Stable Diffusion
Best free planThe open-source image model you can run and shape yourself
Our verdict
Hard to beat on price and control — but the learning curve is real, and a beginner will get better results from a hosted tool.
Stable Diffusion is the open-weights family behind most self-hosted image generation: run it on your own GPU, fine-tune a LoRA on your own data, and pick from thousands of community models and interfaces. Quality depends heavily on the checkpoint and sampler you choose.

Alternatives to Stable Diffusion
Midjourney
Atmospheric AI art from the generator digital artists love most
Midjourney remains the benchmark for sheer image beauty: painterly light, coherent compositions and a house style that flatters almost any prompt. Generation happens in Discord or on the web, and there is no official API — it is a tool for making images, not a platform to build on.
FLUX
Photoreal open-weights models from the original Stable Diffusion team
FLUX.1 from Black Forest Labs closed much of the gap to Midjourney: sharp detail, dependable hands and strong prompt adherence. The [schnell] variant is open for commercial use, while [dev] carries a non-commercial licence you need to read before shipping anything.
DALL·E
OpenAI's image generator, built right into ChatGPT
DALL·E 3 generates from plain conversational prompts and lives inside ChatGPT, so you refine images by talking to it rather than fighting prompt syntax. It is less stylistically distinctive than Midjourney, but excellent at literal, instruction-following images.
Ideogram
The best AI image generator at putting text in images
Ideogram's standout skill is rendering legible text — logos, posters, packaging mockups, memes — where other models produce gibberish. Beyond typography it is a solid general generator with a clean canvas and useful style presets.
