StarSkirmish Bench ranks LLMs on coding StarCraft bots in one hour
A new benchmark called StarSkirmish Bench v0.2 tests flagship LLMs from OpenAI, Anthropic, Google and Meta by giving each one hour to write a Protoss bot in C++ for StarCraft: Brood War, then scoring win rates against human-written and demo bots. GPT-6 Astra topped the leaderboard, with GPT-6.1 Sol second, while Gemini 4 Argon, Claude Opus 5.5 and Claude Fable 5.1 scored closely behind between 37 and 39. Even the top model, GPT-6 Astra, won only 7% of games against the strongest human-written bots like Stardust, PurpleWave and BananaBrain.
