Qwen3.5-0.8B — System Command Intent Parser

Fine-tuned from Qwen/Qwen3.5-0.8B using QLoRA on a custom dataset of system monitoring inputs mapped to structured JSON action plans.

Given a natural language system alert, the model outputs a structured JSON describing the intent, required actions, risk level, and confidence score.


Example

Input

RAM at 95%, system becoming unresponsive

Output

{
  "intent": "memory_check",
  "steps": [
    {"action": "check_memory", "params": {}},
    {"action": "list_processes", "params": {"sort": "memory", "limit": 10}}
  ],
  "risk": "medium",
  "confidence": 0.88
}

Output Schema

Field Type Description
intent string Classified action category (e.g. memory_check, disk_cleanup, cpu_check)
steps array Ordered list of actions with optional parameters
risk string low / medium / high
confidence float Model confidence 0–1

Prompt Format

The model uses Qwen3.5's native ChatML format:

<|im_start|>system
You are a structured data extractor. Given an input, output a valid JSON object and nothing else.<|im_end|>
<|im_start|>user
{your system alert here}<|im_end|>
<|im_start|>assistant

Limitations

  • Trained on a system-monitoring domain — may not generalise to unrelated tasks
  • Small model (0.8B) — complex multi-step plans may occasionally be incomplete
  • Risk and confidence values reflect training data distribution; treat as heuristic
  • Dataset size (374 examples) is small — broader coverage would improve robustness
