xAI 发布 Grok 4.5，以更低成本挑战 GPT-5.5 和 Claude · 追踪 10 个来源

作者 PulseAugur 编辑部 · [15 个来源] ·

xAI 推出了 Grok 4.5，这是一款定位为市场强劲竞争者的新型 AI 模型，尤其擅长编码和代理任务。它拥有显著更大的 500,000 个 token 上下文窗口，并提供极具竞争力的定价，据报道其成本是 GPT-4o 和 Claude 等模型的一半。虽然 Grok 4.5 在 token 效率和性能方面表现出色，尤其是在编码基准测试中，但一些独立评估表明，在某些原始质量指标上，它可能尚未达到 Fable 5 或 GPT-5.5 等顶级模型的绝对水平。 AI

影响 Grok 4.5 的激进定价和 token 效率可能会给竞争对手带来压力，并加速高容量任务的采用。
