OpenAI 发布 GPT-5.6 模型家族，包括旗舰 Sol、均衡 Terra 与高性价比 Luna。新一代通过底层技术栈深度优化，大幅提升每 token 智能效率，在降低 API 成本的同时增强性能。其中，旗舰 Sol 开启最大推理能力后，在编码智能体基准测试中表现超越竞品。
OpenRouter推出提示词缓存与粘性路由技术，通过复用多轮对话中重复的系统指令、工具定义等不变内容，大幅降低智能体交互的token消耗与成本，助力长时间智能体应用普及。
大模型服务主战场正转向检索增强问答、多文档摘要和长程Agent。请求prompt由几十到上百个语义独立的片段（检索文档、技能说明、记忆、历史轮次）拼接，形成数万至数十万token的超长上下文，预填充阶段占据主导算力开销，成为服务商最突出的成本来源，且引发更棘手的难题。
马斯克旗下SpaceXAI发布Grok 4.5，为上市后首个重大更新。模型定位通用主力，可完成代码编写等任务。马斯克称其达到Opus级水平，但速度更快、Token效率更高且成本更低。
