$0.09 / 1K charWhen to use MiniMax Speech Turbo
Where this model earns its cost — and where it doesn't.
MiniMax Speech Turbo converts text input into audio output with a focus on speed and efficiency. It supports multiple languages and operates in the cheap cost tier and fast speed tier, making it suitable for applications that prioritize low latency and high request volume over studio-grade fidelity.
On Kyma, the model is accessible via an OpenAI-compatible endpoint using a single API key. It supports prompt caching, which applies a 90% discount to repeated input prefixes, and includes automatic failover to reroute requests if a serving path degrades. Responses return exact billing metrics in the usage.cost field and report the active model in the X-Kyma-Model header.
The endpoint does not support reasoning, vision, or structured outputs, and it is strictly a speech generation interface. It is designed for scalable deployments where consistent throughput and fast delivery are the primary requirements.
Real-time voice agents
Generates rapid audio responses for interactive conversational systems.
Bulk narration pipelines
Processes large volumes of text into speech efficiently.
Conversational AI backends
Delivers fast, multilingual audio output for chat and voice assistants.
Scalable text to speech
