Building a Real-Time AI System for Baseball Training: What Broke and What Worked

Attack Tee was not a “computer vision app.”
It was a real-time training system operating under tight latency and reliability constraints.

Key challenges we faced:

  • Sub-second feedback requirements
  • High-speed motion blur
  • Inconsistent lighting and hardware noise
  • Coach-facing interpretability

Architecture decisions that mattered:

  • Edge-first processing to reduce latency
  • Conservative model thresholds to avoid false confidence
  • Explicit fallbacks when confidence dropped
  • Feedback timing designed around athlete perception, not frame accuracy

Biggest lesson:
Production AI is a systems problem. Models are only one component.
Most failures we see today happen because teams treat AI as a plug-in

instead of an operational system.
If you’re designing AI for real-world interaction, optimize for:

  • Consistency
  • Latency
  • Trust

Not leaderboard metrics.
