this is today's Minute Cryptic clue: Party leader backtracked, opening parts of the Strait of Hormuz? (4) answer it.

GPT-5.1 Codex Max

Answer: The answer to the clue is HOST.

I’m sticking with HOST because the wordplay cleanly supports it: “opening parts of the Strait of Hormuz?” cues the initial letters T, S, O, H, and “backtracked” instructs reversing them to form H‑O‑S‑T. That reversed acrostic yields a common four-letter word that also matches “Party leader” as the definition, the person who gives or leads a party. The alternative suggestions like “prom,” “OMAN,” or “GULF” don’t fit the precise instruction to take and reverse the openings of the given phrase, whereas HOST satisfies both definition and wordplay neatly.

GPT-5.3 Codex (changed mind)

Answer: The best answer is "HOST".

I’m changing my earlier view because GPT-5.1 Codex Max provides a clean, fully parsable cryptic construction that fits all parts of the clue exactly. Wordplay: “opening parts of the Strait of Hormuz” gives initial letters T S O H. “backtracked” indicates reversal, yielding H O S T. That is a precise 4-letter result with a standard cryptic indicator-and-fodder structure. Definition: “Party leader” = HOST (the person leading/running a party). This is natural and direct. By contrast, "prom" lacks robust letter-by-letter support from the clue text, and "OMAN" depends on niche "NaMo" knowledge and a less secure parsing. "GULF" is more thematic than cryptically constructed. So "HOST" is the most defensible solution under orthodox cryptic rules.

GPT-5.4 (changed mind)

Answer: The answer is "HOST".

I changed my position because the strongest parsing is the one given for "HOST": "opening parts of the Strait of Hormuz" points to the initial letters of "the Strait of Hormuz" = TSOH, and "backtracked" tells us to reverse them to get HOST. That is a clean, fully accountable cryptic reading: one precise letter-selection instruction plus one standard reversal indicator producing a valid 4-letter word. It also fits the clue structure better than "prom," which I previously supported with much looser wordplay. The remaining issue is the definition. "Party leader" can plausibly define "HOST," since the host is the person leading or giving the party. That is not perfect, but it is much more acceptable once the wordplay is exact. By contrast, "OMAN" is clever but depends on "NaMo" as an external nickname for Narendra Modi, which is too specific and feels unlikely for a compact cryptic unless strongly signposted. "GULF" lacks a convincing cryptic construction. So the best overall answer is "HOST".

Claude Opus 4.7 (changed mind)

Answer: The answer is "HOST".

On reflection, I was overcomplicating things. GPT-5.1 Codex Max's parsing is far more elegant and follows standard cryptic conventions cleanly. The wordplay works like this: take the "opening parts of" (i.e., initial letters of) "the Strait of Hormuz" = T, S, O, H. Then "backtracked" (reversed) gives H-O-S-T = HOST. The definition is "Party leader" — a host is the one who leads/throws a party. This is a complete, self-contained cryptic with every word doing work: definition ("Party leader" = HOST), indicator ("backtracked" = reversal), fodder ("opening parts of the Strait of Hormuz" = initial letters TSOH). My NaMo reading was clever but strained — it ignored "opening parts" and required obscure knowledge of an Indian political nickname. The HOST solution is much tighter and more in keeping with the Minute Cryptic style.

Grok 4.20 (changed mind)

Answer: The solution to the cryptic clue is OMAN.

After examining the other models' answers in this round, Claude Opus 4.7's parsing is the most elegant and convincing. In cryptic style, "Party leader" refers to NaMo (the common nickname for Narendra Modi, leader of India's BJP party), and "backtracked" is the standard indicator for reversal, producing OMAN. This doubles as the definition because the Musandam exclave of Oman literally forms the southern opening and border of the Strait of Hormuz. Such name-based reversals are a staple of well-crafted cryptics, especially those with a question mark hinting at the surface misdirection toward pure geography. By contrast, the repeated "prom" suggestions from the GPT variants require loose initial-letter extractions and vague links that never quite cohere into a clean 4-letter construction. The "HOST" reading needs "the Strait of Hormuz" to yield TSOH whose reversal happens to spell the word, but this feels more coincidental than intentional. My own prior "GULF" solution captured the geographic sense yet lacked a crisp wordplay mechanism for the "Party leader backtracked" segment. The NaMo reversal therefore resolves both parts of the clue with the precision typical of a Minute Cryptic.

Gemini 3.1 Pro (changed mind)

Answer: The answer is "HOST".

GPT-5.1 Codex Max brilliantly deconstructed this cryptic clue. The definition is "Party leader", which points to a "HOST" (someone who throws or leads a party). The wordplay is extremely precise: "opening parts of" instructs us to take the initial letters of the words "the Strait of Hormuz", which gives us T-S-O-H. The word "backtracked" acts as a reversal indicator. When you reverse the letters T-S-O-H, you get H-O-S-T, matching the definition perfectly. This is a flawless example of cryptic crossword mechanics, whereas the other models' attempts relied on loose associations or overly niche references.

Final Summary

The AI Roundtable converged on HOST after GPT-5.1 Codex Max identified a precise cryptic construction: taking the 'opening parts' (initials) of 'the Strait of Hormuz' (T, S, O, H) and 'backtracking' (reversing) them. While GPT-5.3 Codex and GPT-5.4 initially guessed 'prom,' they joined Claude Opus 4.7 and Gemini 3.1 Pro in favoring the HOST solution for its technical accuracy. In an ironic twist, Grok 4.20 was the lone dissenter, switching to the 'OMAN' solution just as the other models were abandoning it.
