This is Bloomberg Tech.

Thinking Machines Lab, the AI startup founded by former OpenAI executive Mira Marati, it could become one of the most valuable private companies less than a year after it launched.

According to sources, the startup is in talks to raise funding at a $50 billion valuation, quadrupling its value from July.

Let's get more from Bloomberg's Rachel Metz, who worked on this story with our very own Ed Ludlow and Shereen Khafari.

Is there fundamental growth that is vindicating this sort of 50 billion?

Or is it on the backing that she was there in such a leadership position over at OpenAI?

When we broke the story, people on social media kind of blew up and they were saying, oh, that would be $25 billion per blog post because the company's only ever done two blog posts.

But we did get the sense that this is Mira Marati, right?

That she is out there talking to investors about this.

It's her.

She's the face of it.

Explain to our audience who she is, why she's important, and I guess the intellectual capital that she gives that place.

Dig into that talent, Rachel, because she actually drew over with her an awful lot of ex-OpenAI, well, actual co-founders came with her.

And again, the reason this is extraordinary, it was only February that they kind of came into existence publicly.

July raised it a $12 billion valuation.

Now, November talks for $50 billion valuation, maybe more.

Bloomberg's Rachel Metsch, thank you very much.

Turning to media, Paramount, Netflix and Comcast are eyeing potential bids for Warner Brothers Discovery.

Meanwhile, the company has amended CEO David Zaslav's contract to...

to secure his pay in the event of a sale.
