Claude Platform 2026-09-24：拒绝计费变更
Claude Platform release notes — September 24, 2026
推荐理由
涉及计费逻辑直接变更与数据字段弃用，集成Claude合规接口的开发者必须调整账单处理逻辑并更新数据获取方式。
- We're resuming billing for refusals that arrive before any output when stop_details.category is "bio", "frontier_llm", or "reasoning_extraction", the categories where we measure low volumes of false positives. Mid-stream refusals were already billed. Refusals billed under this change are charged like any other request, at the rates of the model that ran it. Refusals before any output in other categories are still not billed, and fallback credit is unchanged. This change applies on all platforms. See How refusals are billed.
- The Compliance API local session endpoints are out of beta for Claude for Microsoft 365 sessions in Excel, PowerPoint, Word, and Outlook (product_surface values beginning with office_agents). See Sessions on users' machines.
- The Compliance API Activity Feed no longer returns file names, project document names, or artifact titles. The filename and title fields on file, project document, and artifact activities are now always empty or omitted, including on activities recorded before this change. To look up a name or title by the ID on the activity, use a Compliance Access Key with the read:compliance_user_data scope. See Understand the Activity object.
- 我们将恢复对在任何输出之前到达的拒绝请求进行计费，当 stop_details.category 为 "bio"、"frontier_llm" 或 "reasoning_extraction" 时，这些类别中我们衡量到的误报量较低。中途拒绝请求此前已计费。在此变更下计费的拒绝请求将像其他任何请求一样收费，按照运行该请求的模型费率计费。其他类别中在任何输出之前的拒绝请求仍不计费，回退信用额度保持不变。此变更适用于所有平台。请参阅“拒绝请求如何计费”。
- 合规 API 本地会话端点已退出测试阶段，适用于 Excel、PowerPoint、Word 和 Outlook 中的 Claude for Microsoft 365 会话（product_surface 值以 office_agents 开头）。请参阅“用户机器上的会话”。
- 合规 API 活动流不再返回文件名、项目文档名称或工件标题。文件、项目文档和工件活动的 filename 和 title 字段现在始终为空或被省略，包括在此变更之前记录的活动。要通过活动 ID 查找名称或标题，请使用具有 read:compliance_user_data 范围的合规访问密钥。请参阅“了解 Activity 对象”。
