ai engineers ship great models and awful first impressions. cache warming is the easiest, highest-leverage way to cut latency, yet almost everyone ignores it, even in voice ai. that obsession with the first second is one reason why @boardyai stands out!

interesting, yeah it’s fundamentally a different problem when you add vision. read, heard, see. as soon as humans are actually looking at something, engagement and interaction rates skyrocket

It’s a completely different problem away from cascaded/full-duplex. It’s more so context like you mention - just imagine talking to someone over the phone. You’re painting a picture in your head that could or could not be what the other person is describing. When a voice-agent in realtime can visualize things for you, you’re more engaged. That’s where I see the future of conversational ai heading towards. No longer a voice problem, a conversation problem

that's what voice ai will def turn into. I'd rather read a bunch of text then forget what the agent said 30s ago.

Last month, we had 30,000+ hours of conversation. Yes, 30 thousand. I’m the only engineer working on voice ai at @boardyai and here's what I'm noticing across the industry. In the race for faster responses and more natural voices, I think we’re losing sight of what makes a conversation actually valuable. Helping someone understand. Sometimes that takes more than words. It takes something you can see, point at, question, and explore together. That’s where I see conversational ai heading, and where I’m taking voice at Boardy.

+1 on the domain expertise especially for cascaded systems

honestly speaking most times one is enough. 2 is just a safe guard I have since prefix caching lives on one servers GPU's anyway. the only thing is that if it lands on replica 1 and the first turn routes to replica 2 it doesn't help. so when I was benchmarking this and testing just kept 2. cost is minimal anyways but yes you can easily just do 1! good q
