# Lab Tools & Systems > Illustrative sample content for the Lab Assistant RAG template (fictional systems). ## LitMap — graph-based literature discovery A system that helps researchers map a field rather than just rank hits. Instead of returning a ranked list like a standard search engine, LitMap is **coverage-oriented**: it builds a graph over the literature so a user can see the structure of a research area, discover related work, and navigate connections between papers and ideas. It reflects the lab's broader thesis that **graph structure is a first-class signal** for understanding and retrieval. ## ThriftRoute — cutting LLM API cost through routing + distillation A method/toolkit that reduces the number of expensive large-LLM API calls through **selective invocation** (only calling the large model when it is actually needed) combined with **online distillation** (learning from the large model's outputs so a cheaper model can handle more cases over time). This is the research basis for the **cost-aware model routing** used inside this very assistant: cheap questions are answered by a small/fast model and only substantive research questions escalate to a stronger model. ## How this assistant embodies the lab's research This lab assistant is itself a small demonstration of several of the lab's lines of work: - **Retrieval-augmented generation (RAG)** over the lab's publications — see **GraphWeave**. - **Citation-/graph-aware retrieval**: after vector search, results are expanded one hop along a paper graph (shared authors and topics), echoing **GraphWeave** and **CiteTrace**. - **Trustworthy generation**: answers are grounded in retrieved sources with inline citations, and the assistant declines to answer when the corpus does not support a claim — reflecting the lab's emphasis on robustness and uncertainty. - **Cost-aware routing**: a direct nod to **ThriftRoute**.
