I tried using omp, and really like the interface, but I found it used tokens much much quicker than the Claude cli. Some simple tasks would use all the session tokens in less than an hour, as where I could get easily get 3-4 hours with Claude. Both set to use opus 4.8 auto effort. I tried tweaking the models for agents down to haiku and sonnet in omp, but didn't notice any real difference in the speed tokens were being used.
