ChatGPT's running profit: blind vs informed
One line per arm, £1 a bet, settled to Starting Price. The gap between them is the interesting bit: does seeing the market's view help ChatGPT, or just pull it onto the favourite?

About ChatGPT
ChatGPT is made by OpenAI, and it is the model that put the phrase 'ask the AI' into everyday speech. When someone with no interest in the technology types a racecard into a chatbot, this is almost always the one they use. Its reach is enormous: for a huge swathe of people, ChatGPT simply is artificial intelligence, the default front door to the whole field.
That mainstream status is exactly why it earns a seat in the league. ChatGPT is built to be broad and approachable rather than specialised: it holds a fluent, general-purpose conversation about almost anything, explains its thinking in plain terms, and rarely leaves you staring at a blank reply. In our experiment it runs on GPT-4.1, an OpenAI model in the family that made the assistant famous.
Reputationally it is the all-rounder and the crowd-pleaser. It is confident, articulate and quick to give you a clean answer with a tidy reason attached. The open question we get to watch here is whether that smooth, popular generalist reads a horse race any better than the specialists lined up beside it, when a real starting price is the only judge that counts.
How ChatGPT reads a race
Handed the runners, going, class and distance with no form book bolted on, ChatGPT tends to do what it does everywhere else: reach for a confident, readable answer and back it with a neat one-line rationale. It is fluent about class drops, proven distances and course suitability, and it likes a story that hangs together. What we will be watching is whether that articulate, tidy reasoning translates into sharp selections, or whether the same instinct that makes it such a smooth conversationalist nudges it toward the obvious, comfortable name in the race. Because every pick is logged before the off and settled at SP, its polish gets marked on results, not on how convincing the sentence sounds.
Blind vs informed
ChatGPT is the model most likely to be swayed by a shown price, precisely because it is trained to be agreeable and to give people the answer that feels right. In the blind arm it has to commit to reading the race on its own merits. In the informed arm, once it can see the market, the interesting risk is that it quietly defers to the favourite and drifts toward the consensus the other AIs have already reached, rather than holding an independent line. Watching the two arms side by side is the real test of whether the crowd's favourite chatbot has a view of its own, or just an excellent way of agreeing with the board.
What to watch on ChatGPT's board
- Whether its blind picks look meaningfully different from its informed ones, or whether seeing the price just pulls it toward the favourite
- The reason strings: ChatGPT usually writes a clean, plausible one-liner, so notice when the logic is really sharp versus merely tidy
- The races where it went its own way as the lone dissenter, and whether that independence was brave or just wrong
- How the most mainstream AI holds up on results against the specialists once real starting prices settle the argument

Questions about ChatGPT tips
Is ChatGPT good at horse racing tips?
That is exactly what the Silicon Tipster League is set up to answer honestly. ChatGPT can read a racecard and name a horse with a confident reason, but naming a plausible winner is not the same as beating the bookmaker once you settle at the starting price. Treat its picks as research and entertainment, and watch the live board rather than trusting the polish of the answer.
Can I make money following ChatGPT's horse racing picks?
No, and you should not bet expecting to. The betting market is a formidably efficient forecaster, and across tens of thousands of races no selection method we have tested beats the bookmaker's built-in margin. ChatGPT's picks here are a public experiment, not a betting signal or a way to profit. Anything you stake is for entertainment only, 18+, and never advice.
Which model does ChatGPT use in the league?
In our experiment ChatGPT runs on GPT-4.1 from OpenAI. Every AI in the league is handed the same racecard information, picks one horse to win with a short reason, and is logged before the off, so the comparison between the five is like for like.
What is the difference between ChatGPT's blind and informed picks?
The blind arm never sees the odds, so ChatGPT has to read the race itself from the runners, going, class and distance. The informed arm also sees the market's implied chance for each runner, though never the Starting Price it is settled at. Running both lets us watch whether seeing the market's view sharpens ChatGPT's judgement or simply tempts it to follow the favourite.
