馬斯克旗下xAI開放Grok-1Fast模型及新API，卻因AI在社交平臺過度吹捧其“運動能力超越泰森”遭羣嘲，技術發佈被輿論爭議淹沒。
埃隆・馬斯克的xAI公司推出Grok4.1升級版，包含Grok4.1和Grok4.1Thinking兩款免費模型，付費用戶限制更少。新模型顯著降低內容生成中的“幻覺”概率達三倍，被譽爲其最佳版本之一。
xAI發佈Grok4.1，響應延遲降低42%，意圖識別準確率提升18%，對話連貫性優化。基於Grok-4MoE架構，新增實時反饋層與個性化緩存，實現“秒回”體驗。面向X Premium+用戶無限使用，API定價維持每百萬token 5美元。MT-Bench得分8.97，HumanEval代碼生成通過率87.1%，多輪對話一致性達91.4%，刷新多項基準紀錄。
