Perplexity: R1 1776

perplexity/r1-1776

Model weights

R1 1776 is a version of DeepSeek-R1 that has been post-trained to remove censorship constraints related to topics restricted by the Chinese government. The model retains its original reasoning capabilities while providing direct responses to a wider range of queries. R1 1776 is an offline chat model that does not use the perplexity search subsystem.

The model was tested on a multilingual dataset of over 1,000 examples covering sensitive topics to measure its likelihood of refusal or overly filtered responses. Evaluation ResultsOpens in new tab Its performance on math and reasoning benchmarks remains similar to the base R1 model. Reasoning PerformanceOpens in new tab
