Statements from this episode (22)
Sutin: Continuous personal context makes AI significantly more valuable
“It's clear that, like, That is the future, that personal AI, like, is just going to be very, you know, that AI is just so much more valuable with personal context.”
Sutin: Hugging Face started as a teenage chat app before Transformers
“It was a chat app for teenagers. A lot of people don't know that Hugging Face was like, Hey friend, how was school? Let's trade selfies. But then you know, they built the Transformers library, I believe to help them make their chat app better. And then they op…”
Sutin: Phone-based continuous audio fails due to mic monopolization and calls
“If you wanted to, like, have, like, continuous understanding of audio with your phone, it would monopolize your microphone, it would get interrupted by calls, and you'd have to remember to turn it on, and, like, that little bit of friction is actually, like, a…”
Sutin: Apple Watch developer frameworks restrict audio gain and sample rates
“The Apple watch you're limited in like, you don't, you can't set the gain. You can't change the sample rate. There's just a very limited framework support for doing anything with audio.”
Sutin: Smartphones will dominate until affordable smart glasses arrive in 5+ years
“We think that the phone's just so dominant and it will be until we have the next generation, which is not going to be for five, you know, maybe some Orion type glasses that are cheap enough and like light enough, like that's going to take a long time before wi…”
Sutin: Bee AI is testing a beta integration with WhatsApp
“So, you know, one integration we have that is in beta is with WhatsApp.”
Sutin: Bee executes agent actions using cloud-hosted Android phones
“Is an Android cloud phone. So it's going to be able to, you know, that has access to all my accounts. So we're going to abstract this away in the execution environments, not really important, but like we can go into technically why Android is actually a pretty…”
Wang: ChatGPT cannot match hardware agents without an always-on recording layer
“Just being able to have wake words, like enables some form of sort of voice agent, agent features that even chat GPT can never have because they don't have the recording layer.”
Wang: Wearable competitors Friend AI and Limitless AI lack developer APIs
“Real friend doesn't have an API and then limitless also doesn't have an API.”
Sutin: Social norms will adapt to ambient AI hardware within five years
“People's behaviors and expectations will change, whether that's like, you know, something that is going to happen now or in five years, it's probably in that range.”
Sutin: Bee deletes raw audio and focuses its summaries on the user
“We process the audio. And nothing has persisted, and then it's summarized with the speaker identification focusing on the user.”
Sutin: Bee is adding geofencing and 'concept fencing' to control recording
“So we're adding certain features like geofencing, just like at this location, it's just never active and even like concept fencing. So you can be like, if these topics come up, then like don't, no capturing of that.”
Sutin: Bee ships over 100 wearables daily, with Texas leading orders
“We have out there are daily shipment of like over a hundred. If you go look at the addresses, like Texas, I think is our biggest state and Florida, like just the biggest states”
Sutin: Bee intentionally avoided an over-hyped Rabbit-style CES launch
“We didn't want to do like a big over hypey promised kind of rabbit launch. Cause I mean, they did hats off to them, like on the presentation and everything, obviously, but like, you know, we want to let the product kind of speak for itself and like, get it out…”
Sutin: Hardware startups get immense value at CES without buying booths
“I think to do it like a big rabbit style or to have a huge show on there, like you need to plan that six months in advance. And it's very expensive, but like, if you know, go there, there's everybody's there, all the media is there. There's a lot of some pre-s…”
Sutin: The Humane AI Pin failed due to weight and overheating
“I think the Humane is like pretty incredible. Some of the engineering they did, but like, it wasn't kind of geared towards solving the problem. It was just it's too heavy. The swappable batteries is too much demand. The heat, the thermals is like too much.”
Sutin: Continuous wearable video requires impractically large batteries for radio transmission
“The radio is actually the thing that takes up the majority of the power, so you would really have to have quite a, like, an unacceptably, like, large and heavy battery to do it continuously all day.”
Sutin: Bee leveraged Los Angeles defense suppliers for quick PCB prototyping
“So we got our first There's PCB and the assembly done in LA. So there's a lot of good because of the defense industry that can do quick churn.”
Sutin: Traditional speech-to-text ASR will soon be obsolete and uninvestable
“Cause it's very clear that like all ASR, all speech to text is going to be pretty obsolete pretty soon. So like investing into that is probably kind of a dead end cause it's just going to be obsolete.”
Sutin: Existing general RAG frameworks will likely become obsolete
“I think existing kind of rag pipelines also will probably be obsoleted. The frameworks, I have not found one, like, there's no general Way to do RAG that works like it's really highly dependent on the data.”
Sutin: Bee replaced traditional RAG embeddings with massively parallel small models
“What we've learned is, like, doing the traditional, like, embedding and RAG is suboptimal. We kind of built our own using small models to do really massively parallel retrieval, which I think is going to be maybe more common in the future.”
Sutin: LLMs struggle to effectively process knowledge graphs at inference time
“The problem with knowledge graphs that we found is like, and I don't know if you can tell me what your experience has been, but they're great for representing the data, but then like using it at inference time is kind of challenging, like... Just like the LLM …”
