DeepSeek claims that the cold-start data is from DeepSeekV3, which is the model that has the $5.5M pricetag. If that data were actually the output of o1 (a model that had a much higher training cost, and its own RL post-training), that would significantly change the narrative of R1's development, and what's possible to build from scratch on a comparable training budget.
