OpenAI is partnering with Cerebras to add 750MW of compute in 10B USD deal

If you are a founder, don't ever use Cerebras https://news.ycombinator.com/item?id=46707904

> By keeping computation and memory on a single wafer-scale processor, we eliminate the data-movement penalties that dominate GPU systems. The result is up to 15× faster inference, without sacrificing model size or accuracy.

If they actually put GPT5.2 into Cerebras I'm switching to OpenAI subscription instantly

Will be interesting to see how it is integrated. I assume it will be only a small fraction of openai's total inference.

Guessing the plan might be for voice AI. That stuff needs to be real snappy.

I hope all AI will reach 300ms response times, including 200 line diffs. Querying a million rows or informing user that a codebase is wrong used to take minutes but now happen instantly.

And the data centers created from this initiative will be net positive for the environment and communities, right? Right?

[whateverboat]

yes, because climate change simulations will become cheaper.
