

The ability to generate high-quality images on standard consumer GPUs is a game-changer for many users. With a minimum requirement of only 5GB of GPU VRAM, SD3 Medium opens up the possibilities of advanced image generation to a wider audience. Whether you're an artist, designer, or simply a creative enthusiast, you can now harness the power of Stable Diffusion without the need for expensive, specialized hardware.

GPU Model VRAM SD3 Medium Performance
NVIDIA RTX 3060 12 GB 2.35 s/image (8 images)
NVIDIA RTX 3090 24 GB 3.15 s/image (8 images)
AMD Radeon RX 7900 XTX 24 GB 21 it/s

Stable Diffusion 3 Medium vs DALLE 3: More Photorealistic, Better Typography

One of the standout features of Stable Diffusion 3 Medium (Comparing to its competitors such as DALLE 3) is its ability to generate photorealistic images with unprecedented accuracy. The model has been fine-tuned to capture intricate details and textures, resulting in visuals that closely resemble real-world photographs. This level of photorealism is particularly impressive considering the reduced size of the model.

In addition to its photorealistic capabilities, SD3 Medium also excels in typography generation. The model has been trained to understand and render text with exceptional clarity and accuracy. Whether you're creating images with embedded text or generating standalone typography, SD3 Medium delivers results that are crisp, legible, and visually appealing.

Some examples of prompts that showcase SD3 Medium's photorealism and typography capabilities:

  • "A vintage 1950s diner with neon signs and classic cars parked outside"
  • "A futuristic cityscape with towering skyscrapers, flying cars, and holographic advertisements"
  • "An ancient Egyptian temple with hieroglyphics, towering statues, and a mysterious sarcophagus"

Stable Diffusion 3 Medium Prompts: Everything Gets Better and Easie

Another area where Stable Diffusion 3 Medium shines is in its ability to understand and interpret complex prompts.

  • The model has been designed to grasp the nuances of natural language, allowing users to provide detailed descriptions of desired scenes, objects, and compositions. SD3 Medium can parse these prompts and generate images that accurately reflect the user's intent.
  • Moreover, the model has a deep understanding of spatial relationships and compositional elements. It can effectively position objects within an image based on the provided prompt, taking into account factors such as size, placement, and interaction between elements.
  • This level of spatial awareness enables users to create visually coherent and well-composed images with ease.

Some examples that demonstrate SD3 Medium's complex prompt understanding and spatial relationships:

  • "A majestic dragon soaring over a misty mountain range at sunset"
  • "A cozy cabin in the woods surrounded by tall pine trees and a babbling brook"
  • "A magical forest filled with bioluminescent plants, glowing mushrooms, and enchanted creatures"

Resource Efficiency and Fine-Tuning Capabilities

Stable Diffusion 3 Medium's compact size not only makes it accessible to a wider range of users but also contributes to its resource efficiency. The model's reduced memory footprint allows it to run smoothly on standard consumer GPUs, minimizing the need for high-end hardware. This efficiency is particularly beneficial for users who want to generate multiple images in a short period or those working with limited computational resources.

Furthermore, SD3 Medium offers excellent fine-tuning capabilities. The model can absorb nuanced details from small datasets, enabling users to customize and adapt it to their specific needs. Whether you're working on a particular art style, a specific domain, or a unique set of visual elements, SD3 Medium's fine-tuning capabilities allow you to tailor the model to your requirements, resulting in more personalized and targeted image generation.

How to Use Stable Diffusion 3 API

Having trouble managing 10+ API subscriptions for AI Models?

No worries! Anakin AI is your All-in-one AI aggregator platform where you can easily access all LLM and Image Generation Models in One Place!

Get started with Anakin AI's API Integration Now!

Using the Stable Diffusion 3 API is a straightforward process. Here's a step-by-step guide on how to get started:

Step 1: Sign up for an API key

To access the Stable Diffusion 3 API, you need to sign up for an API key. Visit the Stability AI website and create an account. Once you have an account, navigate to the API Keys section and generate a new API key.

Step 2: Install the required libraries

To interact with the Stable Diffusion 3 API, you'll need to install a few libraries. You can install them using pip:

pip install requests pillow

Step 3: Make API requests

Now that you have your API key and the required libraries, you can start making API requests to generate images. Here's a sample code snippet in Python:

import requests
from PIL import Image
from io import BytesIO

api_key = "YOUR_API_KEY"
url = ""

prompt = "A beautiful sunset over a serene beach"

payload = {
    "text_prompts": [
            "text": prompt
    "cfg_scale": 7,
    "clip_guidance_preset": "FAST_BLUE",
    "height": 512,
    "width": 512,
    "samples": 1,
    "steps": 30,

headers = {
    "Content-Type": "application/json",
    "Accept": "application/json",
    "Authorization": f"Bearer {api_key}"

response =, json=payload, headers=headers)

if response.status_code == 200:
    data = response.json()
    for i, image_data in enumerate(data["artifacts"]):
        image_url = image_data["base64"]
        image ="generated_image_{i}.png")
    print(f"Request failed with status code {response.status_code}")

In this example, we define the API endpoint URL and the prompt for generating the image. We then set the desired parameters such as the image size, number of samples, and the number of steps for the diffusion process.

We create a payload containing the prompt and parameters, and set the headers with the API key and content type. Finally, we make a POST request to the API endpoint with the payload and headers.

If the request is successful (status code 200), we retrieve the generated image data from the response and save it as a PNG file. If the request fails, we print the status code for debugging purposes.

Step 4: Customize and experiment

Feel free to modify the code and experiment with different prompts and parameters to generate various types of images. You can adjust the cfg_scale to control the image's adherence to the prompt, change the clip_guidance_preset to influence the style, and modify the height and width to generate images of different sizes.

The Stable Diffusion 3 API offers a wide range of possibilities for generating creative and unique images. Explore the API documentation to learn more about the available parameters and options.

Remember to handle your API key securely and avoid sharing it publicly. With these steps, you're ready to start using the Stable Diffusion 3 API to generate stunning images from textual prompts!
