It's deployed at api.synapse.elia.vc.

Claude + AI usage (backend):

• Topic extraction: Anthropic Claude (Haiku) via Messages API, returning normalized topics + confidence
• Agentic reasoning: Claude (Sonnet) ranks experts (score × freshness) and powers the matchmaker orchestration
• Embeddings: OpenAI embeddings API; semantic chunking improves recall; vectors stored in pgvector

Claude + AI usage (frontend):

• Chat: Sonnet-3.5 via Openrouter & local tool-calls
• Voice: Elevenlabs (TTS & STT - LLM: Sonnet-3.5)
• Video: BeyondPresence
