1 prediction · 2 assertions · 2 opinions · 3 disclosures · every statement was checked. The prediction and assertions are the 3 claims: statements the public record can support or contradict. 2 are resolved, and 1 names no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Karan argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

Their most notable supported claim

Assertion Supported
Goel: Cartesia's Sonic TTS engine reduces typical voice latency by 150ms
“Even with what we've done with Sonic, we're already kind of shaving off, like, a 150 milliseconds off of you know, what they typically use.”

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Karan Goel on measured tape to publish a rate. This says nothing about how they speak.

Prediction Not checkable as stated
Goel: AI models generating real-time data will replace traditional graphics engines
“In the future, like you will be essentially replacing, you know, graphics and rendering with essentially models that are outputting streams of data. In real time.”
Karan Goel Jun 27, 2024 ▶ 15:10 No Priors Ep. 70 | With Cartesia Co-Founders Karan Goel & Albert Gu
Opinion
Goel: 3B parameter models are still too small and lack strong capabilities
“So the three V models are interesting, I think, but they aren't like, they're still small and not very capable.”
Karan Goel Jun 27, 2024 ▶ 18:23 No Priors Ep. 70 | With Cartesia Co-Founders Karan Goel & Albert Gu
Opinion
Goel: Current AI speech models fail to capture profession-specific vocal nuances
“And that's sort of the nuance that I don't think any models really capture well, which is like, you know, if you're a nurse, you need to talk in a different way than if you're a lawyer, or if you're a judge, or if you're a venture capitalist, you know, very di…”

Disclosure
Goel: Cartesia intends to train an on-device multimodal model
“Yes. But, you know, we have our own sort of set of techniques that we're developing in order to be able to do that effectively. I think that I will maybe leave for another podcast. But I think, yeah, I think that is the intention at the end of the day is build…”

Disclosure
Goel: Cartesia aims to cut another 600ms of voice latency this year
“And so, you know, the roadmap is let's, let's get to the next 600 milliseconds and try to shape those off in the, over the course of the year.”

Disclosure
Goel: Cartesia aims to build edge-oriented infrastructure for SSMs
“I think in general for what we're trying to build is, is sort of the infrastructure to be able to train these models, make them run fast, and then bring them closer and closer to kind of be, you know, very edge oriented rather than cloud oriented.”

Assertion Supported
Goel: Cartesia runs Sonic TTS model locally on a standard Mac
“Yeah, I have a you know, our model running on our standard issue Mac here. Basically, this is you know, our text-to-speech model. Sonic on our playground is running in the cloud, and so you know, part of what I talked about earlier was how do you kind of bring…”
