1. Unlocking General Long Chain-of-Thought Reasoning Capabilities of Large Language Models via Representation Engineering (2025 · 19 citations)
   Reasoning models such as o1 and DeepSeek-R1 depend on long chains of thought (long CoTs) with planning, checking and backtracking. Earlier work showed this behaviour can be triggered with little data and carries over to new tasks. This paper asks whether long CoT is a general capability already present inside LLMs.
2. GroupRank: A Groupwise Paradigm for Effective and Efficient Passage Reranking with LLMs (2026)
   LLM rerankers face a trade-off between accuracy and speed. Pointwise scoring is fast but never compares documents with each other. Listwise ranking does compare them, but it exceeds context limits and relies on slow sequential sliding windows. GroupRank takes a middle path: it splits the candidate pool into small…
