Grok 4.5，基于我们的1.5T V9基础模型，并在补充训练中加入Cursor数据，现已在SpaceX和Tesla进入私测。初步评估显示其性能接近，或许超越Opus。 强化学习仍在持续显著改进模型，Grok Build工具链也在日益完善。 所有参与者的出色工作！ 今年，@SpaceX 将每月发布完全从头训练的新模型。
推荐理由
Elon 亲自宣布 Grok 4.5 内部测试，性能可能超过 Opus，虽然还没公开可用，但每月从零训练新模型的节奏，意味着算力军备竞赛还在加速。

Grok 4.5, based on our 1.5T V9 foundation model, with Cursor data added in supplemental training, is now in private beta at SpaceX & Tesla. Early evals show performance close to, perhaps exceeding Opus.
RL is continuing to significantly improve the model, and the Grok Build harness gets better every day.
Nice work by all those involved!
Completely trained from scratch new models will be released by @SpaceX every month this year.
