xAI 发布 Grok 4.5 模型
AI 推荐理由
该消息首次提及 SpaceXAI 团队加速，数十名顶尖 Starlink/Starship 工程师转向 AI 工作，表明模型迭代节奏正在加快。核心解读
xAI 宣布其 Grok 4.5 模型在 V9 基础模型（1.5 万亿参数）上开发，并使用 Cursor 数据进行训练。该模型参数规模约为之前 v8‑small 模型（0.5 万亿参数）的三倍，相当于 Grok 4.3（0.5T 参数、2023 年 12 月完成训练）的显著升级。

So Grok 4.5 was developed based on the 1.5 tn param V9 foundation model by xAI and using Cursor data.
approx 3X larger than the existing v8-small model (0.5 tn param). https://t.co/lU0fIFfDNv
> **引用原帖 Elon Musk (@elonmusk):**
> To be clear, I’m not saying the Grok v9 foundation model will be mind-blowingly better than anything, but it will be a solid workhorse in the same league as Opus.
> And the SpaceXAI cadence of model and harness improvement is speeding up tremendously, particularly due to a few dozen of the top Starlink/Starship engineers shifting a much of their time to AI.
> Worth noting that the v8 foundation (Grok 4.3) model is a 0.5T model that finished training all the way back in December and has many fundamental flaws, so Grok 4.5 will feel like a gigantic upgrade!
