Nemotron Lightning 3.5 30B A3B carries NVIDIA's full checkpoint name for the Lightning release of August 11, 2026, where A3B denotes the roughly 3 billion parameters that activate out of a 30 billion parameter Mixture-of-Experts. Interleaved Mamba-2 and MoE layers, with attention used sparingly, are what let it serve at small-model speed. NVIDIA publishes it under OpenMDW-1.1 with the training data and recipes alongside the weights, so it can be modified and deployed commercially without a fee, and it is distributed in BF16 and NVFP4 builds for different accelerator budgets. It is built for the high-frequency, tool-heavy steps of an agent loop, the kind of work where per-call latency matters more than raw capability.
