Start chatting
Pick the model in Quick Chat. Agent Chat can use it through the OpenCode agent.

Free models that work here. Paste any model id into the client.

If Test passes but messages fail to send, edit the provider and turn on Enable CORS. Replies then arrive in one piece instead of streaming.
Keys are stored in the Obsidian keychain of each device and do not sync with the vault. Enter the key again on every device.
