LLM orchestration and evaluation platform with grounded retrieval

An AI engineering system for orchestrating, evaluating, and comparing LLM reasoning paths with LangGraph/LangChain, provenance tracking, retrieval, and measurable cost/quality tradeoffs.

01 / Problem

Scientific LLM systems can produce confident reasoning without making retrieval, evidence use, uncertainty, and citation integrity independently inspectable.

02 / System
01

Grounds claims in live scientific retrieval through Biolab MCP and stores provenance for each step.

02

Supports a single-call default path plus an explicit Advocate-Skeptic-Synthesizer evaluation path.

03

Rejects citations that are not present in retrieved evidence instead of silently accepting them.

04

Includes a real evaluation harness comparing the multi-agent design against a single-call baseline.

03 / Proof

On the current 10-claim evaluation, the debate pipeline underperformed the single-call baseline on every measured metric while costing about 7.4x more; the system was changed to default to the measured-better path instead of hiding the negative result.
