NVIDIA · 2026-08-11
NVIDIA's BF16 reference release of Nemotron 3.5 Lightning, a hybrid Mamba-2, attention and mixture-of-experts language model with optional thinking. The official card documents a 1,048,576-token maximum context and an August 11 release. Fireworks explicitly links its nemotron-lightning-3p5-30b-a3b endpoint to this checkpoint; those identified runs remain separate from NVFP4 and precision-unspecified observations. Rounded parameter figures are not treated as exact checkpoint counts.
