DeepSeek R1 is an open-source large language model (LLM) for conversational AI, coding, and problem-solving. It recently outperformed OpenAI's flagship reasoning model on several benchmarks. To run DeepSeek R1 locally, users can use Ollama, a tool that simplifies the complexities of AI model deployment by offering pre-packaged model support, cross-platform compatibility, and simplicity and performance. The main DeepSeek R1 model is large, but users can also download smaller "distilled" variants, such as 1.5B or 7B, which are optimized for developers who want lighter compute requirements or faster responses. Running DeepSeek R1 locally keeps data private and allows for faster responses without worrying about external dependencies. The tool can be integrated into any workflow and is suitable for commercial use.
