NVIDIA Nemotron 3 Nano 4B
NVIDIA's 4B efficient open model: 262K context, built for agents on modest GPUs.
About
Part of NVIDIA's 2026 Nemotron 3 family, the Nano 4B is a 4-billion-parameter open model (NVIDIA Nemotron Open Model License) optimized for agentic tool-use workflows on modest hardware, with up to 262K context. It ships with vLLM-optimized serving and the qwen3_coder parser for function calling, reflecting NVIDIA's push to own the inference stack from chip to model.
Limitations: English-only; the open license has NVIDIA-specific terms worth reading before commercial redistribution. As a 4B model it leans on tool use rather than raw knowledge — don't expect frontier recall.
