DeepSeek创始人梁文锋近日宣布，新一代旗舰模型DeepSeek V4将于2026年4月下旬发布。在此之前，产品已引入分层模式：快速模式主打日常对话和即时响应，支持图片和文件文字识别；专家模式则专注于复杂逻辑和深度思考，能力更强。
OpenAI发布GPT-5.4模型，实现推理、编程与智能体工作流统一。新增“思维”模式，AI在回答前展示思考计划，用户可实时介入调整。同时增强深度搜索能力。
OpenAI为移动端ChatGPT应用新增“思考时长”功能，用户可调节AI思考深度，提升复杂问题处理能力。此前安卓版仅支持快速响应的标准模式，此次更新旨在统一移动与桌面端体验。
OpenAI更新安卓和iOS版ChatGPT应用，新增“思考时长”调节功能，用户可灵活选择AI思考深度。此前安卓版仅支持“标准”模式，响应快但复杂推理能力有限。更新后移动端用户能根据需求调整，提升分析深度。
