What is Nemotron-4 15B?
Nemotron-4 15B is an open-source large language model developed by NVIDIA, released in February 2024 as part of NVIDIA's growing open AI portfolio. With 15 billion parameters and a training corpus of 8 trillion tokens covering 50+ natural languages and 43 programming languages, it strikes a balance between size, multilingual capability, and inference efficiency.
Released under the NVIDIA Open Model License, it's free for commercial use with standard responsible-use restrictions.
Why Nemotron-4 Is Trending in 2026
NVIDIA has aggressively expanded the Nemotron family — adding Nemotron-4 340B (a synthetic-data generation powerhouse) and Llama-3.1-Nemotron-70B-Instruct (which briefly topped Arena leaderboards). This makes Nemotron one of the most strategically important open-model lines in 2026.
Nemotron-4 15B is specifically optimized for NVIDIA TensorRT-LLM and Triton Inference Server, delivering exceptional throughput on NVIDIA hardware.
Key Features and Capabilities
Nemotron-4 15B supports 53 languages, 43 programming languages, function calling, structured output, and a 4K-token context window. The newer Llama-3.1-Nemotron variants extend this to 128K context.
Who Should Use Nemotron-4?
Nemotron-4 is built for enterprises with NVIDIA GPU infrastructure, NIM customers, multilingual product teams, and developers needing TensorRT-LLM-optimized models.
Top Use Cases
Real-world applications include multilingual customer support, code generation, RAG systems, synthetic training data generation, function-calling agents, and high-throughput batch inference on NVIDIA GPUs.
Where Can You Run It?
Nemotron-4 runs on NVIDIA NIM, Hugging Face Transformers, vLLM, TensorRT-LLM, and Triton Inference Server. The 15B model fits in 32 GB VRAM at full precision; H100 and A100 GPUs deliver excellent throughput.
How to Use Nemotron-4 (Quick Start)
Easiest: deploy via NVIDIA NIM or use the build.nvidia.com hosted endpoint. For Hugging Face: nvidia/nemotron-4-15b. For maximum performance, convert to TensorRT-LLM format.
When Should You Choose Nemotron-4?
Choose Nemotron-4 when you have NVIDIA GPU infrastructure and need multilingual or code-focused inference at high throughput. For general use, Llama 3.1-8B may have a larger ecosystem.
Pricing
Nemotron-4 is free under NVIDIA Open Model License. NVIDIA NIM hosting has tiered pricing for enterprises.
