Expert-built sets are expensive: GPQA's 500 questions reportedly cost over $120,000. Live human evaluation such as Chatbot Arena is too slow for developers to use routinely. The authors present BenchBuilder, an… 2. **[RouteLLM: Learning to Route LLMs with Preference Data](https://md.research.elamur.ai/free/en/papers/ong-2024-routellm-learning-route-llms-preference/)** *(2024 · 109 citations)* Deploying LLMs forces a trade-off: frontier models such as GPT-4 give the best answers but are costly, while cheaper models like Mixtral-8x7B struggle with harder requests. 3. **[Meta-Rewarding Language Models: Self-Improving Alignment with LLM-as-a-Meta-Judge](https://md.research.elamur.ai/free/en/papers/wu-2025-meta-rewarding-language-models-self/)** *(2025 · 64 citations)* Self-Rewarding training lets an LLM improve without human labels by scoring its own outputs. However, it trains only the model's answering skill. Its evaluation skill stays fixed, so gains plateau after a few iterations and the model risks reward hacking. The authors add a third role, a meta-judge, alongside the… 4. **[TopoRAG: Graph-based RAG via Topology-aware Approximate Nearest Neighbor Search](https://md.research.elamur.ai/free/en/papers/wu-2026-toporag-graph-based-rag-topology/)** *(2026)* Graph-based RAG systems like GraphRAG and LightRAG usually find evidence in two steps. A plain vector ANN lookup first picks the top-k entities. Their graph neighbours are then added by heuristic expansion. Because the graph is ignored in the first step, the expansion tends to pull in weakly related entities and… ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Ion Gabriel Stoica](https://md.research.elamur.ai/free/en/authors/ion-gabriel-stoica/) ×2 - [Joseph E.
