So who made this? Vercel? I know this is being posted by the Vercel CEO. Did you “commission” this as an ad? Or was it maybe built by a customer, and you helped him get visibility? What’s the story? I take it that Show HN is not just about the creation but also about the creator and the journey behind what’s being shown.

Looking at the git repo ( https://github.com/ai-ng/swift ), it was made by some web developer, not Vercel. Likely OP (Vercel CEO) just made a mistake posting it as a "Show HN".

I've been acting mostly as the 'ideas guy' and helping with the architecture / QA. It's a great way for me to dogfood Vercel and build empathy as a user in an external org, using external services.

Because the model has been trained to do what you tell it to do? That's what instruction pretraining/fine-tuning is.

Hi - I'm the developer who built this with Guillermo. We started an open source org (ai-ng) to play around with ideas that use cutting-edge AI products. I'm 16, and have only been programming for a few years, so it's a good opportunity for me to learn a lot about web development and engineering.

Congrats! I wish I would have coded like that when I was 16. Tipping my hat!

Thank you for clarifying, Guillermo.

I'm impressed by the latency using a request response. It looks this uses speech detection locally using Silero voice activity detector model using the ONNX web runtime, collects audio, then performs a POST. It doesn't look like the POST is submitted though until I'm done speaking. The response depends on chaining together several AI APIs that themselves are very, very fast to provide a seamless experience. This is v…

I totally agree, but how, though? All these architectures work with an input-output model. What we would need for what you describe would be more akin to living organisms, some sort of AI that is actually coupled to the environment (however that is defined for them) rather than receiving inputs and giving outputs. A complex, allostatic kind of multimodality than a simplistic sequential one. I don't think there is anything like that, at least not in the timescales that make sense for any use. And my belief is that the computational demands would be too high to approach with the current methods.

In autoregressive models we can "feed forward" the model by injecting additional tokens. Computing the KV cache entries for those tokens (called"prefill"), then resuming decoding. If we can do this quickly, and on the same node that has a hot KV cache (or otherwise low latency access to shared KV cache), we are quite a ways closer to offering a full duplex, or at least near zero latency, language model API. This does require a full duplex connection (i.e.: Websocket).

For true full duplex communication, including interruption, it will be more challenging but should be possible with current model architectures. The model may need to be able to emit no-op or "pause" tokens or be used as the VAD, and positional encoding of tokens might need to be replaced or augmented with time and participant.

I imagine the first language model which has "awkward pauses" is only a year or so away.

Maybe there’s something I don’t understand, but it seems to me that it would just be a streaming-next-token input instead of a batch input.
