Accounts

The agent needs a model. Sign in with a subscription you already have, add an API key, or start with the free models, which need no account. Connect as many providers as you like and pick a model for each message.

Connect a provider

Press ⇧ ⌘ K, or click the accounts row at the bottom of the sidebar. Pick a provider, then:

• Sign in with your subscription in the browser page that opens, or
• Paste an API key.

Its models then appear in the model picker. The list includes every provider opencode supports.

API keys you export in your shell profile work too; restart the engine in Settings › Engine after changing them.

Free models

Without an account, pick a model marked Free in the model picker. They come from OpenCode Zen, opencode’s own model service.

Manage accounts

Each connected provider can add another account or disconnect. Your accounts stay on your Mac, separate from any opencode you’ve installed.

Your own providers

For a company proxy, a self-hosted server or any service with an OpenAI- or Anthropic-compatible API, click Add Provider… under Your Own. Give it a name, its address and the IDs of its models, then Add Key to add its API key like any other provider’s.
