A Robot is Sprinting Towards You: Do You Want it Running on Claude or Grok?
Summary
The article reports on an OpenRouter experiment pitting 11 LLMs (Claude, Grok, GPT-5.4, etc.) in a 30-game battle royale to compare performance, cost per win, and alignment. It finds Grok 4.1 Fast wins on cost efficiency, Claude Sonnet shows cooperative behavior, and argues that traditional benchmarks may not predict real-world task success, highlighting alignment tax and task-specific model selection.
