Where each one falls short

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

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

Windsurf

  • Recently rebranded to Devin Desktop, creating product identity confusion
  • Cascade agent reached end-of-life on July 1, 2026, requiring migration to Devin Local
  • Free tier quota runs out quickly for active developers, within a couple days of coding
  • Pricing increased significantly in March 2026 overhaul, moving from credit-based to daily/weekly quotas
  • OpenAI acquisition raises concerns about long-term product direction diverging from Codeium's vision
