GitHub – Deepseek-ai/DeepSeek-V3
We provide DeepSeek-V3, a strong Mixture-of-Experts (MoE) language model with 671B total specifications with 37B activated for each token. To attain efficient reasoning and economical training, DeepSeek-V3 adopts Multi-head Latent Attention (MLA) and DeepSeekMoE architectures, which were completely validated in DeepSeek-V2. Furthermore, DeepSeek-V3 leaders an auxiliary-loss-free technique for load balancing and sets a multi-token forecast training objective for more powerful efficiency. We pre-train DeepSeek-V3 on 14.8 trillion varied and top quality tokens, followed by Supervised Fine-Tuning and Reinforcement Learning phases to totally harness its abilities. Comprehensive assessments reveal that DeepSeek-V3 surpasses other open-source designs and achieves efficiency similar to leading closed-source models. Despite its excellent efficiency, DeepSeek-V3 requires just 2.788 M H800 GPU hours for its full training. In addition, its training process is extremely stable. Throughout the entire training procedure, we did not experience any irrecoverable loss spikes or carry out any rollbacks.
2. Model Summary
Architecture: Innovative Load Balancing Strategy and Training Objective
– On top of the effective architecture of DeepSeek-V2, we pioneer an auxiliary-loss-free technique for load balancing, which reduces the performance destruction that occurs from motivating load balancing.
– We examine a Multi-Token Prediction (MTP) objective and show it useful to model efficiency. It can likewise be utilized for speculative decoding for reasoning velocity.
Pre-Training: Towards Ultimate Training Efficiency
– We design an FP8 mixed accuracy training framework and, for the very first time, validate the expediency and effectiveness of FP8 training on an incredibly massive model.
– Through co-design of algorithms, frameworks, and hardware, we conquer the communication traffic jam in cross-node MoE training, almost accomplishing full computation-communication overlap.
This considerably boosts our training performance and lowers the training costs, enabling us to further scale up the model size without additional overhead.
– At an economical cost of just 2.664 M H800 GPU hours, we finish the pre-training of DeepSeek-V3 on 14.8 T tokens, producing the currently strongest open-source base design. The subsequent training phases after pre-training need only 0.1 M GPU hours.
Post-Training: Knowledge Distillation from DeepSeek-R1
– We introduce an innovative method to distill reasoning abilities from the long-Chain-of-Thought (CoT) model, specifically from among the R1 series designs, into basic LLMs, especially DeepSeek-V3. Our pipeline elegantly includes the verification and reflection patterns of R1 into DeepSeek-V3 and notably enhances its thinking efficiency. Meanwhile, we also keep a control over the output style and length of DeepSeek-V3.
