That is a problem for companies that cannot send internal workflows and data to external services. The authors ask whether open-source LLMs can match closed models at turning natural-language goals into executable API calls without heavy human effort. 2. **[Agentic Context Engineering: Evolving Contexts for Self-Improving Language Models](https://md.research.elamur.ai/free/en/papers/zhang-2025-agentic-context-engineering-evolving-contexts/)** *(2025 · 39 citations)* LLM systems such as agents and domain-specific reasoners often improve by changing their input context rather than their weights. 3. **[SubgoalXL: Subgoal-based Expert Learning for Theorem Proving](https://md.research.elamur.ai/free/en/papers/zhao-2024-subgoalxl-subgoal-based-expert-learning/)** *(2024 · 10 citations)* SubgoalXL targets two obstacles for LLM-based formal theorem proving in Isabelle: proof data in this domain is scarce, and models struggle with long multi-step reasoning. ## All works 4 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1.
