More questions about Codex: 1. If I have a 200+ page thread (that now loads much faster, thank you @btraut) - how often does it reference my ChatGPT custom instructions or agents.md? Does it only reference it at the beginning of the thread? Trying to understand how well it'll follow my directions for the AI to not be sycophantic. 2. Are all these threads stored locally on my computer somewhere? Curious how much Codex is taking up.
