Technical Specifications and Architectural Innovations

DeepSeek-V3.2 is an open-weight large language model (LLM) released in late 2025, distinguishing itself as a hybrid reasoning LLM designed for high reasoning performance and efficient long-context processing 1. The model weights are made available under an MIT license on Hugging Face .

The core technical specifications of DeepSeek-V3.2 are summarized below:

Feature Specification Reference
Model Name DeepSeek-V3.2 1
Model Type Mixture-of-Experts (MoE) transformer
Total Parameters Approximately 685 billion
Activated Parameters Roughly 37 billion (per token)
Context Window 128,000 tokens
Output Lengths Base chat model: 4,000–8,000 tokens (default); Reasoning mode: 32,000+ tokens; Speciale model: 128,000 tokens 1
Input/Output Modality Text input, text output 2
Open-Weight Availability Yes, under an MIT license

The architecture of DeepSeek-V3.2 is identical to DeepSeek-V3.2-Exp 3 and builds upon the foundation of DeepSeek-V3 4. Key architectural innovations contribute to its performance and efficiency:

  1. DeepSeek Sparse Attention (DSA): This efficient attention mechanism significantly reduces computational complexity from O(L²) to approximately O(L·k) for long sequences, where L is the sequence length and k is the number of selected tokens . DSA utilizes a "lightning indexer" and token selector to dynamically choose relevant past tokens, thereby enhancing speed and memory usage during both training and inference 1. DSA is instantiated under Multi-Head Latent Attention (MLA) 3.
  2. Multi-Head Latent Attention (MLA): Carried over from earlier DeepSeek versions (V2, V3, R1) 5, MLA compresses key and value tensors into a lower-dimensional latent space for caching. This innovation reduces memory usage and is instrumental in enabling the extensive 128,000-token context window .
  3. Mixture-of-Experts (MoE) Architecture: DeepSeek-V3.2 employs an MoE design first introduced in V3. This architecture is central to its large parameter count and facilitates specialization across experts . It incorporates an auxiliary-loss-free strategy for load balancing, which aims to minimize performance degradation that can arise from load-balancing efforts 4.

The training methodologies for DeepSeek-V3.2 involve a multi-stage process:

  1. Continued Pre-training: This phase commences from DeepSeek-V3.1-Terminus, which already features an extended 128,000-token context length 3. It includes two distinct stages:
    • Dense Warm-up Stage: The lightning indexer component for DSA is initialized and trained over 1,000 steps using 16 sequences of 128,000 tokens each, totaling 2.1 billion tokens, with a learning rate of 10^-3 3.
    • Sparse Training Stage: In this stage, DSA is fully activated, and all model parameters undergo optimization. It involves selecting 2,048 key-value tokens per query token and training for 15,000 steps with 480 sequences of 128,000 tokens per step, accumulating 943.7 billion tokens, using a learning rate of 7.3 x 10^-6 3.
  2. Specialist Distillation: Reasoning skills from "long-thinking teachers" (models akin to DeepSeek-R1) are distilled into the base model using Reinforcement Learning (RL) . This process aims to preserve reasoning quality while enabling control over style and length for production use cases 6.
  3. Mixed RL Training: DeepSeek-V3.2 utilizes the Group Relative Policy Optimization (GRPO) algorithm 3. This stage integrates reasoning, agent, and human alignment training, balancing performance across diverse domains 3. Rewards are based on rule-based outcomes, length penalties, and language consistency for reasoning/agent tasks, along with a generative reward model for general tasks 3. GRPO updates feature several innovations, including an unbiased KL estimate , off-policy sequence masking for training stabilization , "Keep Routing" to preserve expert routing paths in MoE models , and "Keep Sampling Mask" for top-p/top-k sampling .
  4. Large-Scale Agentic Task Synthesis Pipeline: To enhance the integration of reasoning with tool use, a novel data generation pipeline was developed, creating over 1,800 environments and 85,000 complex prompts . This includes a "cold-start" phase and advanced synthesis methods to improve generalization and instruction-following in interactive environments 3.
  5. DeepSeek-V3.2-Speciale Variant: This high-compute variant is trained exclusively on reasoning data during its RL stage with a reduced length penalty, which facilitates the generation of longer responses . It also incorporates data and reward methodologies from DeepSeekMath-V2 to bolster its mathematical proof capabilities .
