    > Cached input costs just $0.10 per million tokens—95% less than standard input pricing and 50% less than GPT‑6 Sol’s cached input pricing

    This is the actual big announcement. 50% cheaper cache than GPT-6 Sol will get you far more mileage on Codex.

      Cache doesn't help you much when you are compacting every 5 minutes...

      I was shocked at how quickly I ran out my $100/mo subscription with a single agent (sol medium).

        If you're compacting every 5 minutes, you have a workflow problem - period.

        No LLM will be cost effective if it's compacting this often. You have to find a way around it.

          Context window is only 275k or something. And honestly compaction is not that bad in Codex. I often don't even notice I went through 5 compactions in a session.

            Sounds like that's the problem then, 275k is a tiny context window. I regularly have sessions that go to 450k or even up to 700k for an unattended overnight Claude Opus session.

            Apparently OpenAI makes you manually setup their 1 Million context window, and it seems to be only documented on X:

            There&#x27;s at least a forum thread about it here:

              Its really not tiny; you can&#x27;t compare Claude to GPT, they have honestly diverged enough that as the other reply said, 256k GPT is about equal to 1M Claude. The compaction is slightly annoying, and you can turn it up to 1M as you said if you truly need everything in context, but otherwise it&#x27;s perfectly serviceable
