Their stored knowledge is fixed and can be wrong, and they struggle with problems that need several reasoning steps. Retrieval-Augmented Generation (RAG) addresses the first, and reasoning techniques such as Chain-of-Thought address the second. This survey argues that… 2. **[LLM-Based Human-Agent Collaboration and Interaction Systems: A Survey](https://md.research.elamur.ai/free/en/papers/zou-2026-llm-based-human-agent-collaboration/)** *(2026 · 12 citations)* Fully autonomous LLM agents remain hard to trust in practice. They hallucinate, especially across chained actions. They also falter on long, expertise-heavy tasks and raise safety, bias and accountability concerns in areas such as finance or healthcare. This survey argues for keeping people in the loop and gives what… 3. **[GAM: Hierarchical Graph-based Agentic Memory for LLM Agents](https://md.research.elamur.ai/free/en/papers/wu-2026-gam-hierarchical-graph-based-agentic/)** *(2026 · 5 citations)* LLM agents in long conversations must absorb new information without letting passing chatter corrupt what they already know. 4. **[FinReporting: An Agentic Workflow for Localized Reporting of Cross-Jurisdiction Financial Disclosure](https://md.research.elamur.ai/free/en/papers/zhang-2026-finreporting-agentic-workflow-localized-reporting/)** *(2026 · 3 citations)* Most LLM tools that extract and condense corporate financial statements are built for one market. They assume a single accounting taxonomy and filing format, which fails investors studying foreign firms. Across markets, similarly named line items can differ in meaning, equivalent concepts can carry different labels… 5. **[LightReasoner: Can Small Language Models Teach Large Language Models Reasoning?](https://md.research.elamur.ai/free/en/papers/wang-2026-lightreasoner-can-small-language-models/)** *(2026 · 1 citation)* Standard supervised fine-tuning for reasoning is expensive. It typically uses rejection sampling against ground-truth answers and then updates every token equally, even though most tokens are routine. LightReasoner addresses this by letting a weaker "Amateur" model help train a stronger "Expert" model.
