According to @deepseek_ai, DeepSeek introduced token-wise compression combined with DeepSeek Sparse Attention (DSA) to deliver world-leading long‑context efficiency with sharply reduced compute and memory costs, and set 1M tokens as the default context across all official services. As reported by DeepSeek’s official announcement on X, the structural innovations target lower latency and lower total cost of ownership for long-context workloads such as multi-document RAG, long-form codebases, and enterprise archives. According to the same source, the move standardizes million-token windows for production, creating business opportunities for enterprises to consolidate retrieval, summarization, and compliance audit pipelines into a single pass, potentially cutting inference spend and hardware footprint.
