Live demos show an Android app using Onnx Runtime for on-device inference (a 12 MB object detector that misses some statues) and a local build of Whisper (about 57 MB) plus cloud fallbacks to OpenAI GPT-3.5 for summarization and chat. A simple text editor sends HTML to OpenAI and returns nondeterministic summaries; a JetChat client uses GPT with a mutable conversation buffer. Conference schedule is embedded as 1,500‑dim vectors and matched by dot‑product with a 0.8 cutoff to ground answers, and hybrid local/cloud fallback logic is implemented and functional.
