Overview

This model converts text input into audio output with support for expressive voice profiles and brand-safe delivery. It operates in a balanced cost tier with medium generation speed and is designed specifically for speech synthesis. On Kyma, it runs through an OpenAI-compatible endpoint using a single API key. This model does not support prompt caching. Requests automatically failover to healthy serving paths if degradation occurs, and exact billing details are returned in the usage.cost field. The model does not support reasoning, vision, or structured outputs. It accepts text input only, has a 5,000-token context window, and is strictly an audio generation endpoint.

Specs

Pricing

Billed per character of input text. Every request reports its exact cost in usage.cost; the full media price list is on Pricing.

Use this when

  • Multilingual Voiceover Generation — Produce localized audio tracks for videos and presentations across 29 supported languages.
  • Brand Narrative Synthesis — Maintain consistent, brand-safe vocal delivery across marketing and onboarding content.
  • Long-Form Storytelling Audio — Render expressive narration for audiobooks, podcasts, or interactive media.
  • Text Translation to Speech — Convert written translations into natural-sounding audio for accessibility or localization workflows.

Not ideal for

Do not use this model for tasks requiring text reasoning, structured JSON output, or ultra-low latency streaming, as it only generates audio and operates at a medium speed tier.

FAQ

Does this model support prompt caching on Kyma? No, this model does not support prompt caching. Can I use a single API key for this and other models? Yes, Kyma provides one API key for all models and routes requests through an OpenAI-compatible base URL. How does Kyma handle request failures for this model? Every request includes automatic failover, so if a serving path degrades, your request is silently rerouted to a healthy path without manual intervention.
