DeepSeek-R1 is a fully open-weight large language model (LLM) achieving close performance to the state-of-the-art reasoning models like o1 and o3-mini. A major issue limiting R1's utility is its refusal to respond to sensitive topics, especially those that have been censored by the Chinese Communist Party (CCP).
At Perplexity, we aim to provide accurate answers to all user queries. This means that we are not able to make use of R1's powerful reasoning capabilities without first mitigating its bias and censorship. We therefore used post-training to offer an unbiased, accurate, and factual R1 model.
