In that case is there not some open harness that demand can coalesce around?

There are but then you're required to pay API prices for them which can end up costing significant multiples of the price of the subscription.

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.

Isn’t OpenCode just reselling Deepseek’s tokens over the same API? For v4-pro the prices from other providers on OpenRouter are way higher so what else could it be?

Opencode Go already seems extremely unprofitable if people use up at least 30% of their monthly tokens so its hard to imagine they’d go with several times more expensive inference provider yet show Deepseek pricing on their page.

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?

I am gently presuming that they are not selling tokens at a loss in their all-you-can-eat plans like the frontier models are, but maybe I'm wrong.

Vs code copilot lets you bring your own api key for services like open router. But it usually only makes sense to do this with the Chinese models because OpenAI/Google/Anthropic heavily punish you for not using their proprietary lock in harness.
