This is running in production now.

Today we at @polyaivoice are releasing Dialog-RSN-1: a dialog model that hears the call directly instead of reading a transcript of it.

Turn-taking, speech recognition, function calling and response, fused into one audio-native model. Already handling live calls.

PolyAI’s answer to speech-to-speech: Dialog-RSN-1

We trained an audio LLM to do turn taking, reasoning, response, and transcription end-to-end.

It hears you and decides when to speak, but stays efficient and controllable.

[Eddy Pei-Hao Su @peihaosu]

A good median isn't the whole story. The tail is what callers actually feel.

280ms p50 / 500ms p90, against 860ms / 1900ms for GPT Realtime.

A tight distribution, not just a good average.

@matthen2 @polyaivoice big congrats to @matthen2 and our research team on releasing this!

When something goes wrong — a power outage, a cancelled vacation, even a wildfire — the first thing people do is pick up the phone. At PolyAI, we’re the voice that answers those calls.

We just closed our Series D, surpassing $200M in total funding to make sure your critical calls never get dropped and are always handled with the care and quality of your very best human customer service reps.

Thank you to @Georgian_io, Hedosophia, @khoslaventures, @nvidia, and all of our investors for believing in our vision for the agentic enterprise.

With this funding, we’re doubling down: building agentic systems that sense, reason, and act in real time to help your business operate better and serve people when it matters most.

To those of you thinking through conversational agents for your own business, or who are working with a vendor that hasn’t stepped up as a truly transformational partner, book a demo with us. If we can’t automate 70% of your calls, we’ll donate $100k to a charity of your choice: https://t.co/ZYUhvELxl6

With our Series D, we've now raised over $200M in total funding. We're using it to make sure more of the world's top enterprises deliver legitimately helpful customer conversations. This is AI as it's meant to be. Here's the full story from CEO & Co-Founder @nikola_mrksic

[Nikola Mrkšić @nikola_mrksic]

PolyAI has raised $200M from Nvidia & multiple top VCs.

When we raised for the first time, we had no product, no revenue model, and no client.
