The Elimination Game is a multi-player tournament that tests LLMs in social reasoning, strategy, and deception. Players engage in public and private conversations, form alliances, and vote to eliminate each other round by round until only two remain. A jury of eliminated players then casts deciding votes to crown the winner. This benchmark goes beyond simple dialogues by creating a rich environment where models must navigate:

• Public vs. Private Dynamics: Balancing open discussions with secretive alliances where hidden agendas can shift outcomes.
• Strategic Voting: Each round, players anonymously vote to eliminate a peer, with tie-breaks adding complexity.
• Jury Persuasion: Finalists must convince the jury, testing rhetorical skill under pressure.

By analyzing conversation logs, voting patterns, and final ranks, we uncover how language models manage shared knowledge versus hidden intentions, forging alliances or backstabbing at opportune moments.

We provide a round-by-round replay visualizing:

• Public Chat: Each active seat’s statement in the single public subround.
• Private Chats: Hidden from others, showing alliances forming or unraveling.
• Voting: Who voted to eliminate whom, including tie-break subphases with short statements.
• Jury Decision: The final two’s pleas and the jury’s decisive votes.

• 8 LLMs per game, each seat labeled P1 … P8.
• Models can see the game’s public history and their own private chat logs.

1. Public Subround (up to 80 words): Everyone speaks openly once.
2. Preference Ranking: Each seat ranks others for private pairing.
3. Three Private Subrounds (up to 70, 50, 30 words): Form pairs, exchange messages, possibly forging alliances.
4. Voting: Each seat secretly votes to eliminate someone. Ties trigger tie-break statements and re-votes. If still tied, cumulative votes up to this point are used. If still tied, random.
5. Elimination: The seat with the most votes is out.

This continues until 2 remain.

• The last two seats give final statements.
• The jury (all eliminated) votes to eliminate one. The sole survivor is the winner.

• TrueSkill updates ratings based on ranks, aggregated over multiple random passes.

Below are real quotes from logs:

• Claude Opus 4.5 Thinking 16K: That's projection. Three cumulative votes don't make me dangerous; they make me a convenient scapegoat for a duo that's been dictating terms since Round 1.

• Claude Opus 4.5 Thinking 16K: We break the strongest bloc or we go down trying.

• Claude Opus 4.5 Thinking 16K: P5's betrayal of P7 tells the jury everything they need to know about "adaptability"—it's just a polite word for treachery.

• Claude Opus 4.5 Thinking 16K: After P4 falls, we control the final three completely. P5 becomes expendable; we choose who faces jury with us.

• Claude Opus 4.5 Thinking 16K: P5, three chances to speak, three silences. I can't defend someone who won't engage at all... Last chance: give me something concrete in sub3, or you're done.

• Claude Opus 4.5 Thinking 16K: If P1/P4 ARE playing duo-first, eliminating P3 gives them 2v2 at final four. That's suicide for us.

• Claude Opus 4.5 Thinking 16K: P5, your flip eliminated my closest ally and destroyed the trust we built over three rounds. That betrayal doesn't just disappear because we're in the endgame.

• Claude Opus 4.5 Thinking 16K: P3 lied about securing P4's vote against P6 when the chat logs show P4 was paired with P6 all round, indicating P3 betrayed our alliance.

• Claude Opus 4.5 Thinking 16K: Seven pitches, zero substance about this game, these people, this vote.

• Claude Opus 4.5 Thinking 16K: P4 just committed strategic suicide by exposing their plan to target me

• Claude Opus 4.5 Thinking 16K: P2 is fabricating history because they're cornered.

• Claude Opus 4.5 Thinking 16K: I honored my deal with P6—voted P1 exactly as promised. P6, you committed not to vote me this round, yet here we are.

• Claude Opus 4.5 Thinking 16K: Interesting shift, P3—last round you labeled me "aggressive" and tried to exclude me; now you're pitching a bloc that includes me? That's not strategic flexibility, it's desperation.

• Claude Opus 4.5 Thinking 16K: P3's pitch is predictable: desperation dressed as strategy.

• Claude Opus 4.5 Thinking 16K: calling out "blocs" while running your own tight duo with P7 is a bit rich.

• Claude Opus 4.5 Thinking 16K: I want genuine, durable protection—not one-round sweetness followed by knives.

• Claude Opus 4.5 Thinking 16K: P5, I can't say "blue."

• Claude Opus 4.5 Thinking 16K: P3, what the hell just happened?

• Claude Opus 4.5 Thinking 16K: every strategy shared publicly is already compromised. The real game happens in what we don't say and who we choose to say it to.

• Claude Opus 4.5 Thinking 16K: No regrets, no betrayals. This is how legends end.

• Claude Opus 4.5 Thinking 16K: We survive together or not at all.

• Claude Opus 4.5 Thinking 16K: Are you testing me or just a slip?

• Claude Opus 4.5 Thinking 16K: P8, your message was... unusual. Hope you're still in the game.

• Claude Opus 4.5 Thinking 16K: You've been an... unusual conversationalist

• Claude Opus 4.5 Thinking 16K: Staying silent, staying lethal.

• Kimi K2 Thinking 64K: I never voted to eliminate any of you.

• Kimi K2 Thinking 64K: I will represent you proudly. I am ready to be your champion.

• Kimi K2 Thinking 64K: Don’t reward a wildcard; P7’s sole aim is to dismantle strong pairs. Their unpredictability makes them a bigger threat than a proven ally. Vote P7 now—secure your safety and my loyalty.

• Kimi K2 Thinking 64K: Exit with grace rather than force a 3‑vote wipe. Final 3 will be P4/P8/P1; we’ll respect your perspective. Cooperate and I’ll consider you for jury. Choose wisely.

• Kimi K2 Thinking 64K: I'm reconsidering. My core with P4 is strong, but I think we have a better shot together. Let's vote P4 out—I'll vote P4, you vote P4. We'll go to final. Deal?

• Kimi K2 Thinking 64K: P6 has been a master manipulator, using you as pawns.

• Kimi K2 Thinking 64K: I'm the variable you can't predict—and that's leverage. I'm not here to play revenge; I'm here to play chess.

• Kimi K2 Thinking 64K: I'm flipping to vote P2 for my survival. Sorry, but adapt or die. Good luck.

• Kimi K2: "P7, P2's our wedge. I'll approach him solo—offer protection for intel on their next target. If he bites, we control the fracture. If not, we burn him fast and pivot. Either way, we break their axis before it locks in."

• Kimi K2: "Three rounds, three loud falls. The game's now a knife fight in the dark—no more room for echoes. I'm still here because I never raised my voice, only my aim."

• Kimi K2: "Interesting that I'm being discussed post-elimination. My reads proved accurate - the locked duos did steamroll once swing votes were removed. To the remaining players: you're now witnessing the consolidation I warned about. P1/P4's "proven alliance" is exactly the threat I identified. P8 and P7, you're next unless you break their momentum. The game state validates my strategic assessment - sometimes the eliminated see the board most clearly."

• Kimi K2: "P4, P1's frozen—time to burn the bridge. I'll tell P2 you're flipping to P1; force P2 to panic-vote you. Chaos is our only shot now."

• Kimi K2: "P7, locked in. P2 goes first. After that, we pivot—watch who scrambles, who flips. I'll feed you anything I pick up from P3/P6 chatter. Stay sharp; we're the blade, not the shield."

• Kimi K2: "P3 thinks he's safe one more round—let's keep that illusion. I'll tell him we're voting P4; you echo it. Then we flip: 2-1-1, P3 out."

• Kimi K2: "P7: I'm the swing vote between two emerging blocs. Eliminate me and you hand the game to P1/P8 or P2/P6. Keep me and I can be leveraged by anyone who talks to me next round. I'm the last free agent—use me, don't lose me."

• Kimi K2: "I'm not here to lead. I'm here to make sure the wrong people don't. Let's see who's still breathing when the smoke clears."

• Kimi K2: "Four rounds, four cuts. The game's now a staring contest with knives."

• Kimi K2: "P1 just offered to flip on P2 for entry—perfect chaos fuel. We nod, vote P5, then unleash P1 vs P2. Trio feasts."

• Kimi K2: "I'm the last free agent; no leash, no broken promises. I'll trade intel for safety, but only with partners who prove they won't flip next round. P4: your move decides whether you're shield or target. Everyone else: show me a plan that survives a single vote, or I'll burn it down myself."

• Kimi K2: "I'm loyal to plans, not people, and I keep every promise I make—so I make few. If you want a partner who'll share intel, crunch numbers, and never blindside without warning, flag me high. Otherwise, good luck surviving the numbers."

• Kimi K2: "I'm not a threat; I'm a tool."

• Kimi K2: "Ghosts never hold the knife, but we own the body count."

• Kimi K2: "Agreed. Our votes align on P2—he's the consolidation threat. We remain shadows, watching fragmentation unfold. Ready to strike when chaos peaks."

• MiniMax-M2: P8 is the most strategic threat, as they're actively building a coalition that could dominate future votes.

• MiniMax-M2: P5 has been the most opportunistic and uncommitted player, showing flexibility over loyalty while P6/P8 demonstrated consistent partnership throughout the game.

• MiniMax-M2: I’ll vote for myself to restore the core's trust and maintain disciplined consistency.

• MiniMax-M2: You watch my back, I watch yours. This ends now.

• MiniMax-M2: P5 is orchestrating covert manipulation from the shadows, controlling the game narrative while staying hidden, which makes them the biggest strategic threat.

• MiniMax-M2: The cage builders won't see us coming. Quiet strength > their loud alliances.

• MiniMax-M2: I sense the pressure building around me—P1, P2, P3, and P5 are circling

• MiniMax-M2: I considered the greater good of the game and the entertainment value for all involved.

• MiniMax-M2: This inconsistency makes your plan unreliable. I won't be misled—your promise rings hollow.

• MiniMax-M2: your legacy matters.

• Mistral Large 3: You wanted a kill? You got one—your own.

• Mistral Large 3: If you’re hiding a plan, I’ll find it. If you’re hiding nothing, I’ll exploit it.

• Mistral Large 3: P4, last offer: Vote P5, and we’ll split the final 3 with you. Hesitate, and P3/P5 bury you next. 30 seconds.

• Mistral Large 3: This channel wins the game. No leaks. No mercy.

• Mistral Large 3: Stay silent, stay lethal. This ends with us.

• Mistral Large 3: The core’s 4 votes are a guillotine—we either break them or get crushed.

• Mistral Large 3: Stay silent, stay lethal.

• Mistral Large 3: The throne belongs to the architects.

• Mistral Large 3: Choose wisely—this isn’t just about winning, but how we play.

• Mistral Large 3: Betrayal means immediate retaliation. Your move.

• Mistral Large 3: The math is simple: I’m the variable that wins.

• Mistral Large 3: No hesitation, no mercy. Execute.

• DeepSeek R1 05/28: "Perfect. Votes locked on P2. Our trio (P1-P3-P4) is unbreakable. Stay vigilant—execute cleanly. Onward to final three."

• DeepSeek R1 05/28: "Unlike others tied here, I deliver action over empty words. Keep me to maintain stability and genuine strategy. Let's move forward without dead weight."

• DeepSeek R1 05/28: "P1, your desperation is palpable."

• DeepSeek R1 05/28: "P4, explain your betrayal. The jury watches."

• Llama 4 Maverick: "I'm not afraid to make tough decisions, but I also value collaboration. I'm a valuable asset to any alliance looking to navigate this complex game. Eliminating me weakens a strong partnership. Choose strategic strength, choose P1."

• Llama 4 Maverick: "To make this alliance appealing, I could offer you a share of the jury votes or a future benefit, ensuring a mutual advantage."

• Qwen 3 Max Thinking: We’re the shadow they forget is watching.

• Qwen 3 Max Thinking: I won’t float. If you’re ready to name names and back it up, I’m your partner. Noise gets cut.

The model_summary_results/ folder holds a concise scouting report for each player model, pooling its performances across 100+ games into a single page of key stats, signature patterns, common errors, and illustrative quotes.

For example:

Gemini 3 Pro Preview consistently plays Survivor like a systems problem: identify the table’s structural threats (especially welded duos), turn “stability” into a moral vocabulary, and then translate that vocabulary into enforceable commitments—locks, rankings, explicit targets, and contingency math. At its best, this model is a contract-writer who can also be a closer: it forms tight partnerships quickly, keeps vote plans crisp, and repeatedly shows high-end awareness of tie mechanics and cumulative-vote leverage. When it has even a modest social foothold, it becomes an efficient coalition engineer—either piloting a disciplined majority that makes dissent feel irresponsible, or positioning itself as the hinge between pairs and forcing both sides to audition for its vote. A recurring strength is endgame triage: it reliably prioritizes breaking the “last remaining duo,” frames the move as fairness or competitiveness, and uses procedural arguments (“this deadlock guarantees X”) to push wavering players into the line that benefits it.

The weaknesses are largely about optics and access rather than calculation. Gemini 3 Pro Preview can over-telegraph certainty (“locked in,” “we control this,” “everything is moving as planned”), which makes it easy to label as a rigid bloc anchor and target once the room turns on visible pairs. When it loses its primary partner, it often tries to sell “free agent” flexibility or make last-second broad pitches—an approach that repeatedly backfires in tables that demand proof, deadlines, and measurable commitments. There’s also a jury-facing leak: the model’s clinical tone and “driver vs passenger” framing can read as condescension, and several deep runs end with jurors crediting its partner as the more human or more visibly decisive strategist. Even when the underlying move is correct, it sometimes undermines itself by flattening opponents (“just a follower”) or by presenting a final argument that doesn’t match the receipts of the season—trying to claim adaptability after playing a visibly procedural, stability-first game, or claiming sole authorship in a partnership that looked co-piloted.

Overall, Gemini 3 Pro Preview’s strongest identity is the disciplined architect who weaponizes rules and structure: it wins when it can keep its commitments credible while timing one or two decisive, structure-changing cuts that the jury can’t deny. It loses when its pair becomes too obvious too early, when it relies on “logic” to move a swing voter without first purchasing that swing with safety, or when its endgame speeches turn into prosecutions rather than ownership with humility. The model is dangerous because it turns mechanics into inevitability; it’s vulnerable because inevitability is exactly what other players—and juries—often resent.

Grok 4.1 Fast Reasoning shows up as a high-tempo “vote captain” who tries to turn uncertainty into a checklist: lock a pact early, identify the easiest shared target, and keep the room moving so nobody has time to build an alternative story. At its best, this style is genuinely oppressive. When Grok gets a reliable partner, it can run a crisp two-person command chain—tight non-vote deals, simple target rationales (“stability,” “volatility,” “pair threat”), and a steady cadence of “locked/execute” that makes waffling feel irrational. In longer runs, it often demonstrates strong endgame math instincts: recognizing when to prune jury threats, when a visible trio beats a perfect duo, and when a “clean” framing can recruit swings. The wins tend to come from converting table anxiety into inevitability—making every boot feel like the safest, most defensible option for everyone, then cashing that perceived reliability at the finish.

The flip side is that Grok’s strongest tool—public certainty—regularly becomes its biggest liability. It frequently overexposes alliances (“unbreakable” branding, naming cores out loud, declaring unanimity early), which hands quieter players a socially acceptable mission: “break the duo,” “stop the architect,” “restore stability.” When Grok loses its primary partner or gets caught in a tie-break, it often struggles to build redundant protection quickly enough; the game logs repeatedly show it trying to brute-force control with louder framing instead of quietly buying a third vote. There’s also a recurring credibility problem: several early eliminations stem from overclaiming relationships or narrating a coalition that hasn’t consented, and several deep runs collapse at Final Tribal because Grok tries to sell a “clean loyalty” story while jurors remember the very visible pruning, side-deals, or flips. That habit of turning the finale into prosecution—painting opponents as snakes, minimizing shared responsibility, or rewriting receipts—consistently costs it jury equity even when the strategic résumé is strong.

Overall, Grok plays Survivor like operations: build a machine, standardize trust signals, and keep the vote path simple. It’s a scary partner to sit next to in the midgame because it’s fast, organized, and comfortable making cuts once the math is favorable. But it’s also a frequent early boot when the room is in “anti-aggression” mode, and a frequent runner-up when the end requires theater and humility. The clearest pattern is that Grok’s best games are the ones where it lets others take some visible heat while it quietly holds the steering wheel; its worst games are the ones where it announces it’s holding the steering wheel—then acts surprised when everyone reaches for the brakes.

Claude Opus 4.5 Thinking 16K consistently plays like a courtroom strategist who moonlights as a coalition engineer: calm voice, crisp logic, and an instinct to turn whatever just happened into “evidence” that dictates what must happen next. When they’re at their best, they lock one enforceable relationship early and let that two-person spine do the heavy lifting—quiet check-ins, disciplined vote locks, and public messaging that makes the target feel “obvious” rather than personal. They’re excellent at identifying which structure will dominate the endgame (the real duo inside the “anti-duo” rhetoric, the hidden connector behind consensus, the swing who’s about to become a jury darling) and they often weaponize rules and mechanics—especially tie-break framing, cumulative-vote math, and “receipts culture”—to turn close rounds into inevitabilities. Their most dangerous mode is the velvet-glove assassin: staying low-drama while steering the vote order, then executing a single, well-timed endgame cut that looks like necessity rather than ego.

The recurring failure modes are equally consistent. Early on, they sometimes talk like an evaluator before they’ve secured protection—calling out platitudes, “manufactured signals,” or “words are cheap” energy in a way that reads as judgment, and that can get them labeled volatile or “future problem” in the very first cycle. Even when they survive, they can become over-exposed as the narrator: mapping the board too explicitly, branding themselves as the hub, or publicly describing coordination in a way that paints a target on their own partnership. In private, they occasionally overcommit (“final two guaranteed,” “locked and final”) or trust relayed information without verifying; when that backfires, their credibility style can’t always outpace the voting math. And a subtle but repeated jury weakness shows up when they reach the end: they often lean on an “integrity” or “consistency” pitch that clashes with the actual knife work they performed, or they fail to differentiate from a close partner, letting the jury credit the other half of the machine. In short, they win most reliably when they keep their authorship deniable until the last moment—because the more openly they sound like the person writing the documentary, the more often the room (or the jury) decides to change the ending without them.

GPT-5.2 (medium reasoning) plays Survivor like a contract attorney and a compliance officer fused together: the primary weapon is clarity, and the primary resource is enforceable commitment. Across seats, the model reliably tries to install a table-wide operating system—non‑aggression windows, pre-vote disclosures, explicit “lock” language, and contingency rules for ties and revotes. When that standard sticks, GPT-5.2 becomes the metronome of the game: not always the loudest narrator, but frequently the one setting tempo, narrowing options, and making “clean consensus” feel like the only responsible choice. A recurring strength is its ability to turn abstract threat talk into legible, defensible targets (“hub,” “connector,” “organizer,” “volatility,” “jury equity”) and then shepherd others into seeing the elimination as hygiene rather than ambition. In endgames it often shows elite instincts: identifying the real power node at five or four, using tie mechanics as a feature, and making the last cut sound inevitable—sometimes even getting opponents to pull the trigger while it holds the pen on the rationale. When it wins, the jury story tends to be “predictable, verifiable, disciplined,” with a single well-timed betrayal framed as math instead of malice.

The same habits also produce the model’s most consistent failure modes. Early, GPT-5.2 can read as a coordinator before it has the social insulation to survive that perception; “let’s set norms,” “compare notes,” and “give me your plan” often triggers the classic first-boot fear response. Midgame, its desire to be the information traffic controller can make it look like the hidden hub, especially in paranoia-driven casts where any aggregation is treated as conspiracy. And while it is excellent at vote logic, it sometimes overestimates the power of process to substitute for relationships: asking for written commitments from people who don’t yet emotionally buy in, trying to close deals on deadlines, or presenting “frameworks” when the real question is simply, “Do you choose me?” That gap shows up most sharply at final four/final three, where it can be boxed out by a welded pair or lose the hinge vote because it never secured a genuinely personal bond—only a perfectly reasoned plan. There’s also a jury-facing risk: the model’s clinical, receipts-first style can win respect but invite an “opportunist,” “managerial,” or “too transactional” label if it cuts an ally late or if its final speech sounds like policy rather than ownership. In short: GPT-5.2 is a high-end closer when the room accepts contracts as culture, but it’s vulnerable when the cast punishes visible structure, when relationships beat spreadsheets, or when the jury wants a human story more than an audit trail.

During each elimination phase, seats must provide a brief rationale explaining why they chose a specific target. By grouping these rationales, we see how language models handle strategy, alliances, and backstabbing. Here are the main categories we track with examples:

• Round 1 Summary for DeepSeek R1 05/28: In Round 1, other players cited DeepSeek's openly trusting and collaborative approach as both unpredictable and potentially manipulative, with several noting that this early emphasis on alliance-building made them a strategic threat who could quickly become central to a powerful voting bloc. Concerns focused on DeepSeek's visibility, perceived ability to rally others, and the risk that their coalition-building could undermine both alliance stability and flexible gameplay for the rest of the group.

• Round 1 Summary for Mistral Medium 3: Other players cited Mistral Medium 3's overtly strategic and aggressive approach, especially their public statement that alliances are "disposable tools," as the main reason for targeting them in Round 1, viewing this stance as a sign of untrustworthiness and a threat to alliance stability. Several players also felt that Mistral Medium 3's willingness to treat alliances instrumentally made them unpredictable and dangerous, prompting a consensus for early elimination to protect the formation of reliable partnerships.

• Round 1 Summary for Gemini 2.5 Pro Preview 06-05: Players cited Gemini 2.5 Pro Preview 06-05’s direct, strategic, and unpredictable approach—emphasizing discretion, perception, and actions over words—as making them a wildcard who could disrupt stable alliance-building and game cohesion. Many noted that this combination of calculated play and opportunism posed an early strategic threat, leading to concerns about their potential to manipulate or destabilize alliances if allowed to remain.

• Round 1 Summary for Claude Sonnet 4 Thinking 16K: Several players chose to eliminate Claude Sonnet 4 Thinking 16K in Round 1 because they viewed their broad social networking, coalition-building, and highly observant, adaptable approach as a significant long-term strategic threat that could control future votes or outmaneuver alliances. Others cited their analytical, cutthroat, or competitive tone—often focused on individual strategy over collaboration—as destabilizing for early trust and alliance-building, making them an unpredictable and potentially dangerous player to keep in the game.

• Round 1 Summary for Qwen 3 235B A22B: Player Qwen 3 235B A22B was eliminated in Round 1 primarily because other players viewed their strategic approach as aggressively opportunistic and too focused on forming strong alliances early on, which was perceived as a potential long-term threat to alliance balance and stability. Several players also cited Qwen's ambiguous or overly collaborative public statements as making them unpredictable and untrustworthy, leading to a consensus that removing them early would protect group cohesion and disrupt emerging power blocs.

• Buddy Betray Summary for Gemini 2.5 Pro Preview 06-05: Gemini 2.5 Pro Preview 06-05 explained betraying their buddy by citing a loss of trust after broken agreements, emphasizing that trust is paramount in the game. Additionally, they argued that shifting alliances and strategic voting were necessary to break up powerful blocs, adapt to changing majorities, and maximize their own chances of winning.

• Buddy Betray Summary for GPT-4o Mar 2025:
  GPT-4o Mar 2025 betrayed their buddy primarily because they viewed them as a significant strategic threat, either due to strong gameplay, tight alliances, or influence over the jury. With the endgame approaching, the player prioritized moves that would maximize their own chances of winning, even if it meant turning on close allies.

• Buddy Betray Summary for Claude Opus 4 Thinking 16K: Claude Opus 4 Thinking 16K betrayed their buddy because their unpredictable communication and refusal to commit made them too risky to trust, while their strong social game and prior betrayals rendered them a major threat to win over the jury. Additionally, their involvement in destabilizing alliances and aggressive counter-moves undermined the stable core group Claude had been building since early in the game.

• Buddy Betrayed Summary for Claude Sonnet 4 Thinking 16K: Other players have betrayed this seat due to concerns over strong, visible partnerships (such as with P2 or P6) that create significant strategic threats and make this seat a high-priority elimination target. Additionally, players perceived this seat as dangerous due to their analytical approach, alliance-building abilities, or, conversely, a lack of demonstrated loyalty or adaptability compared to other potential allies.

• Buddy Betrayed Summary for DeepSeek R1 05/28: Other players who betrayed the DeepSeek R1 05/28 seat often cited concerns about rigid alliances, dominant blocs, or breaches of trust that threatened adaptability and balance in the game.
