NASA SE Handbook Preview

Developed by: MarshallDoyle
Fine-tuned from: unsloth/meta-llama-3.1-8b-instruct-unsloth-bnb-4bit
Specialization: NASA Systems Engineering Handbook (2018) Q&A
Training recipe: LoRA rank=16, epochs=3, steps=285, final loss≈0.40–0.60


✨ Key Features

Feature Details
Domain Expertise Deep knowledge of NASA SE lifecycle, terminology, and best practices.
Compact Footprint +83.8M trainable via LoRA on 8B base.
Long Context Up to 128K token support for large documents.
Fast Inference Efficient TRL & Unsloth pipeline.

🎯 Intended Use Cases

  • Interactive Q&A: Rapid lookup of definitions, processes, and phase purposes.
  • Summarization: Concise overviews of complex sections in the handbook.
  • Educational Tools: Training aids for systems engineering students and professionals.
  • Mission Planning: Quick reference for verification, validation, and lifecycle checkpoints.

📊 Example Comparisons

Phase C Purpose
Model Response Snippet
Base LLaMA-3.1 “Phase C covers detailed design and preparations for manufacturing…” (generic)
Fine-Tuned “The main purpose is to complete the detailed design of system elements, fabricate hardware, and code software, ensuring all end products are defined for integration.”
Verification vs. Validation
Model Response Snippet
Base LLaMA-3.1 “Verification checks requirements; validation checks user needs…” (too brief)
Fine-Tuned “Verification ensures the system meets specified requirements; validation confirms it satisfies stakeholder expectations in its intended environment.”

⚠️ Limitations

  • Scope Bounded: Content based on the 2018 handbook; may omit newer updates.
  • Hallucinations: Possible on out-of-handbook queries.
  • Bias: NASA-specific terminology; verify critical engineering decisions against official documents.
