## Open Source AI Projects

### Production RAG AI Agent
- Repository: https://github.com/SRV-YouSoRandom/ragagent
- A production-grade RAG system for PDF ingestion and context-aware conversational Q&A with full observability and streaming support.
- Two-stage retrieval: vector search (top-10) + cross-encoder reranking (top-3) for 20–30% relevance improvement
- Multi-turn conversational memory, multi-collection support, SHA256 deduplication, and LangSmith tracing
- Stack: FastAPI, LangChain, Qdrant, sentence-transformers, OpenRouter, Docker

### Recursive LLM (RLM) AI Agent
- Repository: https://github.com/SRV-YouSoRandom/rlm-agent
- An advanced agentic system where the LLM autonomously selects tools — sandboxed REPL, vector search, keyword grep, and recursive sub-LLM calls — to reason over complex long-form documents.
- Divide-and-conquer strategy: splits documents into segments with parallel sub-LLM analysis (O(log N) complexity)
- Sandboxed Python REPL via RestrictedPython; real-time streaming of agent steps and intermediate reasoning
- Stack: FastAPI, LangChain, Qdrant, OpenRouter, RestrictedPython, Docker

### RLM-LangGraph Agent
- Repository: https://github.com/SRV-YouSoRandom/rlm-langgraph
- The RLM agent rebuilt on LangGraph v1.x — replacing the black-box AgentExecutor with a fully explicit, stateful, resumable StateGraph with checkpointed memory and per-node streaming.
- Explicit StateGraph orchestration with checkpointed state: crash mid-run and resume exactly where you left off
- Same 5-tool RLM core (sandboxed REPL, recursive sub-LLMs, divide-and-conquer, vector search, keyword grep) — new LangGraph control layer
- Stack: FastAPI, LangGraph, LangChain, Qdrant, OpenRouter, Docker
