Which Should You Choose? Stable Diffusion 1.5 or SDXL?
TLDRThe video script discusses the differences between Stable Diffusion 1.5 and its XL variant. It highlights the native resolutions, with 1.5 being 512x512 and XL offering a higher 1024x1024. The XL model supports higher resolutions and is less prone to deformities at larger sizes. The script also compares the effectiveness of negative prompts and the use of filters, showing that Stable Diffusion XL produces better images at larger dimensions without extensive prompting. Additionally, the refiner model in XL enhances details, providing an advantage for detailed images, though it should be used cautiously to avoid messiness.
Takeaways
- 🌟 Stable Diffusion 1.5 and SDXL are two versions available on the playground platform, with 1.5 being the older model.
- 📸 SDXL has a higher native resolution of 1024x1024 compared to 1.5's 512x512, allowing for more detailed images.
- 🚀 When using 1.5 beyond optimal sizes, there's a higher chance of image deformities, such as double heads or deformed limbs.
- 🎨 SDXL can handle larger image sizes, like 1536x640, with less likelihood of such deformities.
- 🔍 In the demonstration, using 1.5 with a simple prompt and 512x512 resolution yielded somewhat similar but not great results.
- 👌 Increasing the resolution to 1024x768 with 1.5 resulted in more distorted images, highlighting the limitations of the model at larger sizes.
- 💡 Using negative prompts with 1.5 can lead to more coherent and acceptable images, showing the model's dependency on precise instructions.
- 🌈 The use of filters with 1.5 can significantly improve image coherency and aesthetics, even at larger dimensions.
- ✨ SDXL offers a refiner model that enhances details, making it advantageous for images requiring intricate details.
- 📝 Filters are easily identifiable in the platform by their labels, with different sets available for SDXL and 1.5.
- 📈 For beginners, it's recommended to start with SDXL due to its easier prompting, but achieving great results with 1.5 can be very rewarding.
Q & A

🖼️ Comparison of Stable Diffusion 1.5 and SDL 1.5
This paragraph introduces the differences between the two versions of the Stable Diffusion model, specifically focusing on their native resolutions. It explains that Stable Diffusion 1.5 has a 512x512 resolution, while the newer SDL 1.5 model offers a higher 1024x1024 resolution. The speaker highlights that higher resolutions in SDL 1.5 lead to better image quality and less likelihood of deformities such as double heads or other anomalies. The paragraph also discusses the practical application of these models by showing examples of images generated using both versions. The speaker notes that while 1.5 may require more negative prompts and filters to achieve better results, SDL 1.5 can produce higher quality images at larger sizes without the need for additional prompts or filters.
🔍 The Role of the Refiner Model in SDL 1.5
This paragraph delves into the additional feature of the SDL 1.5 model, the refiner. It explains that the refiner is not mandatory but can significantly enhance the details in the generated images. The speaker demonstrates this by adjusting the refinement slider and comparing the original and refined images, showing a marked improvement in the intricacy and definition of details. The paragraph also touches on the importance of using the refiner judiciously to avoid over-complicating the images. Furthermore, the speaker clarifies how to identify the appropriate filters for each model and suggests starting with SDL 1.5 for easier prompting, while acknowledging that achieving great results with the older 1.5 model can yield amazing images.
