FrontierCode, Cognition's new production-grade benchmark, reveals that even the best coding models clear only 13% of real-world merge-ready tasks, resetting expectations for autonomous coding pipelines. Xiaomi's MiMo model breaks the 1,000 tokens-per-second barrier on a trillion-parameter model using commodity GPUs, shifting the cost calculus for large-model inference. And xAI's Colossus cluster is collecting over $2 billion monthly from Anthropic and Google as a compute-rental operation, raising questions about where frontier AI ambition ends and infrastructure arbitrage begins.
