Stable Diffusion 1.5 Model Overview and Technological Advancements
What is Stable Diffusion 1.5?
Stable Diffusion 1.5 is an open-source diffusion-based generative model developed by organizations such as Stability AI and LAION.Adopting the LDM architecture, it enables AI drawing with high efficiency and low barriers to entry.
| Version | Key features | Recommended video memory | Output size | Commercial Licensing |
|---|---|---|---|---|
| 1.4 | Open source, community ecosystem | 4GB | 512×512 | Commercial |
| 1.5 | Diverse styles, optimized synthesis quality | 4GB/6GB | 512×512 is better | Commercial |
| 2.1 | Enhanced text understanding | 6GB+ | 512×512 and above | Commercial |
| SDXL series | high resolution | 8-12GB | 1024×1024 | Commercial |
SD1.5 has become the mainstream for a long time due to its diverse styles and highly fine-tuned compatibility.
SD1.5 compared with similar AI models
Open source, self-deployment, unlimited customization, and rich community extensions.This makes SD1.5 superior to closed-source tools such as Midjourney and DALL·E 3.
| Model | price | Is it open source? | Can be deployed locally | Customization capabilities | Community Resources |
|---|---|---|---|---|---|
| Midjourney | subscription | 否 | 否 | 低 | Official/Limited |
| DALL·E 3 | Paid | 否 | 否 | Extremely low | official |
| SD1.5 | Free/Donation | 是 | 是 | Extremely high | Abundant (Civitai et al.) |
| SDXL | free | 是 | 是 | 高 | rapid growth |
SD1.5 is the core of the AI drawing ecosystem for secondary development and the LoRA and ControlNet standards.
Stable Diffusion 1.5 Hardware and Software Requirements
Recommended hardware configuration
| need | lowest | recommend |
|---|---|---|
| system | Win10/11/Linux | Windows 11 |
| graphics card | NVIDIA 4GB | NVIDIA 8GB+ |
| processor | Quad-core Intel/AMD | Six/Eight Cores |
| Memory | 8GB | 16GB+ |
| storage | 10GB | SSD 20GB+ |
A dedicated graphics card is highly recommended, with NVIDIA (supporting CUDA) being the best choice.
Software deployment recommendations
For beginners, it is recommended to use the "Akiba aaaki Integration Pack" orAUTOMATIC1111 WebUIOne-click package:
- Extract the files to your hard drive, double-click the main program, and access http://127.0.0.1:7860/ in your browser for web operation.
- If you don't have local hardware, you can easily deploy a large graphics card experience using mainstream cloud GPUs such as RainCloud.
Stable Diffusion 1.5 Core Functions and Parameter Details
Main interface and parameter logic
- Prompt/Negative Prompt: Describe the elements of expectation and avoidance.
- Sampling methods: Affects different styles and levels of detail (Euler, DPM++, etc.).
- StepsGenerally, 20-40 steps are recommended; more than that yields less benefit.
- resolution512x512 is the mainstream size; the larger the size, the more demanding it is on the graphics card.
- High-resolution repair (Hires. Fix)It helps to amplify and enhance details.
| parameter | Example | illustrate |
|---|---|---|
| Prompt | best quality, 8k, masterpiece, … | Key descriptions appear first and have high weight. |
| NegativePrompt | bad-hands-5, watermark, blurry | Filtering bad details |
| Steps | 20-30 | Balanced output quality |
| Sampler | Euler/DPM++ | Different styles require different choices |
| CFG Scale | 7 | Adjusting the influence of Prompt |
