Midjourney
- +Distinctive, high-aesthetic art style that many users prefer for illustration and concept work
- +Mature editing toolkit (inpainting, pan/zoom, upscale, Omni Reference) plus image-to-video (V1)
- +Simple flat-rate subscription starting at $10/month with no per-image metering on Relax mode (Standard and up)
- -An assistant, not an autonomous agent: the human prompts, curates, and iterates on every output
- -No free tier and no API for programmatic generation (web app and Discord only)
Stable Diffusion
- +Open weights you can download and run locally on consumer hardware, no per-image fee for self-hosting
- +Huge ecosystem (ComfyUI, Diffusers, AUTOMATIC1111, ControlNet, LoRAs) plus fine-tuning and customization
- +Permissive Community License: free for non-commercial use and for commercial use under $1M annual revenue
- -An assistant, not an autonomous agent: the human prompts, curates, and iterates on every output
- -Self-hosting requires a capable GPU and technical setup (the easy path is third-party apps or the hosted API)
