Nemotron-Terminal Model Family

Nemotron-Terminal is a family of models specialized for autonomous terminal interaction, fine-tuned from the Qwen3 (8B, 14B, and 32B). Developed by NVIDIA, these models utilize Nemotron-Terminal-Corpus, a large-scale open-source dataset for terminal tasks, to achieve performance that rivals frontier models many times their size.

Model Variants

We release the following variants of the Nemotron-Terminal family:

Nemotron-Terminal-8B
Nemotron-Terminal-14B
Nemotron-Terminal-32B

Performance on Terminal-Bench 2.0

The Nemotron-Terminal family demonstrates profound leaps in capability compared to the Qwen3 baselines across multiple specialized categories.

Model	Size	Base Accuracy	Nemotron-Terminal Accuracy
Nemotron-Terminal-8B	8B	2.47%	13.0%
Nemotron-Terminal-14B	14B	4.04%	20.2%
Nemotron-Terminal-32B	32B	3.37%	27.4%

Usage

The models are trained using the Terminus 2 scaffolding and output a structured JSON format. For evaluation on Terminal Bench 2.0, we encourage using Terminus 2 scaffolding to maintain consistency with training.

Expected Output Format

{
 "analysis": "Analysis of the current terminal state...",
 "plan": "Step-by-step plan for the next command...",
 "commands": [
 {
 "keystrokes": "ls -la\n",
 "duration": 0.1
 }
 ],
 "task_complete": false
}
