How to Self-Host DeepSeek R1: Hardware, Setup, and Privacy Guide (2026)

DeepSeek R1 is an advanced open-weight model that rivals OpenAI's capabilities in reasoning tasks, but its API usage involves data privacy concerns as all data is stored on servers in China, subject to Chinese regulations. Alternatives to using the API include self-hosting the model, which allows for data sovereignty as the data remains on one's infrastructure, or opting for managed private deployment with companies like PremAI, which offer deployment within a Virtual Private Cloud (VPC) under Swiss jurisdiction with no data retention. The model is available in different variants, with the flagship being a 671 billion parameter Mixture-of-Experts model, while smaller distilled models provide a balance between performance and resource requirements. The 32B Qwen distill model is recommended for those starting out, as it fits on a single RTX 4090 at INT4 quantization without commercial restrictions. Deployment options include using vLLM for community support or SGLang for better low-concurrency performance, with considerations of costs and infrastructure management influencing the decision between self-hosting, managed deployment, or using the API. The commercial use of DeepSeek R1 is permissible under its licensing terms, though those considering the model must weigh the costs and potential technical challenges associated with running the models on their own hardware.
