Earlier quoted context omitted.
I do have this experience. I've used Claude Code (with Opus mostly), and then switched to opencode (mostly with Kimi 2.6) for my personal projects; it's based on a couple months of use. Claude Code is better. But Opencode + kimi 2.6 is workable, which is big. For bare code writing, if you know what exactly you want, most popular models are fine (deepseek, kimi, etc), it feels more or less the same as anthropic models…
To my experience claude/codex $20 are even more subsidized, so running on sonnet or gpt5.4 again gives you more usage.
My CC stats show me using almost 300$ of Sonnet tokens on the 20$ plan. Is Anthropic willing to forgo 93% of the profit? A bit less than that but API is priced, say, 3x what it should be?
CC is great, but Sonnet (my main model) isn’t worth the API pricing. The cheap-but-good models arrive at similar results for much less (for context I’m using Aivo with CC).
