Where this model earns its cost — and where it doesn't.
ElevenLabs v3 generates speech from text input with support for emotional range, inline audio tags, and natural delivery across more than 70 languages. It operates at a medium speed tier with a balanced cost profile and a 5,000-token context window.
On Kyma, the model runs through an OpenAI-compatible endpoint with automatic failover to maintain delivery if a serving path degrades. It supports prompt caching, which bills repeated prompt prefixes at 10% of the standard input rate. Responses return exact billing data in usage.cost and identify the executed model via the X-Kyma-Model header.
The model does not support reasoning, vision, or structured outputs. It is strictly a speech generation engine, so it will not process images, execute code, or return JSON schemas.
