system prompt——在启动时一次性加载全部上下文。这种”静态预加载”模式忽视了一个关键事实：<b>上下文窗口是一种具有递减收益边际的有限资源</b>。</div><div class="notion-text notion-block-2b9ba467396981eab21de31c6b8db36e">这种方式存在三个根本性问题：</div><ol start="1"

Manus 的实践数据为例，Agent 的平均输入与输出 token 比例约为 100:1，这意味着预填充阶段的成本占据绝对主导。更关键的是，工具定义在序列化后通常位于上下文的前部，任何变更都会使后续所有动作和观察的 KV 缓存失效——未缓存的 token 成本可能是缓存 token 的 10 倍。</li></ol><ol start="2" class="notion-list notion-list-numbered notion-block-2b9ba46739698183b9aec9c3e6ad731c" style="list-style-type:decimal"><li><b>上下文腐烂（Context Rot）</b>。Chroma 团队的研究表明，模型性能下降受三个因素驱动：上下文长度增加导致注意力稀释、问题与关键信息的语义相似度降低、以及关键信息与周围干扰内容的语义相似度过高。这三个因素会相互放大。当 system prompt 过长时，精心设计的核心指令会被淹没在工具描述中，模型越来越难以准确匹配到真正相关的指令——即使技术上支持 128K 甚至 1M 的上下文窗口，<b>最大上下文窗口 ≠ 最佳注意力窗口</b>。</li></ol><ol start="3" class="notion-list notion-list-numbered notion-block-2b9ba467396981138624fb1fa2a5b07e" style="list-style-type:decimal"><li><b>动态性与可维护性缺失</b>。静态加载意味着想修改某个 tool

微调。之后甲方要求测试模型服务，但是不提供服务器进行部署 😅，没办法，只能租服务器部署提供远程访问。在租赁的服务器上部署模型之前，我在本地事先跑通了完整的部署和测试流程，整个过程比较简单，按照 <code class="notion-inline-code">ms-swift</code> 文档 deploy 就行（前期使用 <code

boss，看准招式，及时闪躲，切忌贪🔪。一周目的通关也是用了风灵月影的，有几个 boss 实在打不过，比如寅虎、小黄龙、杨戬，但是毒敌大王我是用毛毛流打过去的，有几个 boss 死了二三十次才过去哈哈哈，成为不了识破仙人。已经开启了二周目去刷成就，二周目就下载了一些不是很影响游戏平衡的

0.89，表现出色；但在Python转换到C++的任务中，pass@1值降低到0.67，说明该模型在处理从动态类型语言到静态类型语言的转换时可能存在局限。同时值得注意的是，<b>所有模型在Java转换到Python的任务和C++转换到Python的任务的整体表现优于其他翻译任务，可能是因为模型在训练时包括了更多的Python语料库</b>。对于专门面向编程大模型Code Llama，可以观察到在不同的翻译上任务上能力一般，说明底座模型本身的能力很重要。
<b>总而言之，不同模型在多种翻译任务中表现出显著差异，同一种模型对于不同的编程语言和翻译任务也表现出不同的能力。gpt-4-1106-preview凭借其出色的模型架构和训练方法，在该任务上展现出巨大潜力。</b>尽管现有模型在代码翻译任务上取得了不错的成绩，但仍有进一步优化的空间。未来的研究可以探索如何针对性地改进模型架构、优化训练策略，并引入更多样化的编程语料，以提升模型在代码翻译任务上的性能表现。</div><h4

红海子(迦嘎措) → 鱼子西 → 木雅大寺 → 四姑娘山 → 卧龙大熊猫基地 → 都江堰 → 成都。五天的旅程，只有第二天的天气最好，在红海子拍了很多好看的风景和合照~，最遗憾的莫过于第三天在鱼子西五点多起去看日照金山 🏔️，但是云层很厚，并没有看到什么，最神奇的是我们不甘心，有其他旅游团都走了，我们又呆了一会，眼看云层在慢慢散去，刚拍一两张照片，结果突然下雪了 ❄️，然后一分钟之内，远处的山不见踪影，雪也渐渐变大了，大部分人从原路返回，但我们的计划路线是继续往西，目前这条路下雪挺危险，幸运的是遇到一个一样开着坦克 的驴友，也要往那边走，然后两辆车相互照应，一起出发了！</div><div class="notion-row notion-block-02a543e3d45848aaae87f470649a7191"><div

🥰。哦~期间还会玩了一个卡牌游戏：uno，挺不错的，笑得腹肌都出来了 🤣。这趟旅程之前我还准备了一些药，怕自己高反，不过看起来我很健康哦，基本没有什么反应，除了爬山的时候轻微喘不上气，吸一两口就好了~，最高海拔 4500 米左右。更多 🖼️照片 👉 <b><a target="_blank" rel="noopener noreferrer" class="notion-link"
