GrepSeek Trains a Search Agent to Use Shell Commands: GRPO-Trained Shell-Command Search
Researchers have developed GrepSeek, a method for training LLM agents to search text corpora using shell commands instead of traditional vector indexes. This approach trains the agent to directly interact with raw files, achieving state-of-the-art results on open-domain QA benchmarks. The training process involves a two-stage distillation with an answer-aware tutor and an answer-blind planner, followed by refinement using GRPO, and includes a parallel execution engine that accelerates search up to 7.6 times.
