The short version

  • Only Stable Diffusion has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lambda Labs on demand capacity is first come access rather than guaranteed, so an instance type can be unavailable when needed; Stable Diffusion generated images have lower resolution and quality at non-standard dimensions
  • They diverge on capability: Lambda Labs covers NVIDIA GPUs, 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.

Lambda Labs

  • On demand capacity is first come access rather than guaranteed, so an instance type can be unavailable when needed
  • H100 pricing varies within a band, at $3.99 to $4.29 an hour per GPU, so the rate is not fixed
  • Reserved capacity is arranged by contacting the team rather than self serve
  • Prices are quoted before applicable tax

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.

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.
