Hi HN! Last year the project I launched here got a lot of good feedback on creating speech to speech AI on the ESP32. Recently I revamped the whole stack, iterated on that feedback and made our project fully open-source—all of the client, hardware, firmware code. This Github repo turns an ESP32-S3 into a realtime AI speech companion using the OpenAI Realtime API, Arduino WebSockets, Deno Edge Functions, and a full-stack web interface. You can talk to your own custom AI character, and it responds instantly. I couldn't find a resource that helped set up a reliable, secure websocket (WSS) AI…

Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to…

Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.…

Henry, Matt and James here – we’re building an open source toolkit that makes it easy to integrate an LLM-powered copilot that talks to your API into software products. It works by calling API endpoints which you choose to expose to it. This lets the chatbot complete tasks within your software in response to natural language queries. It’s also open source, so you don’t have to send user data to another 3rd party. We support Llama 2, but we haven’t fine-tuned Llama 2 yet (coming soon) so highest accuracy is seen with GPT-4 or fine-tuned GPT-3.5 (much faster). We started working together 2…
