QeRL: Revolutionizing LLM RL Training on a Single H100—Quantization That Sparks Exploration and Crushes Costs

8 hours ago 高效码农

Picture this: You’re knee-deep in debugging an RL pipeline for a 32B LLM, your H100 GPU’s fans screaming like a jet engine, and yet another out-of-memory error crashes your session. Rollouts drag on for hours, rewards barely budge, and your electricity bill rivals a small country’s GDP. Sound familiar? As an AI dev, I’ve been there—staring at frozen progress bars, wondering if true reasoning in large language models is just a pipe dream. But what if I told you there’s an open-source framework that tames this beast on one H100, slashes training time by up to 2x, and—get this—turns quantization …
