Which should you use?
Benchmarks can only tell you so much. The honest answer for any real workload is: send the same prompt to both and read the two answers yourself.

FAQ
Midjourney vs Stable Diffusion is a side-by-side comparison of two AI models. Midjourney is built by Midjourney, and Stable Diffusion by Stable Diffusion. Send them the same prompt at /chat/compare/ and read both answers side by side.
Mixed — Midjourney and Stable Diffusion don't have the same pricing. Self-hosted open-source models on Free.ai are free to use up to your daily token allowance; premium external models routed through third parties require purchased tokens (starting at $5 for 200K).
Depends on your workload. Send the same prompt to both at /chat/compare/ and judge the two answers directly — benchmarks can only tell you so much. The AI Arena also collects community votes on blind responses if you want a broader signal.
Depends on the model. Free.ai's self-hosted open-source models are free without sign up (up to the daily token allowance). Premium external models need a purchase to use.
The compare tool sends the same prompt to Midjourney and Stable Diffusion in parallel and streams both responses side by side. Each panel has its own conversation history, so you can follow up differently on each side.
Yes. Each panel has its own model picker — change Midjourney or Stable Diffusion to any of 370+ models at any time. The conversation history on each side is preserved.
Free.ai bills in tokens, not per-message. A typical chat turn on Midjourney uses your daily allowance; on Stable Diffusion, your daily allowance. $5 buys 200,000 tokens and they never expire. Self-hosted open-source models are free up to your daily allowance.
Midjourney supports a large context window of context; Stable Diffusion supports a large context window. Context window is how much text the model can read in a single conversation before older messages start being trimmed.
Yes. Signed-in users have their compare sessions saved automatically — see the sidebar on /chat/compare/ for past comparisons. Each comparison stores both sides (Model A and Model B) independently so you can revisit exact responses.
Only for external models. Midjourney runs on Midjourney's servers (premium); your prompt is routed there through our external-model gateway when you use this pair. Self-hosted open-source models like Qwen, Mistral, DeepSeek, FLUX, Kokoro, and Whisper run on Free.ai's own GPUs — nothing leaves our infrastructure.
Yes. Both Midjourney and Stable Diffusion are accessible through the Free.ai API — one Bearer token, OpenAI-compatible chat/completions. Paid models require purchased tokens (no API access from the daily free pool).
Check each model's page under /apps/ for specs. For head-to-head quality signal, the /arena/ leaderboard ranks models by blind community votes. For your own workload, sending the same prompts through the compare tool is the most reliable signal.
