I forgot that we're playing the demo games now.

Well I'll see your demo, and raise you another demo

Except that demo was done by a single person, with a day job and no cap table.

Love to see people has interest over our demo. But, I checked his former post, and he already built a voice Agent a couple of days ago. So I believe he just changed the prompts to create this demo: https://twitter.com/sean_moriarity/status/175895035375034804.... Also, after testing their live demo at https://nero.ngrok.dev/, it appears it might still be missing some key features, such as latency and endpoint detection.

As a bystander, I definitely agree that Retell's demo wins on latency — it felt pretty close to human. The voice also sounds more natural to my ears (not sure why, since Nero is apparently using Eleven Labs for voices, and Eleven's voices usually sound pretty good to me).

Playing around with the Nero demo, it also feels pretty... broken? I never actually managed to make a booking with Nero; it seemed to often not be able to tell I was done speaking, and would just hang after a couple back-and-forths. Still impressive for a one-man demo built quickly, but they don't feel in the same league.

I do wish Retell's pricing was cheaper, though; $6/hr is pretty much the cost of a call center employee in India, and LLMs still perform below the average human on most things. That being said, I imagine the cost of Retell will come down as the tech advances, and LLMs will also improve over time.
