Nemotron-Terminal-8B-SFT

Model Description

Qwen3-8B fine-tuned on the nemotron_terminal_filtered dataset using Supervised Fine-Tuning (SFT). This model is trained to improve terminal/coding agent capabilities, following the methodology from the paper On Data Engineering for Scaling LLM Terminal Capabilities (NVIDIA, 2026).

Final val/loss: 0.353

Training Data

Dataset: locailabs/nemotron_terminal_filtered
Description: Filtered terminal interaction data from the Nemotron corpus, containing high-quality coding and shell agent trajectories.
Split: 29,850 train / 150 val (0.5% val ratio)
