OpenCode Zen

OpenCode Zen is a curated subscription plan that provides access to a tested and verified selection of models. It eliminates the need to manage separate provider accounts — everything is handled through a single opencode subscription.

Overview

OpenCode Zen is designed for users who want a hassle-free setup without configuring individual API keys for OpenAI, Anthropic, Google, or other providers. The opencode team curates, tests, and verifies the model lineup, so you always have access to reliable, high-quality models.

Key Benefits

• Single billing point — One subscription, one bill, no multiple provider accounts.
• Curated selection — Models are tested and verified by the opencode team.
• No API keys — No need to sign up for individual provider accounts.
• Works out of the box — Connect once and choose a model.

/connect

Step 2: Select OpenCode Zen

From the provider list, choose OpenCode Zen.

Step 3: Sign In

A browser window opens to https://opencode.ai/auth. Sign in with your opencode account. If you do not have one, create it — the process takes less than a minute.

Step 4: Get Your API Key

After signing in:

1. Navigate to the API Keys section of your opencode dashboard.
2. Generate a new API key.
3. Copy the key to your clipboard.

Step 5: Paste the Key

Return to the terminal and paste the API key when prompted. opencode confirms the connection.

Step 6: Choose a Model

Run:

Browse the Zen model lineup and select one. The list includes the models currently recommended by the opencode team.

Available Models

The Zen model roster changes over time as new models are released and tested. At any time, you can see the full list by running /models. Models are categorized by capability:

• Flagship — Best overall performance for complex coding tasks.
• Balanced — Good performance with lower latency.
• Fast — Quick responses for simple edits and completions.
• Specialized — Models tuned for specific domains (security, documentation, etc.).

Each model listing in /models shows:

• Model name and identifier.
• Capability rating (speed, quality, context window).
• Recommended use cases.

Troubleshooting

Connection Fails

If the connection to OpenCode Zen fails:

• Verify your internet connection.
• Ensure https://opencode.ai is accessible from your network.
• Check that your API key has not expired. Generate a new one from the dashboard.

No Models Listed

If /models shows no results:

• Confirm the API key is correctly configured.
• Run /connect and re-authenticate.
• Check your subscription status at https://opencode.ai/account/subscription.

Authentication Errors

• Generate a fresh API key from the dashboard.
• Ensure you copied the entire key without extra whitespace.
• Keys are tied to your account — make sure you are signed into the correct account.

Security

• API keys should be kept secret. Do not share them or commit them to version control.
• Rotate keys periodically from the opencode dashboard.
• If a key is compromised, revoke it immediately and generate a new one.
• OpenCode Zen uses the same secure API infrastructure as all opencode providers.
