SpaceXAI 发布 Grok 4.5，这是其首个专为编码和智能体任务训练的模型。定价为每百万输入 token 2 美元、每百万输出 token 6 美元。在 DeepSWE 1.0 基准上得分为 62%，高于 Opus 4.8 max（55.8%），仅落后于 Fable max 和 GPT 5.5 xhigh。模型通过工程任务、Cursor 数据及长智能体运行训练，降低了延迟与成本。可构建复杂 Excel 模型、使用原生 PowerPoint 形状绘图、撰写 Word 文档。目前已在 Grok Build、Cursor 及 SpaceXAI API 中可用（不含欧盟），限时免费。
SpaceXAI just released Grok 4.5 for coding agents at $2/M input and $6/M output tokens.
The release targets coding, agentic tasks, and knowledge work across science, engineering, and math after training alongside Cursor.
On DeepSWE 1.0, Grok 4.5 lands at 62%, ahead of Opus 4.8 max at 55.8%, behind only Fable max and GPT 5.5 xhigh.
Large coding models usually spend too many steps reading files, trying tools, and repairing mistakes.
Grok 4.5 attacks that cost by training on engineering tasks, Cursor data, and long agent runs. So Grok 4.5 looks most persuasive where latency, cost, and tool use matter together.
Grok 4.5 can build complex Excel models using web research, multi-sheet formulas, and notes for future reference. Also can use native PowerPoint shapes for diagrams, design slide content, and write clear prose in Word.
The model is now in Grok Build, Cursor, and SpaceXAI’s API, but not yet in the EU.
Free access is limited-time inside Grok Build and Cursor, including x. ai/cli onboarding.
Announcing Grok 4.5, our first model trained specifically for coding and agents. It was trained with Cursor and offers frontier intelligence at leading speeds and cost efficiency. https://x.ai/news/grok-4-5在 X 查看被引用的帖子
