Needle 3 智能阶梯：一套权重从 2 到 20 层任意深度皆可部署
Intelligence Ladders: One Set of Weights, Every Depth a ModelNeedle 3 is trained so that any depth from 2 to 20 layers is a deployable model. This is how the subnetworks are chosen, how they are trained without training five models, and what each one scores.Henry Ndubuaku · September 17, 2026 · 12 min read
导读
Needle 3 训练为任意 2-20 层深度都是可部署模型，共享同一残差流，按设备内存预算选择深度而无需为每个尺寸单独训练；文中解释子网络选择、免多轮训练的方法及各深度得分。
推荐理由
一套权重覆盖多种端侧内存预算的工程思路，可跟踪性强。
