# Models docs URL migration - waves → models, version dropdown flattened

> The Models product now lives under /models/ on the docs site, replacing the older /waves/ prefix.

The Models product now lives under `/models/` on the docs site, replacing the older `/waves/` prefix. The version dropdown is also gone. There is only one active version (v4.0.0), and it is served from a flat URL - `/waves/v-4-0-0/documentation/text-to-speech-lightning/streaming` becomes `/models/documentation/text-to-speech-lightning/streaming`.

Every old URL 301-redirects to its new equivalent. Legacy v2.2.0 and v3.0.1 bookmarks (retired earlier) also land on the same flat `/models/*` paths. Bookmarks, external links, and search-indexed pages keep resolving.

API endpoints and SDK identifiers are unchanged. `POST /waves/v1/tts`, `POST /waves/v1/chat/completions`, `wss://api.smallest.ai/waves/v1/stt/live`, and the `waves` OpenAPI namespace on the SDK all still work exactly as before. Only docs URLs moved.
