Six RAG Chunking Strategies Compared
Fixed, recursive, semantic, structural, sentence-window and parent-document chunking measured on retrieval recall across three corpora.
AI Research & Fact-Checking System
A research agent that decomposes a claim, gathers evidence from multiple sources, cross-checks agreement between them, and refuses to answer when the evidence is thin.
RAG Evaluation Lab
Most RAG systems are tuned by vibes. This is a reproducible harness that measures retrieval and generation separately, so you can see which half is failing.
RAG Evaluation System
A production-ready evaluation harness: configuration sweeps, retrieval and generation metrics measured separately, and CI regression gates.
Production AI Engineering: RAG, Agents, Evals & MCP
Retrieval that holds up, agents that fail safely, evaluation that catches regressions, and MCP for tool integration.
