# API Reference: OpenAPI mode is now the default

LLM index: /llms.txt
Description: The Next example now ships with the faster OpenAPI experience, plus a tighter docs/API switcher.

## What shipped

The Next example now uses the Fumadocs OpenAPI renderer by default, which keeps the API reference inside the same overall docs experience instead of dropping into a separate shell.

## Why it matters

- Navigation between documentation and API reference feels much faster.
- The shared theme carries through more cleanly.
- Route generation is simpler for new projects.

## Small improvements

- The docs/API switcher stays in the familiar dropdown style.
- Remote specs continue to work for quick demos.
- Generated routes are cleaner for new scaffolds.
