$0.07 / 1K charWhen to use MiniMax Speech HD
Where this model earns its cost — and where it doesn't.
MiniMax Speech HD converts text into high-quality audio across multiple languages. It delivers expressive voice synthesis with a 5,000-token context window and is optimized for strong audio quality at a cheap tier.
On Kyma, the model runs through an OpenAI-compatible endpoint using a single API key. Every request includes automatic failover if a serving path degrades, and responses return exact billing data in usage.cost alongside an X-Kyma-Model header. Prompt caching is supported, billing repeated prefixes at this model's cached input rate.
The model does not support reasoning, vision, or structured outputs. It operates at a medium speed tier, making it suitable for batch processing and asynchronous audio pipelines rather than low-latency conversational applications.
