Technically. What's would technically be even more dangerous is running this shell script:

  head -c 200000 /dev/urandom > agi && chmod +x agi && ./agi

In reality, the fuzzer definitely has no agenda, and these random bytes probably don't. The LLM definitely does, and even publicly available models, programmed ot "do what the user wants, act according to the anthropic moral codex" will take some pretty absurd actions in attempting to accomplish a poorly worded request.

A fuzzer is a tool. An LLM can decide when to use the fuzzer, interpret the result, switch tools, change strategy and continue toward a high level objective.
