Fastest AI image models, measured
Every current text-to-image model timed on the same prompts at its default settings — median seconds per image, next to how voters rate its images and what one costs.
Updated September 23, 2026 · 20 models · methodology
As of September 23, 2026, Grok Imagine Image Quality by xAI is the fastest of the 20 text-to-image models in the BudgetPixel AI Image Arena, at 5.3s median per image (#11 for quality). The fastest of the top five for quality is Nano Banana 2 Lite at 15.4s (#4). The slowest is Midjourney Niji 7 at 107.0s.
No model is both faster and better rated than Grok Imagine Image Quality (5.3s, #11), Muse Image 1.0 (12.4s, #8), Nano Banana 2 Lite (15.4s, #4) and GPT Image 2.5 Flare (25.6s, #1) — each is the best-rated model at its speed.

Same prompts, same settings
Each model renders the arena's identical prompt suite at its default settings and resolution, one 1:1 image per prompt, so the times compare like for like.
Median, not best case
Time runs from the start of generation to the finished image. The median across every prompt means one slow or lucky run does not move it.
Quality and price beside it
Quality is the model's overall rank from blind votes; price is the standard credit price of one default image (1,000 credits are one dollar).
FAQ
