## AI overview

Heroku increased the default maximum compressed app slug size from 500MB to 1GB and raised build compile timeouts. The update supports applications with large dependencies, while larger slugs may increase dyno boot times.

## Source excerpt

Modern applications, especially those leveraging AI and data-heavy libraries, need more room to breathe. To support these evolving stacks and reduce developer friction, we've increased the default maximum compressed slug size from 500MB to 1GB. Understanding app slugs and deployment App slugs are the container build artifacts produced by Heroku Buildpacks and run in dynos.
