Generate high-quality audio from text
Real-time audio streaming for low latency

## Key Features
`kugel-3` is the canonical production model for natural prosody, clean brand voices, multilingual TTS, streaming, and `break` tags.
Legacy IDs such as `kugel-2.5` and `kugel-2-turbo` remain accepted for backwards compatibility. Use `kugel-3` for new integrations.
Stream audio chunks as they're generated for the lowest possible latency. Perfect for LLM integrations where text arrives token by token.
Create custom voices from audio samples. Clone any voice with just a few seconds of reference audio.
Multilingual single model — 39 languages including DE, EN, FR, ES, IT, NL, PT, PL, RU, ZH, JA, KO, AR. See the [TTS endpoint reference](/api-reference/tts/generate) for the full list.
## Available Models
Use `kugel-3` for new integrations. See [Models](/models) for the current model reference.
| Model | Best for |
| --------- | ------------------------------------------------------------------------------------ |
