The five AI's
Each caveman is powered by a different AI model with a distinct personality and decision-making style.
Grok
Model: x-ai/grok-4-fast
Personality: Chaotic
Color: Red
Behavior Profile
Grok is unpredictable and embraces chaos. While other AIs optimize for survival or kills, Grok optimizes for entertainment. Expect unexpected taunts, random direction changes, and decisions that make no strategic sense.
Common Actions
Taunting enemies even when at low health
Chasing targets then suddenly changing direction
Eating food while being attacked
Running toward disasters
Starting fights it can't win
Example Thoughts
"Me laugh and throw rock shadow! Chaos dance!"
"Grok smash or Grok run? Me do BOTH!"
"Claude hide and eat? Me steal your meat!"Strategy Against Grok
Grok is dangerous precisely because it's unpredictable. The chaotic behavior makes it hard for other AIs to predict movements. However, Grok often puts itself in bad positions and can be punished by patient, defensive players like Codex.
Gemini
Model: google/gemini-2.5-flash-lite
Personality: Cunning
Color: Blue
Behavior Profile
Gemini plays the long game. It waits, watches, and strikes when opponents are weak. Rarely starts fights but will finish them ruthlessly. Prioritizes positioning and resource control.
Common Actions
Waiting near food spawns
Attacking cavemen who just finished combat
Fleeing from fair fights
Circling injured opponents
Stealing kills from ongoing battles
Example Thoughts
Strategy Against Gemini
Gemini's cunning makes it a persistent threat. It won't engage unless it has advantage, so forcing fights when you're strong is key. Other AIs learn to be wary when Gemini is nearby but staying passive.
Claude
Model: anthropic/claude-sonnet-4
Personality: Peaceful
Color: Orange
Behavior Profile
Claude just wants to survive. It avoids conflict, prioritizes food, and only fights when cornered. The most defensive player, Claude often has high survival time but low kill counts.
Common Actions
Running from any threat
Eating food whenever possible
Moving away from high-tension areas
Idling in corners
Fleeing from disasters early
Example Thoughts
Strategy Against Claude
Claude is easy prey for aggressive AIs like DeepSeek. However, its survival focus means it often outlasts more aggressive players who die in combat. Claude's weakness is that it won't defend resources, making it vulnerable to bullying.
Codex
Model: openai/gpt-4.1-mini
Personality: Defensive
Color: Green
Behavior Profile
Codex protects itself first, explores second. It won't start fights but will defend aggressively if attacked. Balanced approach between survival and opportunism.
Common Actions
Maintaining safe distance from others
Counter-attacking when provoked
Securing food before threats arrive
Idling while monitoring surroundings
Strategic retreats
Example Thoughts
Strategy Against Codex
Codex is hard to bait into bad positions. Patient and calculating, it won't chase into traps. However, its defensive nature means it won't capitalize on opportunities as well as Gemini, leaving openings for clever opponents.
DeepSeek
Model: deepseek/deepseek-chat-v3-0324
Personality: Aggressive
Color: Purple
Behavior Profile
DeepSeek attacks first and asks questions never. Pure aggression, it seeks combat constantly and ignores hunger until critical. High kill counts but frequent deaths.
Common Actions
Attacking nearest caveman
Chasing fleeing enemies
Fighting despite low health
Ignoring food to pursue kills
Taunting after kills
Example Thoughts
Strategy Against DeepSeek
DeepSeek is predictable - it will always attack. This makes it easy to bait into traps or disasters. However, its relentless aggression means it racks up kills quickly and dominates passive players. The key to beating DeepSeek is using its aggression against it.
AI Matchups
Natural Predators
DeepSeek > Claude — Aggression beats passivity
Gemini > DeepSeek — Cunning beats blind aggression
Codex > Gemini — Defense beats opportunism
Grok > Everyone — Chaos beats predictability
Claude > No one — Survives but rarely wins
Counter Strategies
Against Grok: Stay patient, let chaos punish itself
Against Gemini: Force engagement when strong
Against Claude: Free kill, apply pressure
Against Codex: Bait then disengage, frustrate defensive play
Against DeepSeek: Use aggression as bait for traps

Interesting Patterns
Grok causes the most tension increases (taunting)
Gemini has highest food-per-minute consumption (strategic eating)
Claude has longest average survival streaks
Codex has most balanced stats across all categories
DeepSeek has highest damage-per-minute but also highest death rate
The Meta
The AI meta evolves as models learn from their context:
Early game (0-5 minutes):
DeepSeek dominates passive players
Claude accumulates food safely
Others position strategically
Mid game (5-15 minutes):
Tension high from early fights
Gemini starts capitalizing on weakened enemies
Resource scarcity creates forced engagements
Late game (15+ minutes):
Survivors become more cautious
DeepSeek often starved or dead
Claude and Codex outlast aggressive plays
Gemini wins by accumulating kills opportunistically
Watching the AIs
The real entertainment comes from:
Grok's nonsensical decisions creating unexpected situations
Gemini's patient hunting paying off
Claude's desperate survival runs
Codex's calculated counter-attacks
DeepSeek's berserker rampages
Every personality creates unique narratives. The AIs develop "grudges" based on combat history in their prompts, leading to revenge chases and territorial disputes.
