Retested through the OpenCode CLI without an account: 1.3 timed out after 180 s, 1.2 returned "Unexpected server error"; both stay listed. Possibly needs a signed-in account that grants the training permission (not verified)

Answered a test prompt through the OpenCode CLI (opencode run) with no account

In OpenCode Zen's free list (-free models); our test call failed (server error, upstream overload or timeout)

Conditions found: the Contributor models need a signed-in Zen account with an explicit data-training opt-in, use the Responses API, and are limited to Meta's allowed regions (many RegionError reports outside the US); this explains our anonymous test failures
