Introduction
Source4 is a Stable Diffusion 1.5/Dreambooth model trained on portraits with dramatic, multicolored lighting. These portraits are heavily inspired by modern, multicolored theatrical lighting (hence the name Source4). This model was fine tuned without prior preservation loss for 8000 steps on over 90 high quality 512x512 images.
In the prompt, use activation token source4 style
Recommendations
I recommend experimenting with different colors in your prompt. For example, adding teal tones or red tones to your prompt bring those respective colors out. Also try a smaller weight on the source4 style prompt (ie, (source4 style:0.8)), for a slightly less pronounced but more realistic effect.
Euler a and DPM++ 2S a Karras for 25-30 steps have typically given me the highest quality images. Euler a typically gives me more "dreamy" portraits while DPM++ 2S a Karras gives me more realistic portraits.
If the effect is too pronounced or faces are totally blurred out, I recommend decreasing the weight of the activation token. An alternative is to specify detailed face in the prompt to ensure a face is actually drawn.

What is source 4 v1.0?
source 4 v1.0 is a highly specialized Image generation AI Model of type Safetensors / Checkpoint AI Model created by AI community user civitai. Derived from the powerful Stable Diffusion (SD 1.5) model, source 4 v1.0 has undergone an extensive fine-tuning process, leveraging the power of a dataset consisting of images generated by other AI models or user-contributed data. This fine-tuning process ensures that source 4 v1.0 is capable of generating images that are highly relevant to the specific use-cases it was designed for, such as lighting, style.
With a rating of 0 and over 0 ratings, source 4 v1.0 is a popular choice among users for generating high-quality images from text prompts.
Can I download source 4 v1.0?
Yes! You can download the latest version of source 4 v1.0 from here.
How to use source 4 v1.0?
To use source 4 v1.0, download the model checkpoint file and set up an UI for running Stable Diffusion models (for example, AUTOMATIC1111). Then, provide the model with a detailed text prompt to generate an image. Experiment with different prompts and settings to achieve the desired results. If this sounds a bit complicated, check out our initial guide to Stable Diffusion – it might be of help. And if you really want to dive deep into AI image generation and understand how set up AUTOMATIC1111 to use Safetensors / Checkpoint AI Models like source 4 v1.0, check out our crash course in AI image generation.
