Key Technical Takeaways

1. Massive Quality Jump (+269.0% F1 Gain):
   • Fine-tuning Qwen2.5-72B-Instruct via 4-bit QLoRA elevated the mean token F1 score from 0.1393 to 0.5140 across 100 frozen holdout AIOps incident prompts (aiops_mix_test_100.jsonl).
2. Dominant Win Rate (88 / 100 Prompts):
   • Improved accuracy and gold-standard label alignment on 88 out of 100 test prompts.
3. Style Shift from Textbook Chatter to Operational Triage:
   • Transformed long-winded 1,072-character tutorial responses into exact 466-character incident root-cause and remediation summaries.
4. Hardware & VRAM Efficiency:
   • Single-epoch QLoRA fine-tuning completed in 134.15 minutes (2.23 hours) on 2× H200 GPUs, using only 20.22 GB (GPU 0) / 32.49 GB (GPU 1) peak VRAM.
