DeepSeek-V3
Open-weight 671B mixture-of-experts language model matching proprietary frontier systems
DeepSeek-V3 is an open Mixture-of-Experts language model with 671B total parameters and 37B activated per token. It delivers coding, math, and conversational performance comparable to top closed models like GPT-4o and Claude 3.5 Sonnet. It is accessible through a free web chat, an OpenAI-compatible API, and open model weights on Hugging Face.
What it's for
- Run complex coding and debugging tasks across multiple programming languages
- Solve advanced mathematical problems and multi-step reasoning puzzles
- Deploy a large-scale open-weight model locally or on private cloud infrastructure
- Integrate an economical OpenAI-compatible chat API into developer applications
Features
- Mixture-of-Experts (MoE) architecture activating 37B out of 671B parameters per token
- 128K context window length evaluated on needle-in-a-haystack tasks
- Trained with Multi-head Latent Attention (MLA) and native FP8 mixed precision
- Knowledge distillation from DeepSeek-R1 reasoning models
- Inference support via vLLM, SGLang, LMDeploy, and TensorRT-LLM
- Free web chat interface with built-in search and reasoning toggles
