We introduce Ling 2.0, a series reasoning-oriented language foundation built
upon the principle that every activation boosts reasoning capability. Designed
to scale from tens of billions to one trillion parameters under a unified
Mixture-of-Experts (MoE) paradigm, Ling 2.0 emphasizes high sparsity,
cross-scale consistency, and efficiency guided by empirical scaling laws. The
series includes three non-thinking (instruct) models - Ling-mini-2.0,
Ling-flash-2.0, and Ling-1T - ranging from 16B to 1T total parameters and
achieving up to 7-fold active-compute efficiency compared with dense
counterparts. Ling 2.0 integrates coordinated innovations across model
architecture, pre-training, post-training, and infrastructure: a high-sparsity
MoE with MTP for efficient reasoning, reasoning-oriented data and mid-training
CoT activation, reinforcement-based fine-tuning (DFT, Evo-CoT), and full-scale
FP8 training with fine-grained heterogeneous pipelines. At the trillion scale,
Ling-1T establishes a new Pareto frontier of reasoning accuracy versus
computational efficiency, demonstrating that sparse activation, when properly
aligned with reasoning objectives, enables scalable and efficient intelligence.
Collectively, Ling 2.0 provides a coherent, open, and efficient foundation for
advancing future reasoning and thinking models, including the Ring series built
upon the same base.
