I can believe that (20x is not 4x of the 5x plan) but I’ve been on the $100/mo Codex and the $200/mo Claude plans and I can run the whole week with multiple agents on Claude, mean while I burned through my whole week in 1 day on Sol. Yes, it’s half the price of my Claude plan but even if OpenAi actually gave 4x usage for the next plan up (which they just halved), it would still be less than the usage I get from Claude.
I used a reset and tried Astra and it also burned though my weekly usage in a day, with a _single_ agent.
I might be totally wrong but I wonder how much is due to context window. Codex felt like it was compacting every 5 seconds, that really screws your cache reads.
