RLHF: PPO vs GRPO vs GSPO
5/5Dive into advanced reinforcement learning concepts by comparing prominent alignment techniques such as PPO, GRPO, and GSPO, based on applied scientist interviews at Amazon. This deep-dive examines the mathematical formulations behind clipped surrogate objectives, KL divergence penalties, group-based relative advantages, and how recent reasoning-focused models leverage these updates. You will also analyze reward model construction, mitigation strategies for reward hacking, and distributed training topologies. The complete analytical breakdown and model response guide require a subscription.

4/5A conceptual question on modern methods for aligning language models with feedback. It checks whether you can state each training objective exactly, explain what data and auxiliary models each one requires, and choose sensibly between them for preference data, verifiable tasks and control problems.
