AI Researcher · Together AI
I am an AI Researcher at Together AI, where I work on large language models — post-training, reinforcement learning, and efficient inference.
I received my Ph.D. in Computer Science from Columbia University, advised by Prof. Zhou Yu, working on LLMs, dialog systems, and multimodal learning.
My research interests are broad, spanning coding agents (DeepSWE, DeepCoder, CoderForge), reinforcement learning and post-training, efficient inference, and multimodal models (LLaVA, GLIGEN). My goal is to build simple, efficient, and scalable systems for LLMs.
highlights
- XoRL — a Tinker-compatible RL system for high-performance distributed LLM training.
- CoderForge-Preview — the largest open test-verified coding agent dataset: 258K trajectories across 51K tasks.
- DeepSWE — state-of-the-art open-source coding agent trained from scratch with RL.
- DeepCoder-14B — fully open-source 14B coder model at o3-mini level.
- LLaVA: Visual Instruction Tuning — the original open-source visual instruction-tuned assistant.
- GLIGEN: Grounded Text-to-Image Generation — open-set grounded image generation with spatial control.
open-source projects
- TokenSpeed — a speed-of-light LLM inference engine designed for agentic workloads.
- TorchSpec — a torch-native framework for speculative decoding training at scale.
- Aurora — an RL framework that makes speculative decoding self-improving via a serve-to-train loop.
- XoRL — a Tinker-compatible RL system: high-performance distributed training for LLMs (RL, SFT, MoE, and beyond).
