One thing I (intuitively) don't doubt - that they spent less money for developing R1 than OpenAI spent on marketing, lobbying and management compensation.
P.S. - clarification: I mean not referring to talent at OpenAI. And yes I have very little doubt talent at DeepSeek is a lot cheaper than the things I listed above for OpenAI. I would be interested in a breakdown of the cost of OpenAI and seeing if even their technical talent costs more than the things I mentioned.
