Most earlier work trains them with supervised fine-tuning on expert trajectories. That approach treats tool use as plain text generation and ignores that it is a sequence of decisions. StepTool instead casts tool learning as a… 2. **[Knowledge-to-Verification: Exploring RLVR for LLMs in Knowledge-Intensive Domains](https://md.research.elamur.ai/free/en/papers/yuan-2026-knowledge-verification-exploring-rlvr-llms/)** *(2026)* RLVR has improved LLM reasoning mainly in math and code, where answers can be checked automatically. Fields such as agriculture, law and medicine lack such checkable data, and answer-only rewards are sparse and tolerate flawed reasoning. The authors propose K2V (Knowledge-to-Verification) to address both gaps.
