Bing Liu (刘冰) AI Research @ Meta Superintelligence Labs Previously, Head of Research @ Scale AI GenAI, LLM, RL, Agents San Francisco Bay Area PhD, Carnegie Mellon University Email: hadoopit [at] gmail dot com [Publications] [Work Experiences] [Education] [CV] @vbingliu My Github @hadoopit

I am an AI Research Scientist at Meta Superintelligence Labs.

Previously, I led research at Scale AI, where I focused on evaluation infrastructure, post-training data, and agentic RL for frontier models. My work includes Humanity's Last Exam, SWE-Bench Pro, and MCP Atlas, benchmarks used across leading AI labs to evaluate reasoning, coding, and agentic capabilities. I collaborated closely with frontier model developers to build scalable evaluation infrastructure and training data pipelines for long-horizon reasoning and agentic AI.

Before that, I led multilingual post-training for Llama 3 at Meta, helping scale Meta AI to over 700 million monthly active users across 40+ languages. Before that, I worked on conversational AI and AR/VR assistants at Meta Reality Labs and Google Research. I received my Ph.D. from Carnegie Mellon University and currently serve as Adjunct Professor at UC Santa Cruz, where I advise on large language models, evaluation, and agentic AI systems.
