Before a group locks a hard yes, someone is sometimes asked to rebuild the case against it at full strength. Not a caricature. Not a cheap jab. The strongest fair version of the opposing case, stated as a serious person would state it, then a quiet pause to see whether the original decision still deserves the commit. People call that move steelmanning. Founders, operators, and leads reach for it when their own brief already sounds tidy, the room is warm to the plan, and a weak opposing sketch would only flatter the close.
pingpong is built for that classic steelman ask on web and iOS. You state one decision as you would make it, name what committing costs (money, people, dates, public words), and run a sequential five-model pass under a steelman frame. Default order: Grok, then Perplexity, then ChatGPT, then Gemini, then Claude. Later labs see your question and the prior passes, so they can fortify the opposing case instead of polishing your pitch.

What "steelman your decision" means in the room
Anthropologically, steelmanning is a hospitality rule for disagreement. The group already leans toward one answer. Someone is licensed to take the opposing brief and make it as strong as a fair opponent would, without mocking it into straw. The ritual shows up in philosophy seminars, product reviews, capital talks, and family money meetings for the same reason: a decision that only survives a cartoon critique was never tested. You are not asking for sabotage. You are asking whether your yes still holds after the other side gets its best day in court.
That is distinct from classic devil's advocacy, which licenses dissent and other-side argument without requiring the opposing case to be rebuilt at its strongest. It is also distinct from red-teaming, which leans toward attack and breakage, and from a pre-mortem, which jumps forward and treats the bet as already failed. Steelmanning stays in the present tense: construct the best competing case, then decide.
It is not medical second opinion. It is not demographic fairness tooling, not an uptime SLA, and not legal, financial, or HR advice. Neighboring buyer language lives elsewhere: Argue both sides is sequential yes-and-no language for one decision before commit; Validate your decision is confirmation-oriented language for checking whether the reasoning is sound before commit; Check your reasoning is a chain audit of premise, inference, and conclusion under sequential challenge before commit; Devil's advocate your decision is classic other-side dissent for one decision before commit; Pre-mortem your decision is classic imagine-it-failed language for one decision before commit; Red-team your decision is an adversarial sequential panel on one founder/operator bet before commit; Poke holes in your plan is conversational approval-gate language for a plan you are about to greenlight; Challenge your assumption names the hidden premise under a decision and invites sequential challenge before commit; Stress-test your memo is sequential load on an IC memo, board memo, or one-pager before you circulate; Stress-test your deck is sequential load on pitch slides and narrative before a raise send or board pre-read; Find holes in your strategy is markup on a drafted strategy memo or deck before the meeting; Second-guess your plan is adversarial review of a plan you already like before spend, announce, or ship; Pressure-test a decision names the load-test metaphor on one bet before you act; AI decision review treats the decision as the artifact under inspection; AI second opinion covers less-correlated review of an AI answer; Multi-model AI review maps category shapes; Decision insurance is metaphor, not a financial product; When to use pingpong is the timing chooser; Catch AI mistakes before you commit is the habit framing; For founders and For executives are role pages.
It is also not the before you commit ritual hub. That hub indexes scene-specific pauses (hire, pricing, launch, contract, partner, and the rest). Cluster index for pressure and adversarial buyer phrases: adversarial decision review. This page answers the buyer who already speaks classic steelman language: build the strongest fair opposing case for one decision, then decide, through a sequential five-model pass before commit.
How the sequential steelman pass works
Paste one question that states the decision as you would make it, plus what a soft opposing case costs once you commit: budget you cannot claw back easily, a hire or vendor lock, a public date, a partner promise, a board expectation. Frame the ask as a steelman: rebuild the opposing case at full fair strength, then say whether the original yes still holds. Grok drafts first. Perplexity reviews with that draft in view. ChatGPT, Gemini, and Claude follow in order. Each later model sees your question, the prior answers, and a review frame that can agree, correct, restructure, or reject a soft claim. You leave with a final answer and the earlier passes if you want to see where the opposing case gained muscle.
The handoff is the point. A single chat that helped assemble the case for the decision will often protect the rationale that made the draft feel clean. A later lab, asked to fortify the opposing brief rather than cheerlead the close, plays the charitable-opponent role groups used to assign to a careful colleague. A strong opposing case that still loses is useful. Matching "looks solid" with no friction is not. Unresolved split is a checklist for you before commit, not a reason to force a synthetic consensus.
Architecture contrast: Sequential vs parallel AI. Research notes: sycophancy, self-correction limits, Debias AI (decision rubber-stamping, not demographic fairness), Extreme reliability (decision reliability, not infra).
When steelmanning earns its keep
Steelman your decision when you already lean yes, the room is polite or aligned, and reversing after commit is expensive. Pricing change. Senior hire. Partnership. Kill or keep a line of work. Public statement. Capital raise terms. The decision is named. Your commit is the irreversible click. Concrete scene pages for other irreversible clicks live under the before you commit hub.
Skip it for early brainstorming, title polish, and choices you can reverse before anyone else feels them. One strong model is enough when being wrong costs almost nothing. Role pages for who tends to run the pass: founders, executives, consultants, investors, lawyers, product managers, teams.
How to run it without outsourcing judgment
Bring the decision you will actually make, not a straw man. State constraints and the cost of a weak opposing sketch once you act. Ask the chain to rebuild the opposing case at fair full strength, then judge whether your yes still holds. Read the middle passes, not only the final line. Treat independent convergence on the same opposing pillar as a stronger signal than polite agreement. Escalate what the chain cannot settle to counsel, finance, or domain experts. pingpong runs the steelman on the AI-shaped decision you were about to commit. It does not replace the people who own the outcome.
