I am confused why they don't just offer a subscription with bring-your-own-harness, that would be a differentiator from claude/codex I think.

Actually unless they’ve changed substantially Kimi kind of does this? It’s not as advertised/focused on and the API is a little nonstandard making it hard to plug some things into, but, unlike Claude they’ll actually give you an API key you can use directly as part of your unmetered subscription. I played with it for a month or two out of curiosity, it ls not a bad value though a bit brittle and stuff

The Chinese api prices are already so cheap that that is arguably not needed.

You can also get $10/month opencode go (which officially can be used with any harness) with basically every major open weight model running inference in a place that I deem more trustworthy than the subject-to-Chinese-law inference options (but research this for yourself, there are some asterisks). This is what I use (in opencode) when I want an agent for personal use. Even if I'm being fairly intense with my usage by my standards anyway), I haven't managed to run out (yet), although I usually use the cheaper models (deepseek v4 is my favorite, and I've used both flash and pro).

From the FAQ:

> The plan is designed primarily for international users, with models hosted in the US, EU, and Singapore for stable global access. Our providers follow a zero-retention policy and do not use your data for model training.

And:

> Yes, you can use Go with any agent. Follow the setup instructions in your preferred coding agent.

I think that pretty much all Chinese providers do that?

And Codex obviously allows that as well. Anthropic is pretty the main exception.

Negative margins to have you hooked on someone else’s software?
