About the Model
为什么要选择 Nemotron 3.5 Lightning？
Nemotron 3.5 Lightning 是 NVIDIA 于 2026 年 8 月最新发布的轻量级旗舰 MoE 模型。总参数 30B，每次仅激活 3B 参数，融合了 Mamba-2 状态空间模型与 MoE 混合架构，专为高并发 Coding Agent、工具编排与实时自动补全量身定制。
核心优势与技术突破
- 30B-A3B 极速架构：单 Token 推理延迟大幅低于传统 Dense 架构，首字生成时间达到毫秒级，大幅缩短 Agent 决策循环等待时间。
- 原生 NVFP4 深度优化：在 NVIDIA Blackwell / Hopper 架构 GPU 上深度优化，显存开销更小、吞吐速度翻倍。
- 100 万（1M）Token 上下文：支持长文本代码审阅与复杂系统日志分析，长程上下文忠实度极高。
