Plain Language Accessible to non-experts
Imagine you're playing in a band, and each member needs to play the right notes at the same time. StreamMUSE is like a smart conductor, ensuring each musician plays the right note at the right time. It analyzes the sheet music, quickly calculates what each musician should play, and sends it to them at the right moment. This way, even with network delays, the band can maintain perfect synchronization.
ELI14 Explained like you're 14
Imagine you're playing a music game with friends, and you need to press the right buttons when the notes appear on the screen. StreamMUSE is like a super helper, telling you which button to press a few milliseconds before you need to. Even if the network is a bit slow, it has backup plans ready to keep your performance smooth. Isn't that cool?

Abstract
Language models (LMs) have become one of the most prominent paradigms in modern generative modeling. While making them faster has been the main focus of real-time deployment, speed alone is not enough. Many real-world applications, such as synchronized translation and voice synthesis, also require precise alignment between generation and external signals, both in terms of generation content and timing. We refer to this problem as \textit{frame-synchronous streaming inference}. To address it, we present StreamMUSE, an inference system that performs LM generation in response to an external signal stream within a client-server architecture. The client continuously sends high-frequency inference requests based on the most recent inputs and receives outputs synchronized to the external clock, while the server executes model inference. We demonstrate the framework through a live music accompaniment task, showing how real-time synchronization can be achieved across different deployment environments with varying round-trip latencies. We further model the relationship between system hyperparameters and round-trip latency, and evaluate how different environments affect optimal configurations to achieve real-time performance. Experimental results show a consistent correspondence between system real-time performance and music quality, demonstrating the effectiveness of the proposed framework. The project is open source.
