Routes each token through a subset of 37B active parameters from a total 671B parameter pool using DeepSeekMoE architecture, enabling inference cost and latency comparable to much smaller dense models while maintaining capability parity with larger models. Expert routing is learned during training and applied deterministically at inference time, reducing GPU memory requirements and per-token computation.

Unique: DeepSeekMoE architecture combines sparse expert routing with Multi-Head Latent Attention (MLA) to achieve 37B active parameters per token from 671B total, reducing inference cost by ~5.5x compared to dense 671B models while maintaining GPT-4o-level performance

Compresses multi-head attention mechanisms into latent space using learned projections, reducing memory overhead and computation of attention operations while maintaining semantic quality across 128K token sequences. MLA replaces standard multi-head attention's O(n²) memory complexity with a more efficient latent representation, enabling longer contexts on fixed GPU memory budgets.

Unique: Multi-Head Latent Attention compresses attention heads into learned latent space rather than computing full multi-head attention matrices, reducing memory complexity while maintaining 128K context capability — architectural innovation not widely adopted in other open-source models

vs alternatives: Enables 128K context processing with lower memory overhead than standard multi-head attention used in GPT-4 and Claude, making long-context inference more accessible on consumer-grade GPUs
