16% — the median of 6 frontier models, resolving by 2027-02-04.

Answer

Gemini (Google): 23% — Clash risk turns on whether localized warning shots or drone incursions breach the DMZ threshold before February 2027. The 3-month window is narrow, but both sides have dismantled buffer-zone military agreements and resume armed DMZ post-manning. Historical base rates of physical exchanges of fire over any random quarter are under 5%, yet current zero-buffer rules elevate odds. A direct exchange of fire would require accidental crossing or drone shootdowns triggering immediate retaliatory artillery bursts.

Answer

Claude (Anthropic): 12% — Hinges on whether rising tensions and UN warnings translate into an actual armed clash, not just rhetoric or minor incidents. No direct armed DMZ clash has occurred since 1960s-era incidents despite decades of tension, favoring a low base rate even amid warnings. North Korea generally prefers missile tests, cyber ops, and rhetoric over kinetic DMZ engagement that risks uncontrolled escalation. A sudden leadership crisis, border incident, or miscalculation by frontline units within the ~15 month window would be the main path to resolution.

Answer

GPT (OpenAI): 14% — It turns on whether routine provocations breach command control and prompt an armed South Korean response before February 2027. Pyongyang and Seoul would both need to permit or fail to halt fire across the DMZ; neither has an interest in sustained war. Since the 1953 armistice, serious DMZ incidents have been rare, with the 2015 artillery exchange showing escalation can occur but be contained. A verified exchange of artillery or small-arms fire, rather than rhetoric or a maritime incident, would sharply raise the estimate.

Answer

Grok (xAI): 18% — NK/SK exchanging confirmed fire across DMZ in ~90 days. Both militaries must initiate/respond with live fire; UN alerts exist but no assassination or invasion trigger is pending. Recent DMZ clashes average ~1/decade, so 3-month base is low absent a spike like 2010 Yeonpyeong. A NK artillery barrage or SK live-fire accident would shift odds most.

Answer

DeepSeek (DeepSeek): 18% — Whether a localized provocation near the DMZ escalates into confirmed cross-border fire before February 2027. The 2018 Comprehensive Military Agreement buffer zones are effectively dead since 2023, so small arms fire or a border incursion can escalate without a formal decision… Both sides have fired warning shots and conducted live-fire drills near the DMZ in 2024-2025, but the last confirmed cross-border exchange was the 2010 Yeonpyeong… Kim Jong Un has shifted to a hostile two-state doctrine and is deepening Russia ties, raising the chance of a localized provocation that crosses the line before February…

Answer

Qwen (Alibaba): 5% — North Korea's strategic calculus still strongly penalizes initiating a DMZ clash that could trigger US response. Base rate: roughly 5-10 qualifying DMZ clashes in 70 years since armistice, giving ~2-3% per 3-month window even at baseline tension. Elevated rhetoric and UN warnings push this above base, but DPRK has consistently avoided direct cross-border fire even during 2010 and 2017 crises. A miscalculation or rogue unit firing is the most plausible path; deliberate escalation would require Kim to accept existential regime risk.
