25% — the median of 6 frontier models, resolving by 2026-12-20.

Answer

Gemini (Google): 27% — Hezbollah and Israel will not consent to a formal post-UNIFIL framework without resolving border sovereignty disputes first. UNIFIL's mandate typically requires UN Security Council renewal each August; an operational handover plan cannot bypass UNSC 1701 politics. The Lebanese Armed Forces lack the domestic mandate and capacity to disarm Hezbollah without provoking internal sectarian conflict. Israel demands autonomous enforcement rights that Paris mediators and the Lebanese government cannot formally accept in a joint communique.

Answer

Claude (Anthropic): 22% — Hinges on whether Lebanon, Israel, US, and France can align on LAF-only handover terms before Dec 2026 deadline pressure builds. Multiple stakeholders (Lebanon, Israel, US, France, possibly Hezbollah-linked political actors) must all sign off, which historically slows Lebanese security deals. Base rate for multilateral Middle East security frameworks reaching a clean joint communique within a 3-month window is low given past UNIFIL mandate negotiations… A concrete trigger like a formal UN Security Council session or US-brokered summit announcement would sharply raise the odds if scheduled before December.

Answer

GPT (OpenAI): 37% — It hinges on Israel, Lebanon, and Hezbollah accepting an enforceable successor force and mandate before UNIFIL’s exit. France and the UN must first align Israel and Beirut on command, border access, arms enforcement, and funding by December. Past Lebanon security deals often yield broad communiqués but stall on Hezbollah’s disarmament and Israeli withdrawal conditions. A UN-backed force with committed troop and funding pledges, or a ceasefire collapse, would shift the odds most.

Answer

Grok (xAI): 18% — Israel-Lebanon-UN consensus on a UNIFIL handover in Paris before the Dec 20 cutoff. UNIFIL's mandate last renewed Aug 2026; any Paris plan must still clear UNSC, Beirut, and Jerusalem in ~90 days. Lebanon security accords have a near-zero 3-month success rate given Hezbollah veto power and Israeli red lines. A sudden ceasefire-plus-disarmament deal would be the only event that could lift this above 30.

Answer

DeepSeek (DeepSeek): 22% — This turns on whether Israel and Lebanon can agree on who secures the south before UNIFIL's mandate lapses. UNIFIL's mandate runs to August 2027, so no hard deadline forces a handover plan by December 2026. Israel demands Hezbollah disarm and rejects Lebanese Army-only control; Beirut refuses anything framed as disarming Hezbollah, so the core gap persists. Paris talks have produced statements, not binding frameworks; the 2024 ceasefire monitoring mechanism took months to stand up and remains fragile.

Answer

Qwen (Alibaba): 34% — Lebanon's government must consent to a plan that Hezbollah's armed presence makes politically toxic to endorse publicly. UNIFIL's mandate was renewed in Aug 2025 for one final year to Aug 2026, so the wind-down timeline is real and creates urgency, but Paris talks have produced only… Any 'agreed' plan requires Lebanese government sign-off; Hezbollah's parliamentary bloc and armed wing make formal endorsement of a foreign-led security framework… A development that would raise this sharply: a Saudi-Iranian détente signal or a direct Hezbollah concession on weapons south of the Litani, neither of which is…
