# FLUX AI vs Stable Diffusion

The clearest difference is monetization model: Stable Diffusion at free with in-app purchases against FLUX AI's subscription. Stable Diffusion also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). FLUX AI's advantage is review sentiment (46% vs 22%) and chart position (#184 vs unranked). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. FLUX AI sells 6 in-app purchases, starting at $4.99 per 7 days and Stable Diffusion sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

FLUX AI ships an update every 3 weeks, Stable Diffusion weekly. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
