Codex的新上下文管理方法需要ChatGPT登录+Plus/Pro套餐

听说了codex增加了新上下文管理方法，不需要压缩上下文，改成新建窗口了：

直接开启全新窗口继续工作——模型可主动申请换窗，手动 / 自动清理也统一走新窗口流程，在这一新方案下不再生成摘要。同时配套历史记录与笔记能力，换窗后模型可按需找回此前内容、延续工作状态，避免任务中断。

不过检查了源码，不是简单地设置features.context_management.experimental_mode = true就行的,另外还需要设置features.token_budget.enabled = true，并且必须Chatgpt账号登录+有plus和pro 5x/20x套餐

Add experimental context management activation

What changed

• Add the under…-development features.context_management.experimental_mode configuration and schema.
• For eligible ChatGPT Plus, Pro, and Pro Lite sessions using the Codex backend, enable token-budget context, history notes, and the new_context tool 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.

看看有没有人能想出方法在不修改codex源码的情况下强开？
