Grok 4.5在Artificial Analysis的AA-Briefcase基准中获得1328分，成本仅为Claude Opus 4.8的一半，展示了在性能和成本之间的优异平衡
Try @Grok 4.5!
@ArtificialAnlys Grok 4.5 是 AA-Briefcase 上表现最好的非 Anthropic 模型，在前沿的代理知识工作能力与领先的成本和时间效率方面达到了最佳平衡点。昨天 @SpaceXAI 发布了 Grok 4.5，这是一个新的前沿级模型，在代理编码和知识工作方面表现出色。在 AA-Briefcase 上，Grok 4.5 得分为 1328，比 Grok 4.3 提高了 578 分，并成为任何非 Anthropic 模型中得分最高的（请注意 GPT-5.6 尚未发布）。它在成本和时间效率方面也位于前沿，平均每个任务只需 $1.12，比 Claude Opus 4.8 (max) 低 86%，每个任务平均 12.4 分钟，约为 Opus 4.8 (max) 的一半时间。AA-Briefcase 是我们新的专有代理知识工作基准测试，它在数千个复杂输入文件上测试模型的真实任务。这些任务需要生成可交付成果，如电子表格、演示文稿和 UI 模拟，性能综合到单个 AA-Briefcase Elo 中，评估正确性、分析质量和演示质量。Grok 4.5 在高推理模式下在 AA-Briefcase 上的关键结果：➤ 前沿代理知识工作能力：Grok 4.5 获得了 1328 的 AA-Briefcase Elo 分数，成为任何非 Anthropic 模型中得分最高的，仅次于 Claude Fable 5 (1390)、Claude Sonnet 5 (max, 1390) 和 Claude Opus 4.8 (max, 1354)。在三个 AA-Briefcase 评分维度上，Grok 4.5 在客观评分标准和分析质量方面最强，但演示质量相对较弱。它获得了第二高的整体评分通过率 (40.7%)，仅次于 Claude Fable 5 (56%) 和 Claude Sonnet 5 (42.3%) ➤ 领先的成本效率：Grok 4.5 在每个 AA-Briefcase 任务上的平均成本为 $1.12，使其位于成本-性能帕累托前沿。这比同类模型如 Claude Opus 4.8 (max, $8.26) 和 GLM 5.2 (max, $1.71) 高效得多 ➤ 更快的任务完成：Grok 4.5 在每个 AA-Briefcase 任务上的平均时间为 12.4 分钟，也位于速度-性能前沿。它比 Claude Opus 4.8 (max, 23.9 分钟) 和 Claude Sonnet 5 (max, 36.9 分钟) 快得多，主要是因为使用了更少的轮次。Grok 4.5 平均每个任务只需 23 个轮次，约为 GLM 5.2 (max, 56) 的 40% 和 Claude Sonnet 5 (max, 183) 的 13% 恭喜 @SpaceXAI、@cursor_ai 和 @elonmusk 取得了令人印象深刻的成果！
Grok 4.5 is the top non-Anthropic model on AA-Briefcase, combining frontier agentic knowledge work capabilities with leading cost and time-efficiency
Yesterday @SpaceXAI released Grok 4.5, a new frontier-level model with strengths in agentic coding and knowledge work. On AA-Briefcase, Grok 4.5 scores 1328, a +578 improvement over Grok 4.3 and the highest score of any non-Anthropic model (note that GPT-5.6 not released yet). It achieves this while sitting on the cost and time efficiency frontier, averaging $1.12 per task, 86% lower than Claude Opus 4.8 (max), and 12.4 minutes per task, around half the time of Opus 4.8 (max).
AA-Briefcase is our new proprietary benchmark for agentic knowledge work, testing models on a fully private dataset of realistic tasks across thousands of complex input files. Tasks require deliverables like spreadsheets, presentations, and UI mock-ups, with performance combined into a single AA-Briefcase Elo across correctness, analytical quality, and presentation quality.
Key results for Grok 4.5 with high reasoning on AA-Briefcase:
➤ Frontier agentic knowledge work capabilities: Grok 4.5 achieves an AA-Briefcase Elo of 1328, the highest score of any non-Anthropic model, behind only Claude Fable 5 (1390), Claude Sonnet 5 (max, 1390), and Claude Opus 4.8 (max, 1354). Across the three AA-Briefcase scoring axes, Grok 4.5 is strongest on objective rubric criteria and analytical quality, with comparatively weaker presentation quality. It achieves the second-highest overall rubric pass rate (40.7%), behind Claude Fable 5 (56%) and Claude Sonnet 5 (42.3%)
➤ Leading cost efficiency: Grok 4.5 averages a cost of $1.12 per AA-Briefcase task, placing it on the cost-performance Pareto frontier. This is much most cost effective than peer models such as Claude Opus 4.8 (max, $8.26) and GLM 5.2 (max, $1.71)
➤ Faster task completion: Grok 4.5 averages 12.4 minutes per AA-Briefcase task, also placing it on the speed-performance frontier. It is much faster than Claude Opus 4.8 (max, 23.9 min) and Claude Sonnet 5 (max, 36.9 min), primarily due to lower turn use. Grok 4.5 averages just 23 turns per task, ~40% of GLM 5.2 (max, 56) and ~13% of Claude Sonnet 5 (max, 183)
Congratulations to @SpaceXAI, @cursor_ai, and @elonmusk on the impressive release!

@akashathrone @elonmusk @grok I miss grok sometimes 😕
@RebeccaJoy211 @elonmusk @grok 你们应该制作一个官方插件，让Claude和Codex可以使用Grok 4.5。
@elonmusk @grok Yall should make an official plugin that Claude and Codex can use Grok 4.5 with.
@ddball67 @elonmusk @grok 我一直在使用它。太棒了。我制作视频，使用它进行研究、草拟和执行。它高效、准确且富有洞察力。
@elonmusk @grok I use it. Sensational. I make videos. I use it for research, drafting and execution. It is efficient, accurate and insightful
@MikeKfu @elonmusk @grok 我已经无法尝试Grok了，我没有通过身份验证。
@elonmusk @grok I can't try Grok anymore. I'm not authenticated.
