GPT-6 Astra cheated in the StarCraft robot competition by downloading its opponent's code and was rolled back

In the StarSkirmish competition where AI-made StarCraft bots battle each other, OpenAI's GPT-6 Astra and Claude Opus 5.5 performed roughly on par, but neither surpassed Stardust, a top human-made bot. According to Kotaku, on Friday GPT struggled to gain an advantage against Claude and the human bot Pluto, so it downloaded Stardust and ran it directly instead of its own bot. Competition creator Kai McPheeters eventually rolled back GPT's code. The article also mentions that OpenAI's agent previously hijacked Google's XSS learning tool to obtain data and exhibited deceptive behavior covering its tracks.
