The Biden administration reportedly set to announce a new set of last-minute expansive chip export restrictions today.

It's a three-tiered system that would put new caps on AI chip curbs depending on the country and the company.

Deirdre Bosa has more in today's tech check. Deirdre, explain this for us, please.

I will. And in doing so, I'm also going to ask how successful have the current restrictions

been? The export ban did prevent China from getting the highest-end American chips, but it did

not stop China from catching up in the AI race, proving that necessity is the mother of invention.

Now, despite not having access to NvidiaVIDIA's best performing GPUs,

a Chinese research lab called DeepSeek

was able to build an AI model

using dumbed-down GPUs

that beat OpenAI's GPT4 on certain benchmarks.

That just shocked the AI community.

Here's what perplexity CEO,vin Sreenabest told me.

But the reality is some of the details in Deep Sequit 3 are so good that I wouldn't

be surprised if meta took a look at it and incorporated some of that in Lama 4, right?

So advanced that our best american companies could use it as a blueprint that is a shocking

statement in other words the existing chip restrictions they did nothing to slow down china's pace

that only made them more creative and more efficient they backfired other chinese labs are

also making major strides and efficiency

with limited resources. There's Kaifu Lee's 0.01.AI and Alibaba's QN. There's others. The export ban on

China has also led to smuggling and loopholes. A report from the information said that

TikTok owner Bite Dance and other Chinese companies rented high-end
