DeepSpeed-FastGen is built to leverage continuous batching and non-contiguous KV caches to enable increased occupancy and higher responsivity for serving LLMs in the data center, similar to existing frameworks such as TRT-LLM, TGI, and vLLM. In order to achieve a new level of performance, DeepSpeed-FastGen introduces SplitFuse which leverages dynamic prompt and generation decomposition and unification to further improve continuous batching and system throughput.
