Architectural Innovations

Mixture‑of‑Experts (MoE) and Multi‑Head Latent Attention

DeepSeek‑V3’s groundbreaking MoE architecture activates only
about 37 billion parameters per token. This approach contrasts with dense
models such as GPT‑4 that deploy all parameters on every input, leading to
significant computational overhead. Key innovations include:

• DeepSeekMoE: A dual‑expert design where shared experts manage universal patterns and routed
  experts focus on niche tasks. This results in a GPU memory usage reduction
  of up to 93.3% compared to traditional architectures.
• Multi‑Head Latent Attention (MLA): By compressing key‑value vectors during inference through low‑rank factorization, MLA slashes memory overhead and speeds up processing without sacrificing
  accuracy.

Training Breakthroughs

DeepSeek‑V3 also sets new standards in model training:

• FP8 Mixed Precision: The first ultra‑large model trained using FP8 precision, reducing GPU memory usage by 30% and accelerating training by 2.1 times.
• Multi-Token Prediction: Simultaneous token prediction improves long text coherence and cuts training time.
• Stability: Completing training in just 2.78 million H800 GPU hours with no unrecoverable loss spikes this model achieves its results at a fraction of the cost of competitors.
