README

NVIDIA Nemotron 3.5 Bolt 74B-A9B 24GB

Vision-language reasoning model from NVIDIA, compressed from Nemotron 3.5 Super VL for local use on RTX GPUs. Contains 74B total parameters with only 9B active at a time, using a hybrid Mamba-2, Mixture-of-Experts and Attention architecture with a C-RADIO v4-H vision encoder. NVIDIA provides it in 2-bit (IQ2) form, so the full model fits in about 24 GB.

Accepts image and text input. Features a reasoning toggle to enable or disable intermediate reasoning traces, and an optional medium reasoning effort mode. Includes native agentic capabilities for tool use and structured output.

Supports a context length of 256K tokens.
