Unified Audio Intelligence Platform
Kimi-Audio revolutionizes audio processing as a universal foundation model capable of handling diverse tasks within a single framework. This all-in-one solution eliminates the need for specialized models across different audio domains, providing unprecedented versatility for next-generation audio applications.

Breakthrough Architecture & Training
The model employs a novel hybrid architecture combining continuous acoustic vectors and discrete semantic tokens, processed through an LLM core with parallel heads. Pre-trained on over 13 million hours of diverse audio (speech, music, environmental sounds) and text data, it achieves state-of-the-art results across multiple audio benchmarks. This massive training scale enables robust audio reasoning and language understanding capabilities.
