## Default Model is now `saaras:v3`

Model APIs

The `/speech-to-text` REST and Batch endpoints now default to `saaras:v3` when no `model` is specified (previously `saarika:v2.5`). Requests that omit `model` will use the new model and respect the `mode` parameter (`transcribe`, `translate`, `verbatim`, `translit`, `codemix`). To keep the previous behavior, pass `model="saarika:v2.5"` explicitly. `saarika:v2.5` remains available as a legacy model.

## Translate via `/speech-to-text`

Model APIs

The dedicated `/speech-to-text-translate` endpoint is now legacy (`saaras:v2.5`). For state-of-the-art translation, use the `/speech-to-text` endpoint with `model="saaras:v3"` and `mode="translate"`.
