Verified quick facts

OpenCode at a glance

Only source-tracked facts are shown.

Source-tracked cost boundary

No universal monthly total is shown when access and model usage follow separate billing paths.

The open-source client does not establish the cost of the selected model provider.
OpenCode Zen is optional; direct provider and local-model paths have separate billing.
Compare model rates and expected agent loops before estimating monthly cost.
