If you want to dig deeper on the architecture, I wrote up the dual-LLM design and the memory system on my engineering blog:
- https://www.conecrows.com/blog/augur-soft-launch — covers the dual-LLM turn loop, perception gating, and why the single-LLM approach failed - https://www.conecrows.com/blog/augur-memory-v1 — covers impression extraction, vector embeddings, and lossy synthesis
The stack is Fastify, Next.js, Supabase (Postgres + Auth), and both OpenAI and Anthropic models for the engine and analysis. Encounters cost roughly $0.08–$0.15 per turn (internal cost) depending on state complexity and encounter length.
