Grok 4.5 基于 xAI 的 1.5 万亿参数 V9 基础模型开发，并使用了 Cursor 数据，规模约为现有 v8-small 模型（0.5 万亿参数）的 3 倍。Elon Musk 指出，v8 基础模型（Grok 4.3）于 12 月完成训练，存在许多根本性缺陷，因此 Grok 4.5 将是一次巨大升级。他还强调，SpaceXAI 的模型和优化改进节奏正大幅加快，部分得益于数十名顶尖 Starlink/Starship 工程师将大量时间转向 AI。Grok V9 基础模型将是一个与 Opus 同级别的可靠工作马。

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).
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!在 X 查看被引用的帖子
