Summary<\/p>\n

Claude Code sim lets LLMs helm virtual yachts using world-state inputs every 5s.<\/p>\n

Gemini 4 Argon won easily; GPT-6 Astra 2nd, Claude Opus stalled, Qwen visited a beach.<\/p>\n

The leading theory says Gemini’s spatial awareness (for Maps\/Earth) gave it an edge over the others.<\/p>\n

If you gave Claude Opus 5.5, GPT-6 Astra, and Gemini 4 Argon a yacht each, then told them to sail across a body of water and back with weather conditions, who do you think will win?<\/p>\n

While it’d be a very expensive project to do (both in terms of getting the boats and feeding each LLM with credits), someone has done the next best thing. They used Claude Code to make a realistic boat-racing simulator, then tasked the frontier LLM models with a virtual race.<\/p>\n

Claude Code created a sailing arena for four AI models to duke it out<\/p>\n

The results were wildly varied<\/p>\n

Over on the ClaudeAI subreddit, user abhi3188<\/a> showed off what they made in Claude Code. It’s a sailing simulator that allows an LLM to take the helm of a virtual yacht and sail back and forth across a body of water. As for the sailors, abhi3188 picked Claude Opus 5.5, GPT-6 Astra, Gemini 4 Argon, and Qwen 3.5-9B, the latter of which they admit they “threw it in there for fun.”<\/p>\n

Here’s how the boat race worked:<\/p>\n

Every 5 secs each model gets the full state of the world (23 raw numbers like heading, speed, wind, where the next mark is etc) and sets its helm and sails. No sailing tips. The sim pauses while it thinks, so slow models aren’t punished.<\/p>\n

As for the race, Qwen came in dead last, seemingly refusing to race and instead visiting a nearby beach. Despite having a hand in coding the sim, Claude Opus 5.5 came in third after it stalled on the way home and timed out. GPT-6 Astra finished second after completing a full lap, and Gemini 4 Argon secured an easy win at 1\/5th the token cost of Astra.<\/p>\n

People speculated why Gemini was the superior sailor here, and one leading theory is that Google gave it superior spatial awareness because they also want to use it in Google Maps and Earth. Either way, I think I’d enjoy more of these AI duels. Battlebots, anyone?<\/p>\n
