Harness: opencode

Subscription: opencode go

I also use a claw agent[1] via Telegram, which uses pi.dev under the hood with my opencode go subscription.

[1] I forked one of those Claw projects (bareclaw) and made many changes to it.

Not OP, but having explored the field a good bit, Openrouter + pi harness in a devcontainer work great as a sane starting point.

Highly recommend as a clean way to try out the upstart models.
