Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
DeepSeek
- API pricing details not published on main site; requires visiting documentation
- Operates from China; data residency concerns for some users versus US-based competitors
- Web interface blocked by geoIP in some regions
Stable Diffusion
- Generated images have lower resolution and quality at non-standard dimensions
- Struggles with complex multi-object prompts and text generation
- Poor rendering of human hands, limbs, and faces due to training data limitations
- Trained primarily on English-language descriptions, reinforcing Western cultural bias
- Requires significant GPU computational resources for local deployment

Answered from the vendors’ own pages
Stable Diffusion: Is Stable Diffusion truly free and open-source?
Yes. Stable Diffusion is released under the CreativeML Open RAIL-M license, allowing free use for both commercial and non-commercial purposes, and the code is open-source on GitHub.
SourceStable Diffusion: Can I use Stable Diffusion commercially for free?
Yes, if your organization has less than $1M annual revenue. Organizations exceeding $1M annually must obtain an Enterprise License from Stability AI.
SourceStable Diffusion: What are Stable Diffusion's image resolution limitations?
The base model was trained on 512x512 pixel images, and image quality degrades noticeably when deviating from this resolution. Newer models like SDXL support higher resolutions.
SourceStable Diffusion: Can I run Stable Diffusion locally on my computer?
Yes. Stable Diffusion is open-source and can run locally on compatible hardware, though it requires a GPU for reasonable performance.
