Recap of SDXL Promises: Better Artworks, Intelligent Prompting, Advanced Controls, and Text Capabilities

Stability AI introduced SDXL last year with big promises for the AI art community. They claimed SDXL would deliver better and more challenging artworks, more intelligent and simpler prompting, easy fine-tuning and advanced controls, and enhanced text-to-image capabilities.

Specifically, they promised SDXL could handle more complex art styles and compositions. They also said users could describe desired scenes in normal human language using fewer words, without needing as many style keywords or negative prompts. Additionally, SDXL was supposed to make fine-tuning easier so users could train models on the fly. And although not directly claimed in promotions, the examples seemed to promise improved text-to-image performance.

These promises led many to eagerly anticipate SDXL. But now that it has been out for a while, it is fair to ask whether SDXL truly delivered what was hoped for.

Better Artworks and Challenging Concepts

Stability AI said SDXL would produce better quality artworks capable of more complex concepts and styles. In practice though, many feel SDXL is not that much better than community-trained SD 1.5 models in this regard. Those 1.5 models can already handle intricate compositions thanks to tools like ControlNet and img2img. Meanwhile, models like MidJourney seem more effectively able to render authentic artistic styles with appropriate color choices, harmony, and composition. SDXL results often still feel somewhat stiff and unnatural in comparison.

More Intelligent and Simpler Prompting

Stability AI also promised SDXL would be more intelligent, requiring only simple natural language prompting without needing as many descriptive keywords. However, based on user experiences so far, this does not seem to be the case. Prompt engineering with descriptive keywords and negative prompts is still critical for SDXL to produce a desired result. In contrast, other models like DALL-E 3 can interpret freeform natural language more effectively to generate images matching what users truly imagine.

Fine-Tuning and Advanced Controls

Additionally, SDXL was supposed to enable easy fine-tuning and advanced controls for customizing models. But many users report community-trained SD 1.5 models still provide more flexible control and customization. The base SDXL model seems too rigid and limited for extensive fine-tuning compared to SD 1.5. More work likely needs to be done by the community to unlock SDXL's full potential here.

Enhanced Text to Image Capabilities

Lastly, while not directly claimed, SDXL promo images hinted at enhanced text-to-image generation ability. But so far, users have not reported dramatically improved text-to-image results compared to SD 1.5 models. Once again, other models appear to outperform SDXL in intelligently rendering images from textual descriptions at this point in time.

Community Feedback on SDXL

Given the high expectations set for SDXL, many users ended up disappointed with the results so far. As artist Chust Meyer summed up, 'SDXL wasn't as much of a leap as I was hoping to see in a year for that space.' Others echo this sentiment that SDXL feels more like a slightly improved SD 1.5 rather than a dramatic generational step forward.

For creative and artistic use cases, factors like authentic style rendering, flexible control, and accessible hardware requirements are just as important as purely visual quality. By those measures, SDXL falls short of community hopes currently.

But it is still early and SDXL may improve with further community exploration. As one user points out though, 'the community-trained SD 1.5 models are not as good as the community-trained SDXL models' so far, likely because SD 1.5 offers a more flexible base for customization and fine-tuning.

In the end, the community consensus seems to be that SDXL is disappointing given what was hoped for and expected. For most real-world applications so far, SD 1.5 models fine-tuned by the community appear to actually outperform SDXL in important ways.

Comparing SDXL and SD 1.5 Image Quality

Visually inspecting sample SDXL and SD 1.5 images side-by-side reveals relatively minor quality differences currently. SDXL results tend to show slightly more precise details and textures. However, the overall image quality and aesthetic appeal is not dramatically improved.

This aligns with community sentiment that SDXL samples seem more like incrementally improved SD 1.5 results rather than representing a major leap forwards. The changes are subtle enough that most users would likely struggle to reliably distinguish SDXL vs SD 1.5 outputs without checking model version metadata.

SDXL Model Download Statistics

Download statistics provide another objective measure for gauging SDXL adoption and usage so far. On Hugging Face's model hub, the base SD 1.5 model has over 670,000 downloads. In comparison, the base SDXL model sits at just under 1 million downloads.

Accounting for SDXL's shorter public availability, its download figures are still relatively low, suggesting limited community adoption. Fine-tuned SDXL models have even fewer downloads, most likely due to hardware constraints limiting accessibility and experimentation.

Meeting Community Needs for AI Art

For the AI art community, factors like authentic style rendering, customization flexibility, and accessibility are more important than pure visual accuracy. This aligns with how human artists think - creative expression matters more than photographic realism.

Unfortunately SDXL falls short in serving these community needs currently. But the strengths of SD 1.5 demonstrate there is still plenty of room for improvement as AI art continues advancing rapidly.

Conclusion and Path Forward

In the end, while SDXL appeared highly promising on paper, real-world performance has left much to be desired so far based on community feedback. SDXL has not yet lived up to its full potential compared to stable diffusion 1.5 and other models.

But the AI art field continues progressing quickly thanks to open collaboration between companies like Stability AI and the wider community. There remains much room for growth through further tweaking of SDXL and development of new techniques.

The community is eager to work together with Stability AI to build models matching everyone's needs and expectations moving forward!


Q: What promises were made about SDXL capabilities?
A: Stability AI promised SDXL would have better artworks, more intelligent prompting, easy fine-tuning, and enhanced text-to-image compared to SD 1.5.

Q: What hardware is needed to run SDXL models?
A: SDXL requires high-end GPUs with lots of VRAM, which many users cannot access, limiting adoption.

Q: How does SDXL image quality compare to SD 1.5?
A: In many cases, SD 1.5 with upscaling matches or exceeds SDXL image quality while being easier to use.

Q: Why are SD 1.5 community models more popular than SDXL?
A: Community models for SD 1.5 enable more artistic flexibility and run on more accessible hardware.

Q: Does SDXL meet artist needs for experimentation?
