Midjourney is the leading closed-source AI image generation platform, operating through Discord and a redesigned web interface at alpha.midjourney.com. As of mid-2026, the platform launched V8 Alpha on March 17, 2026—a complete rewrite delivering 5x faster generation, native 2K HD images via the --hd parameter, dramatically improved text rendering (readable street signs, product labels, typography), and superior prompt understanding. V8 introduces new creative parameters including --chaos, --weird, --exp, and --raw for experimental control. Premium features cost 4x standard generation: --hd, --q 4 (enhanced coherence), style references, and moodboards. Pricing is subscription-based with GPU-hour allocations: Basic ($10/month, ~3.3 fast hours, no Relax Mode), Standard ($30/month, 15 fast hours + unlimited Relax), Pro ($60/month, 30 hours + Stealth Mode), Mega ($120/month, 60 hours + Stealth). Annual billing offers 20% savings. Relax Mode provides unlimited but slower generations after fast hours are depleted (Standard and above). Extra GPU hours cost ~$4/hour. There is no public API—Midjourney remains a closed ecosystem.
