The short version

  • Each has a real cost: Packer packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; Stable Diffusion generated images have lower resolution and quality at non-standard dimensions
  • They diverge on capability: Packer covers Image building, Stable Diffusion covers Text-to-image.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Packer

  • Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence

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

Stable 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.

Source
Stable 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.

Source
Stable 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.
