Mooncake Optimizes Batch I/O for Miles RL: Resolving Rollout Transfer Bottlenecks in Decoupled Scaling
In large-scale reinforcement learning (RL) pipelines for foundation models, decoupled distributed architectures separate sample generation (inference/rollout) from gradient optimization (training). However, transmitting heterogeneous, fragmented rollout data—including multidimensional arrays of token sequences, loss masks, and log-probabilities—frequently creates GPU memory fragmentation and network I/O contention.
The Mooncake caching system, co-developed with LMSYS, introduced a comprehensive batch I/O optimization pipeline for the Miles RL framework. Through zero-copy memory aggregation, dynamic cross-node alignment, and asynchronous prefetch buffering, Mooncake eliminates rollout handover latency variance while preserving strict causal correctness, providing a resilient data backbone for online RL across trillion-parameter MoE architectures.

Apple Quantifies Mixed Pre-Training Scaling Laws: 2,000+ Experiments Identify Optimal Data Allocations
Domain-specialized pre-training typically requires blending scarce target-domain data with abundant general-purpose web text. Apple Machine Learning Research conducted over 2,000 systematic training runs to formalize empirical scaling laws for data-constrained mixed pre-training.
The findings map the exact inflection points governing data mixing: under-allocating domain data leaves specialized capabilities unformed, whereas excessive repetition causes steep diminishing returns and catastrophic overfitting. The resulting mathematical scaling formulas provide rigorous guidance for allocating compute and sample ratios under constrained high-quality data budgets.

Zhipu CEO Jie Tang on Post-Training Scaling Laws: "Death of Params" and the Open-Source Frontier
Tsinghua University Professor and Zhipu CEO Jie Tang joined the Latent Space podcast to review the architectural choices behind GLM-5.3, articulating insights on the "Death of Params" and post-training scaling dynamics.
Tang argued that as pre-training data scaling encounters quality ceilings, frontier model advancement is transitioning toward post-training reinforcement learning, iterative multi-agent game theory, and synthetic self-evolution. Under this paradigm, parameter count is no longer the singular bottleneck for cognitive reasoning; high activation efficiency and disciplined post-training alignment allow open architectures to achieve parity with proprietary frontier models.
