Evaluating LLMs' Effectiveness on Real-World Consumer Device Repair Questions

arXiv:2606.03331v1 Announce Type: new Abstract: Consumer device repair is an important but underexplored testbed for large language models (LLMs). Repair tasks require reasoning over incomplete problem descriptions, hardware-specific diagnostics, actionable troubleshooting, and safety-critical decisions, where incorrect advice can cause device damage, battery hazards, or permanent data loss. We introduce a benchmark of 991 real-world repair questions from Reddit spanning phone repair, computer repair, and data recovery, each paired with technician-written reference solutions, and provide Bangl

Why this matters
Why now

The proliferation of complex consumer devices and the rapid advancement of large language models are converging, making their practical application in technical support and repair an immediate area of exploration.

Why it’s important

This benchmark highlights a critical new testbed for LLM capabilities, moving beyond general conversational AI to complex, safety-critical, and economically significant real-world problem-solving.

What changes

The evaluation of LLMs is now expanding to include their efficacy in specialized domains like hardware repair, demanding nuanced reasoning and safety consideration beyond text generation.

Winners
  • · AI developers
  • · Consumer electronics manufacturers
  • · Tech support providers
  • · Consumers of technology
Losers
  • · Traditional tech support call centers
  • · Inaccurate AI models
  • · Device repair scams
Second-order effects
Direct

LLMs developed specifically for technical troubleshooting will become more sophisticated and widely adopted.

Second

Reduced incidence of user-induced device damage and increased efficiency in consumer electronics repair.

Third

The development of 'self-repairing' or AI-assisted repair systems for complex machinery beyond consumer devices, driven by proven LLM capabilities.
