Microsoft invested $1 billion OpenAI in 2019 and half of that amount was in Azure credits. I'm not sure about the most recent $10 billion investment but I wouldn't be surprised if a significant amount of it is in Azure credits as well. While that's not "free" (they exchanged equity for it), it's likely not an expense (or at least not an expense that they have to cover fully).
