We’re expanding our partnership with @SpaceX, and will be scaling up on GB200 capacity in Colossus 2 throughout June.

Appreciate @elonmusk and the team helping us find good homes for the Claudes.

In the next few days we'll be ramping up Claude inference on Colossus.

Grateful to be partnering with SpaceX here. We are going to need to move a lot of atoms in order to keep up with AI demand, and there's nobody better at quickly moving atoms (on or off planet Earth)

Txs, it's been a rocky road on the Opus 4.7 API every morning these days.

At this rate, don't be surprised if Anthropic seizes all the compute in the US before the end of the year even that owned by OpenAI and Google just as happened with xAI.

How much capacity of Colossus 2 will you be using ? What will XAI be using?<br>Who will use Blackwell and Vera Rubin?@grok

This is just inference scaling.<br>GB200 were supposed to be used for training, for inference there are GB300
