$4.20 / callWhen to use MiniMax Voice Design
Where this model earns its cost — and where it doesn't.
MiniMax Voice Design creates a synthesized voice profile from a text prompt. It returns a voice_id that works with any MiniMax HD or Turbo speech endpoint. The model operates on a per-call basis with a flat charge for each designed voice.
On Kyma, the model runs through the standard OpenAI-compatible base URL using a single API key. Every request includes automatic failover if a serving path degrades, and responses report exact costs in usage.cost alongside the active model in the X-Kyma-Model header. Prompt caching applies to repeated prefixes at a 10% rate, and new accounts include a $0.50 signup credit.
The model accepts text input and outputs audio metadata rather than continuous speech streams. It does not support reasoning, vision, or structured outputs, and operates with a 1,000-token context window. It is optimized for voice design rather than direct text-to-speech generation.
