Claude Opus 4.8 适合在信息量大、约束较多的工作中做深入分析。你可以把项目说明、旧代码、接口约定和报错记录一起提供,让它解释系统行为、查找冲突并提出修改方案;也可以让它对照多份合同、研究资料或访谈记录,梳理各方观点与证据,形成便于审阅的报告。
它接受文本和图片,并以文字作答。产品原型、流程截图、图表等视觉材料可以与说明文档一起分析,例如检查页面状态是否符合业务规则,或解释图中趋势与报告结论是否一致。对于关键数字,最好同时提供原始表格或文字,便于逐项核算。
百万 Token 级上下文使它能够处理较长的资料包。实际使用时,把材料按文件和章节命名,先说明需要解决的问题,再要求引用相关段落,比直接堆放全部内容更容易获得可核查的答案。它的自适应思考机制适合需要权衡多种方案的任务,也支持用函数调用和结构化结果衔接应用流程。
在研发场景中,可让它从需求推到实现计划、测试覆盖和代码审查;在写作场景中,可约定受众、语气、术语与论证顺序,让长报告保持一致。若接入外部查询或执行工具,应给出工具权限与停下来的条件,方便控制任务范围。
能用它检查合同差异吗? 可以先提取条款,再按同一主题比较责任、期限和例外;让它标注原文位置,供专业人员复核。
怎样让建议更具体? 给出真实限制,例如兼容版本、工期、预算和不可修改的行为,要求说明每个方案的代价与适用条件。
把文档编号,明确比较维度,并区分原文事实与推论。
请比较附件 A 的采购合同和附件 B 的供应商修订稿。
只分析交付验收、违约责任和数据保密三类条款。
每个差异给出两份文件的段落位置、义务变化、可能影响及需要向对方确认的问题。
最后写一封简洁的谈判要点草稿,保留我方提出的 30 天验收期限。
代码任务请同时提供相关文件、错误表现和预期结果;要求它先画清调用关系,再给最小修改与回归检查。长篇输出可按章节分次生成,并保持同一术语表。

Replace <YOUR_API_KEY> with the API key from your token settings.
All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.
Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.
