Grok 4.5 DeepSWE 得分 53% —— 比 Fable 5 便宜 90%
xAI 发布了 Grok 4.5，价格为每百万 tokens 2/6 美元，显著低于 Fable 5（10/50 美元）等竞争对手。该定价策略瞄准了一个市场转变，即效率比基准测试的微小差距更重要。
xAI released Grok 4.5, a model targeting coding and agentic workflows, with a pricing structure of $2 input and $6 output per million tokens, drastically undercutting competitors like Fable 5 ($10/$50) and Opus 4.8 ($5/$25). benchmark results are competitive but variable: Grok 4.5 scores 83.3% on Terminal Bench 2.1, nearly matching GPT 5.5, but falls behind on DeepSWE 1.1 with 53% compared to Fable 5's 70%. xai claims the model uses 4.2 times fewer tokens than Opus 4.8 on SWE Bench Pro, positioning it as the most efficient option in its performance tier despite raw accuracy gaps. available now via Grok Build and Cursor, excluding the EU, this release signals a price war where vendors trade minor accuracy losses for massive cost savings.
