DeepSeek-R1-0528 is a mixture-of-experts model with 671B total parameters, of which 37B are active for each token. DeepSeek lists a context window of 128K tokens. The model takes text input. The weights are released under the MIT license, which allows commercial use. The official weights on Hugging Face take about 1,369 GB. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
