Multi-Stage Assist is a highly advanced, local-first (with cloud fallback) conversational agent for Home Assistant. It orchestrates multiple processing stages to provide the speed of standard NLU with the intelligence of LLMs.
| Stage | Purpose | Technology |
|---|---|---|
| Stage 0 | Fast path - instant NLU | Home Assistant built-in |
| Stage 1 | Semantic cache lookup | Cached command replay |
| Stage 2 | Local LLM intent | Ollama (qwen3:4b-q4_K_M) |
| Stage 3 | Cloud fallback + chat | Google Gemini |
- Semantic Command Cache - Instant replay of learned commands with optimized vector lookup
