OpenCode Zen GPT-5.2 Codex install model fails (ProviderModelNotFoundError) #8587
Closed as not planned
Description
Repro (from opencode github install):
- Install flow: Provider = OpenCode Zen, Model = GPT-5.2 Codex. Installer adds
.github/workflows/opencode.ymlwithmodel: opencode/gpt-5.2-codex. - Action fails with
ProviderModelNotFoundError. https://opencode.ai/zen/v1/modelslistsgpt-5.2-codex.- Switching workflow to
model: gpt-5.2-codexfails: "Model must be in the format provider/model".
Expected: the installer should emit a model string that both passes CLI validation and resolves, or the models endpoint should return provider-prefixed IDs consistent with the CLI.

I have Zen set up with an API key in my repo, so it should have recognized the model ID
opencode/gpt-5.2-codex. Odd.[-]Model list shows bare IDs but CLI requires provider/model[/-][+]OpenCode Zen GPT-5.2 Codex install model fails (ProviderModelNotFoundError)[/+]rekram1-node commentedon Jan 15, 2026

@rekram1-node Same with Copilot, I have the model enabled, but it just won't work.

I'd like to work on this. The root cause is a race condition:
Provider.state()resolves from the bundled snapshot before the backgroundModelsDev.refresh()completes, so models added to models.dev after the snapshot was built aren't found. Fix tracks the initial refresh promise and awaits it before computing provider state.PR: #15609
