The engine, and everything around it

Claude Code, Codex, Kimi and Qwen, compared for non-developers

For somebody who does not write code, the differences between coding agents matter far less than two practical things: whether reaching a first prompt is just signing in, and whether the cost is a flat subscription or metered per use. Everything else is detail you will not notice.

Why a metered key is a different thing entirely

An engine that needs an API key billed per request is a different product for a non-technical person, however good the model is. It reintroduces the meter, and with it the rationing. A flat subscription you already pay for is the only arrangement where building freely costs nothing extra.

On free tiers

Be careful staking anything on somebody else's free tier. Several have closed with no notice a non-technical user could act on, taking projects with them. If a free story is worth having, it should run on hardware you own rather than on a promotion.

In Ura, Claude Code and Codex are on the shelf and Kimi and Qwen are one toggle away in Settings. None of them is second class: hide Claude and make Qwen your default if that suits your day.
