GitHub Trending: Open-Source Modern RL Curriculum from Basics to LLM Alignment & Agents
udmrzn · x · 2026-08-09
The open-source project Hands-On Modern RL offers a comprehensive, practice-first curriculum bridging classic control to LLM post-training.
- Complete Roadmap: Starts with classic algorithms like CartPole, DQN, and PPO, advancing to RLHF, DPO, GRPO, RLVR, and extending to Agentic RL, tool calling, multi-turn credit assignment, and VLM RL.
- Practice-First: Features runnable code, training curves, and failure case studies (e.g., implementing PPO from scratch, math reasoning GRPO, Mini Deep Research Agent). It also tackles practical engineering issues like training collapse, reward hacking, and KL drift.
- Frontier Focus: Expands training objects from single-turn answers to full trajectories, discussing asynchronous rollouts and core topics needed for agents to transition from 'answering' to 'long-term acting'.
The authors note the project is still iterating rapidly with some AI-assisted content pending full review, recommending cross-verification with original papers and code.
