It's the cost comparison with O1, both to train and run (per their pricing), that is causing most of the shock, perhaps as well as the fact that it's a GPU poor Chinese company that has caught up with O1, not a US one (Anthropic, Google, Meta, X.ai, Microsoft). The fact that it's open weights and training is fairly detailed in the paper they released is also significant.

The best comparison for R1 is O1, but given different training data, hard to compare outside of benchmarks. At the moment these "reasoning models" are not necessarily the best thing to use for non-reasoning tasks, but Anthropic have recently indicated that they expect to release models that are more universal.
