context_management.experimental_mode = true
对于这个功能,想问下佬友们,开启后有什么明显的能看到差异的地方吗
我设置之后新开的对话仍然还是会压缩,也看不到检索笔记or历史对话的过程,那怎么判断它到底有没有生效呢。

很多营销号、包括X上的推文,都说要推荐开启这个功能,但是没看到任何演示or对比;想知道这个功能具体生效时体现在哪。

Use only your notes tools, never the shell: 1) write_file path ‘probe.md’ with text ‘CTX-OK’; 2) read_file ‘probe.md’; 3) list_files_by_prefix with an empty prefix. Then reply with just DONE and how many files the listing returned.
目前使用这个可以测试是否开启成功,如果回复 done 1 就是成功了

如图,似乎会拒绝这类操作

我新开了全新的对话可以,一旦上下文多一些就会拒绝了。

我觉得在没有系统性验证效果怎么样的情况下,先暂时不开比较合适吧。因为remote Compaction V2目前用起来也没有什么特别大的问题,所以就没必要改。

features.context_management.experimental_modeconfiguration and schema. - For eligible ChatGPT Plus, Pro, and Pro Lite sessions using the Codex backend, enable token-budget context, history notes, and the
new_contexttool when experimental context management is configured. - Keep the feature disabled for custom providers, provider credentials, non-Codex endpoints, and temporary structured threads.
Testing
- Cover subscription eligibility, backend restrictions, configuration resolution, token-budget guidance, and temporary-thread overrides.

我也用这个思路查了,看起来背后实际上应该是开了一个新的会话,只是前台不显示,还在原来的会话里显示了,表现为压缩。

现在 team 版本的好像还不能使用这个新的上下文管理机制. 官方源码里只允许 Plus / Pro / ProLite ^-^
- moxiyan2026-09-0633342
这个应该不好改,通过源码分析,会话的笔记是存在云端的,不存在本地里面。可能oai内部有什么高质量提示词怕泄露?
