Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Resemble AI
- The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
- Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.
- SSO and org-wide security features are only available starting on the $1,000/month Business plan.
- Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.
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
Resemble AI: What does Resemble AI cost?
Resemble AI offers a free Flex pay-as-you-go plan, a Team plan at $350/month, a Business plan at $1,000/month, and custom Enterprise pricing, with lower monthly rates available on annual billing.
SourceStable 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.
SourceResemble AI: Is there a free plan, and what are its limits?
The Flex plan is free with 1 team seat, no credit card required, and pay-as-you-go usage where purchased credits never expire.
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.
SourceResemble AI: How is usage metered?
Usage is billed per second or per image processed for detection (e.g. $0.035/sec for audio detection on Flex, dropping to $0.015/sec on Team and Business), with separate rates for video and intelligence analysis.
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.
