- **Model Architecture:** NemotronHForCausalLM - **Input:** Text - **Output:** Text - **Model Optimizations:** - **Weight quantization:** FP8 - **Activation quantization:** FP8 - **Release Date:** 2026-08-13 - **Version:** 1.0 - **Model Developers:** RedHatAI This model is a quantized version of nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16. This model was obtained by quantizing the weights and activations of nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16 to the FP8 data type, using a per-tensor static scheme. This reduces the number of bits per parameter from 16 to 8, cutting GPU memory and disk requirements by approximately 50% and roughly doubling matrix-multiply compute throughput on FP8-capable hardware. Only the weights and activations of the linear operators within the transformer blocks are quantized, using LLM Compressor.

Frequently asked questions

Do open weights permit free commercial use?

Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.

Are these real-time billing prices?

These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
