Boston Aerospace AI v1.0.0 โ€“ Official Launch
I'm a self-taught 19-year-old developer from Chimoio, Mozambique, and I built Boston Aerospace AI entirely on my own. This is its first stable release: an OpenAI-powered intelligence layer for aerospace predictive maintenance.

The Origin Story
I didn't come into this from inside the aerospace industry โ€” I came into it from the opposite direction. My first "lab" was a dumping site behind repair workshops in Chimoio. My first sensor was salvaged from a broken DVD drive. I taught myself machine learning through PDFs downloaded whenever I had internet access, coding in Termux between power outages.
The idea behind Boston Aerospace AI came from a simple observation: predictive models can tell you a component's Remaining Useful Life with real accuracy, but they can't tell you why it's degrading or what to investigate next. SHAP helps โ€” but raw feature-importance numbers still aren't an answer an engineer can act on.
So I set out to build a system that doesn't replace predictive models, but wraps them in something that can actually explain and investigate.

The Problem We're Solving
Black-Box Predictions โ€” ML models output RUL estimates and anomaly scores, but not the "why."
Information Silos โ€” sensor data, technical manuals, and external research live in disconnected places.
Time Pressure โ€” in aerospace, every hour spent manually investigating an alert is an hour not spent preventing failure.

How Boston Aerospace AI Addresses This
Foundation: Trusted ML Models
The core is a 6-model ML ensemble (XGBoost, LightGBM, CatBoost, Random Forest, GBR, Extra Trees) trained on NASA's CMAPSS turbofan dataset to estimate Remaining Useful Life.
Transparency: SHAP Explainability
Every prediction comes with SHAP analysis showing exactly which sensor signals drove it.
Intelligence: OpenAI Orchestrator
This is the new piece in v1.0.0. The orchestrator takes the ML prediction and SHAP explanation and enriches them with:
Internal technical documentation (manuals, service bulletins) โ€” when available.
External web research โ€” when the question needs it (the model decides per-query, not on every message).
It synthesizes all of this into a structured answer to three questions: What is happening? Why is it happening? What should I investigate?

Source-Aware Analysis
Every part of the answer is tagged by origin โ€” ๐ŸŸข ML Prediction, ๐ŸŸก SHAP Explanation, ๐Ÿ”ต Internal Document, ๐Ÿ”ด External Research โ€” computed by the system itself, not self-reported by the model, so the attribution is reliable.

From Prototype to Platform
Phase 1 โ€” Local prototype. I originally built the assistant on Ollama, running fully offline/locally โ€” important given inconsistent connectivity where I live.
Phase 2 โ€” OpenAI integration (this release). I rebuilt the orchestration layer on OpenAI's Responses API with native web search and structured output, which meaningfully expanded reasoning depth and made source-aware synthesis possible. The Ollama/local path stays in the codebase as a future option for operators who need fully offline, air-gapped deployments.

Important Disclaimer
Boston Aerospace AI is a research and decision-support prototype. It is not certified for autonomous maintenance decisions and must never replace qualified aerospace engineers, approved maintenance procedures, or regulatory requirements (FAA, EASA, etc.). It's a collaborative assistant that helps engineers investigate faster โ€” the final decision always rests with a human engineer.

Technical Architecture

โœ… Computer vision modules (crack detection, thermal analysis, vibration anomaly)
โœ… Automated PDF maintenance reports

We Need Your Feedback
This is a solo, self-funded project, still early. If you try it, break it, or have ideas for what would make it genuinely useful to real maintenance teams, I want to hear it โ€” that feedback is how this gets better.

What's Next
Validation with real (non-synthetic) operational data
Integration with additional data sources (fleet history, weather, supply chain)
Custom fine-tuning for specific engine types
Working toward compliance/certification readiness
Built alone, from Mozambique, with more curiosity than resources. Thanks for checking it out. ๐Ÿ›ฉ๏ธ

What could you build with GPT-5.6 that wasnโ€™t practical before?
Before GPT-5.6, my AI assistant was a simple Q&A chatbot bolted onto the ML predictions โ€” it could summarize a manual or answer a basic question, but couldn't investigate anything. GPT-5.6's native web search tool changed the scope of what I even tried to build: instead of a chatbot, I built an orchestrator combining ML predictions, SHAP explainability, internal documents, and live web research into one structured, source-attributed analysis โ€” deciding per question whether external research is even needed, rather than forcing every query through the same shallow path. Structured output also let me move from free-text answers to a reliable JSON schema (risk, evidence, sources, recommended investigation) a dashboard can render deterministically. That's the difference between a demo chatbot and something an engineer could plausibly trust during a real investigation. GPT-5.6 made a genuinely new architecture worth building, on a timeline a solo, unfunded developer could actually ship.
