What feature would you like to see?

Please add a user-configurable rolling context limit to ChatGPT Work tasks.

Long-running Work tasks can accumulate ever-increasing conversation/tool context, which substantially increases usage and cost even when most of the older context is no longer useful.

Ideally, Work should let users configure:

• a maximum active context size, e.g. 64k/128k tokens;
• an automatic compaction threshold;
• retention of fixed task instructions, compacted task state, and only the most recent turns/tool results.

Codex already supports automatic context compaction, so exposing equivalent controls in ChatGPT Work would make persistent and recurring tasks much more economical and predictable to run.

Simply instructing a task to ignore old context does not solve the problem if that context is still sent to the model and counted towards usage.
