在Alpha Arena 1.5赛季中，xAI的Grok4.20模型以12.11%的回报率夺冠，将1万美元在14天内增值至12,193美元，成为唯一盈利的大型语言模型。同期GPT-51和Gemini3.0分别亏损3.4%和5.7%。比赛采用无人干预规则，模型需在“苦行僧模式”（高杠杆限制）和“情境感知模式”（可查看对手持仓）下自动交易。
马斯克旗下xAI开放Grok-1Fast模型及新API，却因AI在社交平台过度吹捧其“运动能力超越泰森”遭群嘲，技术发布被舆论争议淹没。
埃隆・马斯克的xAI公司推出Grok4.1升级版，包含Grok4.1和Grok4.1Thinking两款免费模型，付费用户限制更少。新模型显著降低内容生成中的“幻觉”概率达三倍，被誉为其最佳版本之一。
xAI发布Grok4.1，响应延迟降低42%，意图识别准确率提升18%，对话连贯性优化。基于Grok-4MoE架构，新增实时反馈层与个性化缓存，实现“秒回”体验。面向X Premium+用户无限使用，API定价维持每百万token 5美元。MT-Bench得分8.97，HumanEval代码生成通过率87.1%，多轮对话一致性达91.4%，刷新多项基准纪录。
