DeepSeek-V3 is the third-generation open-source large language model developed by DeepSeek, with 671 billion parameters, a mixture-of-experts architecture, and a 128K context length. It is completely free and supports commercial use.
Yes. DeepSeek-V3 is open-sourced under the MIT license, allowing free commercial use with no registration or royalty payments required; the model code and weights are publicly available.
You can obtain the open-source code from GitHub or download the model from Hugging Face, supporting deployment frameworks such as SGLang, LMDeploy, and vLLM. Requires NVIDIA A100/H100-class GPUs and about 700GB of storage.
Key advantages include the 671-billion-parameter scale, 128K ultra-long context, an efficient architecture that activates only 37 billion parameters per inference, and strong performance in code and math tasks, on par with mainstream closed-source models.
Particularly well-suited for high-complexity reasoning tasks, including code generation, math problem solving, long document analysis, multilingual processing, and enterprise-grade RAG scenarios, with strong performance in specialized domains.
Recommended hardware includes NVIDIA A100/H100 or AMD GPUs, 32GB+ system memory, about 700GB of storage, Linux support, and quantization techniques to reduce GPU VRAM requirements.
