That's definitely costing them more than running it on their own hardware, but it doesn't mean AI is costing them more than the AI startups. Anthropic for example is already paying SpaceX 1.25 Billion a month for compute, and has agreed to pay Google 200 billion over the next 5 years for access to Google's compute and TPU chips.

Google's deal with xAI specifically lets them terminate the deal with 90 days notice after the end of the year. Google is also investing heavily in building new data centers with their hardware. I'm assuming this deal means they've eclipsed their current TPU capacity, and are just looking for a short term bandaid until they can catch up with their new constructions.

Anthropic is doing the same too. SpaceX over here providing the shovels and pans for the modern day gold rush, sheesh.
