GitHub – Deepseek-ai/DeepSeek-V3
We present DeepSeek-V3, a strong Mixture-of-Experts (MoE) language design with 671B overall criteria with 37B triggered for each token. To attain effective inference and affordable training, DeepSeek-V3 embraces Multi-head Latent Attention (MLA) and DeepSeekMoE architectures, which were thoroughly verified in DeepSeek-V2. Furthermore, DeepSeek-V3 leaders an auxiliary-loss-free method for load balancing and sets a multi-token forecast training objective for more powerful efficiency. We pre-train DeepSeek-V3 on 14.8 trillion diverse and top quality tokens, followed by Supervised Fine-Tuning and Reinforcement Learning phases to totally harness its capabilities. Comprehensive evaluations reveal that DeepSeek-V3 outperforms other open-source designs and attains performance similar to leading closed-source designs. Despite its excellent efficiency, DeepSeek-V3 needs just 2.788 M H800 GPU hours for its full training. In addition, its training procedure is incredibly stable. Throughout the whole 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 technique for load balancing, which lessens the efficiency deterioration that emerges from motivating load balancing.
– We examine a Multi-Token Prediction (MTP) objective and prove it beneficial to model performance. It can also be utilized for speculative decoding for reasoning velocity.
Pre-Training: Towards Ultimate Training Efficiency
– We create an FP8 blended precision training structure and, for the very first time, validate the expediency and effectiveness of FP8 training on an incredibly large-scale design.
– Through co-design of algorithms, structures, and hardware, we get rid of the communication traffic jam in cross-node MoE training, nearly achieving full computation-communication overlap.
This substantially enhances our training performance and decreases the training costs, allowing us to even more scale up the design size without extra overhead.
– At a cost-effective expense of just 2.664 M H800 GPU hours, we complete the pre-training of DeepSeek-V3 on 14.8 T tokens, producing the presently strongest open-source base model. The subsequent training phases after pre-training require only 0.1 M GPU hours.
Post-Training: Knowledge Distillation from DeepSeek-R1
– We present an ingenious approach to distill thinking abilities from the long-Chain-of-Thought (CoT) design, specifically from among the DeepSeek R1 series designs, into basic LLMs, particularly DeepSeek-V3. Our pipeline elegantly integrates the verification and reflection patterns of R1 into DeepSeek-V3 and especially improves its thinking performance. Meanwhile, we likewise keep a control over the output design and length of DeepSeek-V3.
