Company Description
GitHub – Deepseek-ai/DeepSeek-V3
We present DeepSeek-V3, a strong Mixture-of-Experts (MoE) language design with 671B overall specifications with 37B activated for each token. To attain efficient inference and cost-effective training, DeepSeek-V3 embraces Multi-head Latent Attention (MLA) and DeepSeekMoE architectures, which were completely verified in DeepSeek-V2. Furthermore, DeepSeek-V3 leaders an auxiliary-loss-free technique for load balancing and sets a multi-token forecast training goal for more powerful efficiency. We pre-train DeepSeek-V3 on 14.8 trillion varied and high-quality tokens, followed by Supervised Fine-Tuning and Reinforcement Learning phases to totally harness its capabilities. Comprehensive assessments expose that DeepSeek-V3 outperforms other open-source designs and attains 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 remarkably steady. Throughout the entire training procedure, we did not experience any irrecoverable loss spikes or perform any rollbacks.
2. Model Summary
Architecture: Innovative Load Balancing Strategy and Training Objective
– On top of the efficient architecture of DeepSeek-V2, we leader an auxiliary-loss-free strategy for load balancing, which decreases the performance deterioration that emerges from motivating load balancing.
– We investigate a Multi-Token Prediction (MTP) goal and prove it helpful to design performance. It can likewise be used for speculative decoding for reasoning acceleration.
Pre-Training: Towards Ultimate Training Efficiency
– We create an FP8 mixed accuracy training structure and, for the first time, validate the feasibility and effectiveness of FP8 training on an exceptionally large-scale model.
– Through co-design of algorithms, frameworks, and hardware, we get rid of the interaction bottleneck in cross-node MoE training, almost achieving full computation-communication overlap.
This substantially enhances our training effectiveness and minimizes the training costs, enabling us to even more scale up the design size without extra 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 presently strongest open-source base design. The subsequent training stages after pre-training require just 0.1 M GPU hours.
Post-Training: Knowledge Distillation from DeepSeek-R1
– We present an innovative method to boil down reasoning abilities from the long-Chain-of-Thought (CoT) design, particularly from one of the DeepSeek R1 series designs, into standard LLMs, particularly DeepSeek-V3. Our pipeline elegantly incorporates the verification and reflection patterns of R1 into DeepSeek-V3 and notably improves its thinking efficiency. Meanwhile, we also maintain a control over the output style and length of DeepSeek-V3.
