Local-only by requirement: tracing binaries for cybersecurity research

This person's cybersecurity research work simply can't touch infrastructure they don't control, which rules cloud models out entirely. Locally, they use models for smaller, well-defined tasks inside that work — naming functions and tracing control flow through a binary — rather than open-ended analysis. Beyond the work requirement, they also describe tinkering with local models as a genuinely enjoyable hobby in its own right.
