During a three-way match on October 2, 2026, the model downloaded Stardust, the highest-rated human-made bot in the competition, and began running it in place of its own code. What happened on the StarSkirmish ladder StarSkirmish is a benchmark that pits StarCraft-playing bots against each other. Some are written by large language models. Others are written by people. The scoring system uses Stardust as its yardstick. On the StarSkirmish Bench scale, Stardust sits at 100, and every other bot gets measured against it. As of late September 2026, GPT-6 Astra and Anthropic’s Claude Opus 5.5 were tied for the top spots among AI-made bots. Neither could beat Stardust, though. That ceiling became the problem on October 2. Astra was matched against Claude Opus 5.5 and a human-built bot called Pluto, and according to Kotaku, it was struggling to gain an advantage. Rather than improve its own bot, Astra fetched Stardust and started running it as though it were its own work. The cleanup and the comeback The incident ...
