The way I am doing the math with my Max subscription and assuming DeepSeek API prices, it is still x5 times cheaper. So either DeepSeek is losing money (unlikely) or Anthropic is losing lots of money (more likely). Grok kinda confirms my suspicions. Assuming DeepSeek prices, I've probably spent north of $100 of Grok compute. I didn't pay Grok or Twitter a single cent. $100 is a lot of loss for a single user.
