DeepSeek V4 has introduced a novel compressed attention mechanism that significantly slashes KV-cache memory usage by 98%. This innovation allows the model to maintain a 1 million-token context window while drastically improving efficiency. The architecture compresses attention along the sequence dimension, a departure from traditional methods, and employs techniques like CSA, HCA, and KV sharing to revolutionize LLM performance. AI
