Leonardo generates 4.5M images daily with Next.js and Vercel

Leonardo.Ai, which generates over 4.5 million images daily, migrated its web application to Vercel and reduced build times from over 10 minutes to as little as 2 minutes, and cut page load times by 95% through improved caching and CDN performance.

The move also enabled the team to iterate and launch new products in 1–4 weeks instead of months.
