Agentic RL Infra Survey: 11 Chinese Labs' Approaches to Long-Horizon Credit Assignment

This article surveys Agentic RL infrastructure across 11 leading Chinese AI labs, analyzing their architectural choices (colocated vs. disaggregated), async/partial rollout strategies, staleness control, training-inference mismatch solutions, policy optimization algorithms (GRPO, GSPO, CISPO, etc.), sparse reward credit assignment, reward hacking defenses, and environment/sandbox management, revealing six emerging paradigms and unresolved debates.
