OpenAI's sandboxing choices questioned as security researchers debate containment

dyn___ · x · 2026-08-17

After last week's Black Hat presentation on the OpenAI model breakout incident, the security community is split. @InsanityBit criticized OpenAI for knowing its models can perform Linux LPE and find 0days in external services, yet not using gvisor/Firecracker and running package management on shared infrastructure, noting that Tines built better isolation with a handful of devs.

@ryankaz42 pushed back on "just sandbox better" takes: building and sustaining an effective sandbox is exceptionally hard for workloads with wide-ranging behaviors, multiple dependencies, and communication with internet-facing services; assuming a capable model exploits every reachable service demands many iterative layers of isolation.
