Kimi K3 发布 47 页技术报告，最有价值的创新点是这些

TL;DR - Kimi K3 combines a 2.8T-parameter MoE architecture with infrastructure for agents that can pause, resume, and execute multi-hour tasks. Its significance lies in integrating long-context modeling, asynchronous reinforcement learning, and recoverable environments into one system.

• KDA compresses long-context state, while periodic Gated MLA layers retain access to detailed context across a 1M-token window.
• AttnRes retrieves representations from earlier depth blocks; Stable LatentMoE reduces expert communication and balances 896 experts.
• Partial rollouts prevent slow trajectories from blocking RL updates, while Firecracker microVM snapshots preserve external task state.
• The claimed 2.5× scaling efficiency reflects combined architecture, data, and training changes—not lower total cost or faster inference.
