DeepSeek-V3 Architecture Deep Dive: Multi-Head Latent Attention and DualPipe Parallelism
How DeepSeek-V3 achieved 671B parameters with only 37B activated per token, training on just 2,048 H800 GPUs for under $6 million.
The Architectural Breakthrough of Multi-Head Latent Attention
Traditional transformer KV cache size scales linearly with sequence length. DeepSeek-V3 introduces Multi-Head Latent Attention (MLA), compressing Key-Value states into low-dimensional latent vectors.
DualPipe: Overlapping Computation and Inter-GPU Communication
By scheduling forward and backward pipeline chunks concurrently, DualPipe eliminates network communication bubbles across cluster nodes without sacrificing throughput.
