OpenAI 将合并 ChatGPT 与 Codex 额度，按 token 计费
OpenAI 把 ChatGPT 和 Codex 的额度合并成一个 token 池，12 月生效，重度写代码的人聊天额度也会被吃掉，订阅前得看看。
OpenAI 在官方文档宣布，Plus、Pro 和 Business 计划下的 ChatGPT 与 Codex 将共用同一份 token 额度。变更从 12 月开始，届时 7 月推出的智能体产品 ChatGPT Work（基于 Codex 构建）的 agentic 功能会并入主 ChatGPT。目前 ChatGPT 普通对话按消息条数计费，例如 GPT-6 Pro 有每周消息上限；切换后每次请求将按 token 定价。由于 Work 已与 Codex 共享限额，而普通聊天此前独立计量，重度写代码的用户此后会直接消耗聊天额度。
OpenAI announced on its official doc page that it will make ChatGPT and Codex draw from 1 shared token allowance on Plus, Pro and Business plans.
The change starts in December, when OpenAI moves the agentic features of ChatGPT Work, its July agent built on Codex, into the main ChatGPT experience.
Work already shares Codex’s limits, while ordinary ChatGPT chats run on a separate meter, so heavy coding today leaves chat untouched.
After the switch, each request is priced by tokens. Currently ordinary ChatGPT chats your limit isn’t set by tokens. It’s set by message counts per model, such as a weekly cap on GPT-6 Pro messages
