Because you basically get a discount to use claude code via subscription when using an anthropic model, compared to what you pay via api billing with another harness
Understood. Personally that's actually another good reason to boycott Anthropic: beside the fact I perceive their models as (at best) marginally better than the ones I'm used to (Z.ai glm-5.3-flash, DeepSeek Flash v4.1), they even force me to use their bloated harness. They are not even open weights and iirc they're even encrypting chain of thoughts now? Litterally, from my perspective there seems to be no reason wha…
If I really need to, I can escalate a task to Opus at $25/1M, and the results are good, but not 5000% as good.
