关于 Claude Sonnet 4.5
了解 Claude Sonnet 4.5 的功能、特性以及它如何帮助您获得更好的效果。
**Agentic 智能的前沿**
Claude Sonnet 4.5 代表了 Anthropic 在“前沿智能”方面的重大飞跃，专门针对 autonomous AI agents 时代进行了优化。该 model 于 2025 年底发布，是行业内首个真正的“混合 reasoning”模型，允许开发者在常规任务的高速执行与复杂逻辑挑战的深度思考之间自由切换。它在计算机使用和工具编排方面的 benchmark 显著超越了以往，成为终端 agent 和多文件软件工程的首选引擎。
**精准度与减少 Hallucinations**
该 model 基于“三思而后行”的逻辑架构构建，显著减少了在 3.5 系列中出现的迎合性和 hallucinations 问题。凭借巨大的 64,000 token output 限制和 200,000 token input 窗口，它可以摄取整个代码仓库，并在单次执行中生成完整的应用程序文件。它还为 agentic 工作流引入了原生的 “checkpoints” 功能，允许 agents 自主回滚并纠正自己的错误。
**Multimodal 与 Reasoning 实力**
除了编程，Sonnet 4.5 在 multimodal 文档分析和复杂金融建模方面也占据主导地位。其内部逻辑经过训练，会优先考虑架构上下文，使其能够比任何前代产品更好地映射大型代码库。无论是处理手写笔记还是实现完整的 Stripe 集成，Sonnet 4.5 都能保持极高的事实准确性和指令遵循能力。

专业技巧
专家提示帮助您充分利用此模型并获得更好的效果。
善用 CLAUDE.md：在仓库根目录使用 CLAUDE.md 文件，为 model 提供简短摘要和指引；这可以将 token 浪费减少 30%。
混合 Reasoning 开关：仅在处理逻辑密集型任务时在 API 调用中使用 “thinking” parameter，以节省常规操作中的 latency 和成本。
.claude/context 文件夹：创建 .claude/context.md 文件来存储架构决策；该 model 经过专门训练，会优先通过此路径进行代码库映射。
Prompt Caching：为静态文档或大型代码库启用 prompt caching，在重复查询时可节省高达 90% 的 input 成本。
