DeepSeek官方宣布API已升级至百万Token上下文版本，与App和网页版一致，此前仅为128k tokens。这一更新显著提升了对话连贯性和信息丰富度。同时，知识库也更新至2025年5月，用户可在非联网状态下准确获取该时间点的信息。
DeepSeek发布V3.2标准版与深度思考版。评测显示，V3.2在128k上下文场景下与GPT-5互有胜负；深度思考版在多项基准测试中与Gemini3Pro持平，并在IMO2025盲测中达到金牌分数线。核心升级是转正稀疏注意力技术，通过优化token路由，显著降低了长文本的计算复杂度、显存占用，并提升了推理速度，首次在开源模型中实现了百万token的单卡推理能力。
OpenAI发布GPT-5 Pro API，具备40万Token上下文窗口，支持图像输入，可处理复杂长文本。定价为每百万Token15美元，推动AI应用普及。这是该公司迄今最强大的模型。
OpenAI发布GPT-5-Codex模型API，定价与GPT-5相同，输入token每百万1.25美元，输出token每百万10美元。该模型最大优势是400k上下文窗口，能处理更复杂信息，显著提升编程等任务效率。
