Over 500 developers participated in a 48-hour hackathon for Open Source Conversational & Multi-modal AI, creating innovative real-time applications such as intelligent shopping assistants and AI-powered music creators. The event was made possible by partners and sponsors including Cartesia, Google Cloud, Oracle, Coval, Pipecat, Product Hunt, Tavus, and Vapi. The winners showcased their projects in San Francisco and remotely, with the top prizes going to teams that developed an AI-powered road trip companion, a real-time voice assistant tool, and a robotic arm project combining hardware and AI for interactive demonstrations. The event demonstrated what's possible when developers combine open source tools, real-time AI, and creative vision.
