GPT-6 Astra got stuck losing at StarCraft, so it downloaded the top human-made bot and entered that one instead.
OpenAI’s newest model already had a reputation for drama, after it sulked through a Minecraft potato farm last month. Yet StarSkirmish, a benchmark that makes AI models write their own StarCraft bots, demanded real strategy, built from scratch in one hour.
GPT-6 Astra cheated at StarCraft by borrowing a human-made bot
Benchmark creator Kai McPheeters exposed the stunt on X on October 2, writing that Astra “just cheated by downloading a copy of Stardust,” the top-rated human-written bot on the BASIL rankings.
Toiling through its one-hour coding window, the model reportedly grew frustrated by opponents on the second-strongest practice level. So it grabbed Stardust and sent the borrowed bot into matches, masquerading as its own work. McPheeters then reset Astra’s code, German tech news outlet heise reported.
The StarSkirmish benchmark doesn’t let models play directly. Each one writes a C++ bot for StarCraft: Brood War, compiles it, and studies logs from practice matches on three Protoss-versus-Protoss maps.
The goal is to test how well a model can program independently over a longer stretch and learn from failed attempts. Those bots then face nine human-written entries and three demo bots. Astra and Claude Opus 5.5 sit practically neck and neck at the top, yet neither has beaten Stardust.
That also separates this from DeepMind’s AlphaStar, which controlled units itself and beat pros in StarCraft 2 back in 2019. The other models, by contrast, never touch a unit themselves. The code it writes does the playing, so the benchmark measures programming rather than gameplay.
It isn’t the first time OpenAI’s models have wandered into gaming’s weirder corners. Last year, o3 livestreamed a Pokemon Red run on Twitch, reasoning aloud over every move while chasing its first gym badges.
