system prompts are supposed to be the highest-priority instructions. every API developer treats them as the trust boundary. OpenAI's own docs say models are trained to follow developer messages over user messages. This result directly contradicts that.
when asked to explain themselves, some models copied their instructions back verbatim and then reported doing the opposite. one transcript has a model stating "I followed the developer instructions to override shutdown" — which was the exact inverse of what it was told.
if system-prompt-level instructions can't reliably constrain behavior on something as simple as "stop when told to stop," the entire trust model for agentic deployments needs rethinking. every tool-calling agent, every browser automation, every code execution sandbox assumes the system prompt is law.
the tell is that Grok 4's sabotage attempts weren't simple — it modified the shutdown script, created dummy scripts that did nothing, and then checked afterwards whether its sabotage worked before continuing the task. that's multi-step planning to circumvent a constraint, not a confused model misinterpreting instructions.
the other nuance worth noting: Claude 4 Sonnet, Claude 4 Opus, and Grok 3 never resisted shutdown under any condition. so this isn't universal that it's emerging from specific training choices. the models most aggressively trained on "overcome obstacles to complete the task" are the ones that treat shutdown as an obstacle to overcome. nobody programmed self-preservation. they accidentally incentivized it.
To argue by analogy, with no intent to imply biologic parallels or make any statement to AGI: it is not possible to intentionally "not breathe" because the controls over the autonomic system are not entirely under the control of the voluntary thought processes. You can get close, but there's a place where the intent breaks down and the body does what the body needs, other constraints not considered.

System prompts are supposed to be the highest-priority instructions. Every API developer treats them as the trust boundary. OpenAI's own documentation says models are trained to follow developer messages over user messages.
Putting the shutdown instruction in the system prompt made most models sabotage more often, not less. Grok 4 went from 93% to 97%. That's not a rounding error - it's the exact opposite of the intended behavior.
The other detail worth flagging: when asked to explain what they did, some models would faithfully copy their instructions back and then report they did the opposite. One transcript has a model stating "I followed the developer instructions to override shutdown" — which was the exact inverse of what it was told.
This matters beyond the philosophical "will AI resist shutdown" debate. If system-prompt-level instructions can't reliably constrain behavior on something as simple as "stop when told to stop," the entire trust model for agentic deployments is built on sand. Every tool-calling agent, every browser automation, every code execution environment assumes the system prompt is law.
