NVIDIA shows RLVR fine-tuning for Nemotron 3 Nano in under $5
NVIDIA Developer · youtube · 2026-07-24
NVIDIA shows how to customize Nemotron 3 Nano in Prime Intellect Lab with reinforcement learning with verifiable rewards (RLVR).
- The tutorial starts from a baseline math-python setup, trains a LoRA adapter with RLVR, deploys it, and compares results.
- The goal is to solve tool-assisted math problems within five turns.
- After 100 training steps (about 1 hour 45 minutes), the adapter completes more tasks with fewer tool calls.
- NVIDIA says the experiment costs under $5 and fixes several wrong baseline answers without regressing on previously correct ones.
