Midjourney

Midjourney is an AI system capable of generating images from text descriptions and prompts. Key facts:

• Uses a text-to-image diffusion model trained on millions of images
• Available through Discord bot with tiered subscription plans
• Produces high-quality, artistic images tailored to text prompts
• Allows image editing, variations, animated images, and more
• Opened up API access and model weights in November 2022

Midjourney relies on a type of deep neural network called a diffusion model. This allows high-resolution image generation that has rapidly improved in quality and capabilities since the bot's introduction in 2021.

Features like "/imagine", "/variation", and "/edit" give users creative control over generating images tailored to prompts. Midjourney also pioneered "outpainting" to extend and expand images. The bot has fostered online communities around AI art on Discord.

There are concerns about copyright, mature content, and Midjourney replacing human artists. But the system showcases the potential for AI to enhance creativity and expand access to art.
