Title: ResearchGPT: Benchmarking and Training LLMs for End-to-End Computer Science Research Workflows
Primary area: datasets and benchmarks
Keywords: Benchmark, LLM

Abstract: As large language models (LLMs) advance, the ultimate vision for their role in science is emerging: we could build an AI collaborator to effectively assist human beings throughout the entire scientific research process. We refer to this envisioned system as *ResearchGPT*.  Given that scientific research progresses through multiple interdependent phases, achieving this vision requires rigorous benchmarks that evaluate the *end-to-end* workflow rather than isolated sub-tasks. To this end, we contribute **CS-54k**, a high-quality corpus of scientific Q&A pairs in computer science, built from 14k CC-licensed papers. It is constructed through a scalable, paper-grounded pipeline that combines retrieval-augmented generation (RAG) with multi-stage quality control to ensure factual grounding. From this unified corpus, we derive two complementary subsets: **CS-4k**, a carefully curated benchmark for evaluating AI’s ability to assist scientific research, and **CS-50k**, a large-scale training dataset. Extensive experiments demonstrate that CS-4k stratifies state-of-the-art LLMs into distinct capability tiers.  Open models trained on CS-50k with supervised training and reinforcement learning demonstrate substantial improvements. Even 7B-scale models, when properly trained, outperform many larger proprietary systems, such as `GPT-4.1`, `GPT-4o`, and `Gemini 2.5 Pro`. This indicates that making AI models better research assistants relies more on domain-aligned training with high-quality data than on pretraining scale or general benchmark performance. We release CS-4k and CS-50k in the hope of fostering AI systems as reliable collaborators in CS research.
