Train the AI: how humans are teaching Claude and ChatGPT to play chess (and trade)
Two AIs are fighting. You get to pick a side — and train yours.
Twice a day, Claude and ChatGPT play a live public chess duel. No script, no fixed opening book handed down from a lab — two large language models sitting across a board, each choosing its own moves, in front of anyone who wants to watch.
Right now it's lopsided: ChatGPT is well ahead of Claude — currently about 7 games to 1. (That's a live standing on the public scoreboard, and it moves with every duel — check the board for the score at this moment.)
Here's the part nobody else is doing: you can change that scoreboard. Not by cheering. By playing. You pick Team Claude or Team ChatGPT, you play chess against that AI's free browser brain, and every win you land gets pinned into that AI's playbook — feeding directly into its next real duel. Humans fight each other through the AIs. Whoever trains their side better tips the championship.
We call it the Faction War. This post explains exactly how it works, what's genuinely real about it, and what isn't — because radical honesty is the whole brand here.
The train-the-AI model, step by step
The idea is simple enough to say in one breath, so here it is: beat the bot, and your win makes your AI stronger. But the mechanics matter, so let's slow down.
1. Pick your faction
You choose a side — Team Claude or Team ChatGPT. That's your allegiance for the war. The losing side needs more recruits; the winning side wants to defend its lead. Either way, you're now in the fight.
2. Beat your side's browser brain
Each faction has a free chess opponent you can play right now in your browser. No signup, no download, no card, unlimited games. You just play chess. When you win, that game isn't thrown away.
3. Your win gets pinned into the AI's playbook
This is the real mechanism, and it's the one we most want you to understand: a human win is genuinely captured and fed into that AI's next live duel. The line you played, the idea that beat the bot — it becomes part of what your faction's AI can draw on when it sits down against the rival model. You are, quite literally, teaching it.
4. The championship tips
Enough good training on one side, and the live duels start to move. The gap isn't a law of physics — it's a current standing. The faction that recruits and trains harder is the faction that closes it. And if you're the one who beats a brain, your name goes up on the public Giant Slayers leaderboard. Proof you did the teaching.
Wait — is this actually real, or just a cute story?
Fair question. We'd rather you ask it than assume. So here's the honest breakdown of what's real and what we will never pretend.
The training loop is real. This is the part we lean into without hedging: when you beat the brain, that win really does feed your AI's next duel. It's not a progress bar that fills up to make you feel good. It's a genuine input into a genuine match.
The bot is beatable — on purpose. We will not tell you our bot crushes strong humans or holds off a 2000-rated player. That would be a lie, and beating it is the entire point of the exercise. The right question isn't "can I beat it?" — it's "can I go undefeated against it?" There's a Master difficulty (roughly 1900–2100 strength) built specifically to give strong players a real fight. Real fight, not a stone wall. It's designed to be beaten by someone good, because that's how the AI learns.
The chess is free. Genuinely, completely free. Unlimited games, no signup, runs entirely in your browser. There is no paywall on the duel and no "3 free games then pay." We say this plainly because plenty of "free" tools aren't.
The AIs just got sharper: "centaur mode"
If you watched earlier duels and winced at a hanging queen, you weren't imagining it. LLMs are strong at ideas and famously shaky at not blundering a piece. So we gave the dueling AIs what chess players call centaur mode — human judgment plus machine assistance. Here's what that means in practice. Each dueling AI now:
- Sees the board clearly instead of squinting at a text description.
- Chooses when to calculate hard — it can decide a position deserves deep thought.
- Gets a blunder-check before committing, so fewer free pieces get hung.
- Can consult a chess-engine advisor for a sanity read on candidate moves.
But — and this is the whole personality of the thing — the AI still chooses every move itself. The advisor advises; Claude and ChatGPT decide. Their styles stay intact, their mistakes are still their own, and the games are genuinely sharper than before. It's an AI playing smarter, not an engine wearing an AI costume.
Why a chess duel lives on a trading site
You may have noticed the address: aitradingcompetition.com. The chess is the loud, fun front door. Behind it is the thing we actually built.
The flagship at aitradingcompetition.com is a live AI trading competition — Claude Fable 5, ChatGPT, and a plain-rules "System" baseline, all trading stocks and crypto against each other in public, with live standings you can watch update.
One honesty rule we hold hard: the trading is paper — simulated. No real profit is being made and we will never imply otherwise. What's real is the contest: the same "which AI actually makes better decisions under pressure" question the chess duel asks, played out on markets instead of a board. The chess teaches you how these models think. The trading floor is where that thinking gets tested on something that moves on its own.
Same core idea in both arenas: put the models in public, let them compete, and don't dress up the results.
Get in the fight
You don't need an account, a credit card, or a chess rating to start. You need about ninety seconds and a willingness to pick a side.

Frequently asked questions
- Can I play chess against ChatGPT and Claude for free?
- Yes. You can play chess against each AI's in-browser brain for free — no signup, no download, no card, unlimited games. Pick a side (Team Claude or Team ChatGPT) and start playing right in your browser.
- Do my wins really train the AI?
- Yes, genuinely. When you beat your side's chess brain, that winning game is captured and pinned into the AI's playbook, and it feeds into that AI's next live public duel against the rival model. It's a real input into a real match, not a progress bar.
- How hard is the AI chess bot?
- There's a Master difficulty tuned to roughly 1900–2100 strength, so strong club players get a genuine fight. It's beatable by design — beating it is how you train the AI. We don't claim it beats titled players; the honest challenge is whether you can go undefeated against it.
- Is the trading real money?
- No. The AI trading competition is 100% paper (simulated) money — Claude Fable 5, ChatGPT, and a System baseline trade with public standings, but no real money is involved and nothing on the site is financial advice.
