Latest News
Arbor learns from its own runs by retaining reusable findings and recalling them for similar tasks.
Arbor adds built-in literature search and idea-novelty checks through the public alphaXiv API.
VentureBeat reports that Arbor beats Claude Code and Codex by 2.5x on the same compute budget in the reported evaluation.
Arbor's native CLI runtime and Agent Skill Suite for Codex and Claude Code are released.
Products & Services
Open-source autonomous research/optimization agent. A long-lived coordinator maintains a persistent hypothesis tree while short-lived executors run experiments in isolated Git worktrees; verified improvements are promoted only after held-out evaluation.
Open-source research toolkit for retrieval-augmented generation listed in the RUC-NLPIR GitHub organization.
Research project for giving large reasoning models deep-research capabilities through an agentic search framework.
Research system for real-world financial deep research.
Market Position
RUC-NLPIR positions itself as an academic IR/NLP lab rather than a commercial vendor. Its Arbor project differentiates from general-purpose coding agents such as Claude Code and Codex through persistent hypothesis-tree memory, parallel isolated experiments and held-out-test promotion; VentureBeat reported Arbor achieved over 2.5x their average relative held-out gain in the reported evaluation. Its broader research projects overlap with open-source RAG, agentic-search and deep-research ecosystems.
