  • Backend: FastAPI ASGI server utilizing bidirectional WebSockets for high-frequency duplex streaming of raw audio packets and system configs.
  • AI Models (STT & Multi-LLM): Powered by Groq API — Whisper-large-v3-turbo for rapid Speech-to-Text and a Multi-Model LLM Routing Layer selecting Qwen3.6 27B (qwen/qwen3.6-27b — active primary model) with fallback to openai/gpt-oss-120b (complex reasoning) and Llama-3.1-8b-instant (ultra-low latency) for agent reasoning, timezone-aware localized queries, and function-calling routing.
