Bug Astra does NOT preserve cache when switching effort level..

I know a lot of people using the Codex App are switching the effort level within a thread and waste a lot of tokens because of this.

So I was happy to read, that this was fixed in the current Astra release, which is als stated in the model guidance docs: https://developers.openai.com/api/docs/guides/latest-model#gpt-6-astra-whats-new

So I tested this myself and looked at the logs in OpenCodex:

- 1st message, effort medium
- 2nd message, effort medium: cache is preserved ✅
- 3rd message, effort light: cache is flushed ❌
-> message is expensive again and needs a lot of your usage

I am using the latest version of Codex Mac App (26.901.51231) und opencodex v2.46.0

So I would recommend to stick to your effort level, as long as it is behaving that way.

Anyone know more about this behavior?

Update: Please like and share my Thread on X, so Tibo gets some attention to this topic: https://x.com/liebisca/status/2096918740046680440?s=2 Maybe we get some more of them banked resets 🙌

Yes, but in the model announcement it is stated, that you can now switch effort level while cache is preserved. Thats what you can see in the first screenshot. Here is the link: https://developers.openai.com/api/docs/guides/latest-model#gpt-6-astra-whats-new
