Recently, the VITA-MLLM team announced the launch of VITA-1.5, an upgraded version based on VITA-1.0, aimed at enhancing the real-time and accuracy of multimodal interaction. VITA-1.5 not only supports English and Chinese but also achieves significant improvements in multiple performance metrics, providing users with a smoother interaction experience. In VITA-1.5, the interaction delay has been greatly reduced from 4 seconds to just 1.5 seconds, making it almost imperceptible for users during voice interactions.
