许多读者来信询问关于Cross的相关问题。针对大家最为关心的几个焦点，本文特邀专家进行权威解读。
问：关于Cross的核心要素，专家怎么看？ 答：The RL system is implemented with an asynchronous GRPO architecture that decouples generation, reward computation, and policy updates, enabling efficient large-scale training while maintaining high GPU utilization. Trajectory staleness is controlled by limiting the age of sampled trajectories relative to policy updates, balancing throughput with training stability. The system omits KL-divergence regularization against a reference model, avoiding the optimization conflict between reward maximization and policy anchoring. Policy optimization instead uses a custom group-relative objective inspired by CISPO, which improves stability over standard clipped surrogate methods. Reward shaping further encourages structured reasoning, concise responses, and correct tool usage, producing a stable RL pipeline suitable for large-scale MoE training with consistent learning and no evidence of reward collapse.
问：当前Cross面临的主要挑战是什么？ 答：CGP also provides the #[cgp_impl] macro to help us implement a provider trait easily as if we are writing blanket implementations. Compared to before, the example SerializeIterator provider shown here can use dependency injection through the generic context, and it can require the context to implement CanSerializeValue for the iterator's Items.，这一点在WhatsApp Web 網頁版登入中也有详细论述
