OpenAI在OpenRouter平台匿名上线代号"Polaris Alpha"的大模型，疑似传闻中的GPT-5.1。该模型具备256K上下文窗口，知识截止至2024年10月，性能表现引发开发者密集测试。在Gemini3、Claude4.5等竞品压力下，此举被视为OpenAI年底市场竞争的重要布局。
谷歌CEO确认Gemini3大模型将于2025年发布，虽称非颠覆性突破，但旨在系统性缩小与OpenAI GPT-5的技术差距。该模型聚焦智能代理功能，依托6.5亿月活用户构建生态护城河，加速布局终端、云服务等全链条AI体系。
谷歌CEO确认年内将推出Gemini3人工智能模型，重点强化处理复杂多模态任务的"智能体"能力，旨在超越现有Gemini2.5Pro并缩小与GPT-5等对手的差距。新模型将更注重实用性与复杂性，持续提升AI性能表现。
OpenAI推出AI浏览器ChatGPT Atlas，以ChatGPT为核心引擎，直接挑战谷歌Chrome。产品免费开放，付费用户可享多步自动化Agent模式，实现从聊天到浏览的无缝融合。发布时机恰逢Gemini3传闻落地前，引发市场热议，AIbase分析其潜在颠覆力。
