DeepSeek open-sources DeepInfer inference engine with advanced caching

DeepSeek has open-sourced DeepInfer, an inference engine designed for production deployment. This toolkit, built upon vLLM with contributions from SGLang and TRRTLLM, offers advanced features like 72-hour prompt caching and supports distributed inference across NVIDIA and Huawei Ascend platforms. While the core engine is open source, DeepSeek has noted that certain components, such as optimized KV-cache management and load balancing, are not yet fully released due to internal infrastructure dependencies. The release highlights significant performance claims, including serving 155 trillion tokens per day with a reported 80% inference margin and an 81-day payback period. AI

IMPACT Accelerates open-source inference capabilities, potentially lowering costs and increasing accessibility for large-scale AI deployments.

RANK_REASON Open-source release of a production inference engine by a frontier lab (DeepSeek) with significant performance claims.
