The short version

  • Only Stable Diffusion has a free tier, so it costs nothing to try first.
  • Each has a real cost: Midjourney subscription tiers as captured 29 December 2023 ranged from $10/month (3.3 Fast GPU hours) to $120/month (60 Fast GPU hours), with extra GPU time at $4/hour, and companies earning over $1,000,000/year in gross revenue were required to use the Pro plan; Stable Diffusion generated images have lower resolution and quality at non-standard dimensions
  • They diverge on capability: Midjourney covers Style transfer, Stable Diffusion covers Image-to-image.
