Grok Build 上线长期记忆功能，跨会话同步项目细节
xAI 于 2026 年 9 月 16 日宣布在 Grok Build 中推出长期记忆功能。该功能在每轮对话后于后台自动提取有长期价值的内容，包括团队编码习惯、架构决策原因和关键项目事实，并过滤临时任务状态、未成熟推断、机密信息及代码库和文档已覆盖的内容。记忆按项目分别存储，另有全局用户偏好；支持通过 /dream 命令或后台定期将零散笔记整理合并为按主题的 Markdown 参考文件。用户回到项目时，Grok Build 会先读取相关背景知识，若当前对话的临时指令与历史记忆冲突，则以最新指令优先。更新还新增 /memory 只读浏览界面和 /dream 手动整理命令。该功能已面向所有新会话开放，运行 /new 或启动新 grok 会话并在首轮交互后即自动启用后台记忆捕获。
AI推荐理由 xAI 官方宣布 Grok Build 上线长期记忆功能，正文给出了具体机制：每轮对话后后台自动提取有长期价值的内容，过滤临时任务状态、未成熟推断和机密信息；按项目分别存储并保留全局用户偏好；支持 /dream 命令或后台定期将零散笔记整理合并为按主题的 Markdown 参考文件；新会话自动读取相关背景知识，当前指令与历史记忆冲突时以最新指令优先；新增 /memory 只读浏览界面和 /dream 手动触发命令。这些是面向 AI 编程助手跨会话上下文丢失痛点的具体产品更新，对开发者有实际参考价值。局限在于来源为 AIbase 转述，未提供官方公告链接或独立验证，且正文未给出记忆容量、准确率或隐私处理细节，效果描述仍属官方口径。

Grok Build Launches Long-Term Memory Feature for Seamless Project Detail Synchronization Across Sessions

One of the most frustrating issues for developers when using an AI coding assistant is having to re-explain the project's basic structure, code standards, and operating instructions every time they start a new session. To address this pain point, xAI officially announced the launch of a new memory feature in Grok Build on September 16, 2026, allowing the AI to automatically carry forward core decisions and project facts from previous sessions into the next work steps.
On the working mechanism, this memory function runs silently in the background. After each conversation round, Grok Build automatically reviews and extracts content with long-term value without interrupting the current operation, including the team's coding habits, the reasons behind architectural decisions, and key project facts (such as the location of a subsystem or specific test commands). It should be noted that the system automatically filters out temporary task states, immature inferences, confidential information, and content already covered in the code repository and documentation.
Regarding storage and organization, the system saves notes separately by project and has a set of global user preferences. To prevent fragmented information from piling up, the system supports using the /dream command or running periodically in the background to organize and merge scattered notes into professional Markdown reference files by topic (such as a dedicated topic document for testing standards). When users return to a project, Grok Build will automatically read the relevant background knowledge before starting work. If temporary instructions in the current conversation conflict with historical memories, the system will always prioritize the latest instructions.
To allow developers to keep track of the AI's memory status, this update also introduced two practical new commands. By entering the /memory command, users can bring up a read-only browser interface grouped by scope, intuitively preview and check the contents of all memory files, and quickly locate the corresponding file for editing if there are any errors. Through the /dream command, users can manually trigger the thematic summarization and organization of notes.
Currently, this long-term memory feature has been officially launched in Grok Build and is available for all new sessions. Developers just need to run /new or start a new grok session, and the system will automatically activate background memory capture after completing the first round of interaction.
