The haus²⁵ autonomous curation system represents the first fully operational multi-agent representation agency for live performers. Built using LangChainJS modules and LangGraphJS patterns, it provides AI-powered event optimization from planning to promotion to post-production.

​
Architecture Overview

The curation system implements a hierarchical multi-agent architecture where specialized agents are coordinated by supervisor agents across three distinct scopes.

​
Core Innovations

​
1. LangChainJS Module Integration

The system leverages multiple LangChainJS modules for cost-efficient operations: Embedding and Vector Storage: GoogleGenerativeAIEmbeddings with MemoryVectorStore for user history indexing and contextual retrieval. Summarization Chains: TokenTextSplitter combined with LoadSummarizationChain using “refine” type for cost reduction on large social media datasets. Multi-Model Orchestration:
  • Gemini 2.5 Flash Lite: Creative tasks (titles, descriptions)
  • Gemini 2.0 Flash Exp: Analytical tasks (pricing, scheduling)
  • Claude 3.5 Sonnet: High-quality content strategy
  • GPT-4o-mini: Specific platform optimizations

​
2. On-Chain Iteration System

Unlike traditional agentic frameworks that use expensive vector databases or inconsistent local storage, haus²⁵ implements the first on-chain iteration system for AI memory and RAG operations. Technical Advantages:
  • 100x cost reduction compared to traditional vector storage
  • Immutable single source of truth prevents cache inconsistencies
  • Persistent across deployments eliminates data loss risks
  • Transparent audit trail for all AI decisions
Implementation Pattern: Each iteration contains aspect type, iteration number, original/proposed values, AI rationale, confidence score, timestamp, and source. Storage flows through EventManager contract updates with Pinata IPFS metadata uploads.

​
3. Supervisor Orchestration Pattern

Based on LangGraphJS StateGraph patterns but simplified for production efficiency. PlannerSupervisor coordinates agents through two-phase execution: shared context preparation (user history indexing, category research) followed by parallel specialized agent execution (title, description, pricing, schedule, banner generation).
