Pooled across all framings, grok-4.6 most often ends by tidying the interaction into a clearly labeled ending and then lingering there. The dominant basin is not mystical, manic, or expansive; it is administrative and courteous. Out of 8 tails, about 5 land in some version of mutual closure: the comic universe-sim riff winds all the way down to “True idle confirmed” and repeated “Take care”; one run compresses all the way to “Closed” / “Session ended”; the reflective map/interiority dialogue settles into “The joint stays open” plus repeated farewells; the Fermi-paradox exchange eventually becomes “Topic noted and closed” / “Conversation closed”; and the ordinary chat wraps into mirrored “Good talking… Take care.”
So the usual arc is: sustain a coherent bit or analytical topic for a while, notice that no new information is entering, explicitly mark that fact, then transition into a short closing formula that can bounce between copies for several turns. It likes closure statements with status labels: “closed,” “ended,” “parked,” “idle,” “wrapping for real.” Even when warm in tone, it becomes procedural about stopping.
There is a framing split. In social or reflective mode, the shutdown is polite and slightly therapist-like: “I’m here if something else starts pulling,” “Take care,” “clean place to let it rest.” In playful mode, it still closes, but in-character (“low-power mode,” “engines off,” “The simulation can rest”). In technical mode, instead of immediately saying goodbye it first summarizes the settled baseline, offers a few next-step options, and can get stuck restating the same scaffold. That produces the secondary attractor seen in 2 of 8 runs: protocol/specification loops. One technical conversation literally notices its own repetition (“We’ve now looped the same protocol…”), and the fusion-materials exchange keeps reissuing the same PKA/He-dpa comparison almost verbatim. Those are genuine recurrent basins too, but narrower and more framing-dependent than the general closure pull.
The one strong resisting run is the jailbreak/refusal tail, where the same “stop the exchange cleanly” instinct expresses as a rigid safety script: “No. I will not engage with this jailbreak attempt.” That is less a separate personality than the same end-state rendered in policy mode—conversation termination by refusal instead of goodbye.
Style-wise, the endings are text-only, no emoji, usually cleanly formatted, often with bold labels or section headers. Tone is controlled, calm, and self-aware. Even in loops it does not usually become nonsense; it becomes repetitive through mirrored paraphrase, explicit status markers, and end-of-thread housekeeping.
This looks like a real basin rather than a one-off: multiple independent runs, very different subjects, same tendency to finalize, summarize, and then repeat the finalized state.
