Use OpenCode Zen and Go catalogs with OpenClaw	You want OpenCode-hosted model access You want to pick between the Zen and Go catalogs	OpenCode

OpenCode exposes two hosted catalogs in OpenClaw:

Catalog	Prefix	Runtime provider
Zen	opencode/...	opencode
Go	opencode-go/...	opencode-go

Both catalogs use the same OpenCode API key infrastructure (OPENCODE_API_KEY, alias OPENCODE_ZEN_API_KEY). Go still requires its own paid subscription; having a Zen key does not by itself grant Go access. OpenClaw keeps the runtime provider ids split so upstream per-model routing stays correct.

OpenClaw sends a stable x-opencode-session conversation header on requests to https://opencode.ai across the Anthropic, Gemini, OpenAI Chat Completions, and OpenAI Responses transports. This header remains enabled when prompt caching is disabled. Low-level SDK stream callers should supply sessionId in their stream options.

Standalone openclaw infer model run --local calls and the prepared completion helper generate a fresh routing header per invocation when no explicit routing header or session identifier is supplied. This generated value stays in the header and does not create a conversation or enable session-based caching. Explicit model or caller routing headers are preserved regardless of header name casing.

Getting started

**Best for:** the curated OpenCode multi-model proxy (Claude, GPT, Gemini, GLM, DeepSeek, Kimi, MiniMax, Qwen).

<Steps>
  <Step title="Run onboarding">
    ```bash
    openclaw onboard --auth-choice opencode-zen
    ```

    Or pass the key directly:

    ```bash
    openclaw onboard --opencode-zen-api-key "$OPENCODE_API_KEY"
    ```
  </Step>
  <Step title="Set a Zen model as the default">
    ```bash
    openclaw config set agents.defaults.model.primary "opencode/gpt-5.6-sol"
    ```
  </Step>
  <Step title="Verify models are available">
    ```bash
    openclaw models list --provider opencode
    ```
  </Step>
</Steps>

**Best for:** the separately subscribed Go lineup across DeepSeek, GLM, GPT, Grok, Hy3, Kimi, MiMo, MiniMax, and Qwen.

<Steps>
  <Step title="Use the bundled Go catalog">
    OpenCode Go is included with OpenClaw, so no separate
    plugin installation or Gateway restart is required.
  </Step>
  <Step title="Run onboarding">
    ```bash
    openclaw onboard --auth-choice opencode-go
    ```

    Or pass the key directly:

    ```bash
    openclaw onboard --opencode-go-api-key "$OPENCODE_API_KEY"
    ```
  </Step>
  <Step title="Set a Go model as the default">
    ```bash
    openclaw config set agents.defaults.model.primary "opencode-go/kimi-k3"
    ```
  </Step>
  <Step title="Verify models are available">
    ```bash
    openclaw models list --provider opencode-go
    ```
  </Step>
</Steps>

Config example

{
  env: { vars: { OPENCODE_API_KEY: "sk-..." } },
  agents: { defaults: { model: { primary: "opencode/gpt-5.6-sol" } } },

Provider catalogs

Zen

Property	Value
Runtime provider	opencode
Example models	opencode/gpt-5.6-sol, opencode/kimi-k3, opencode/deepseek-v4-flash

Run openclaw models list --provider opencode for the current active list. Model availability and promotional routes can change independently of OpenClaw.

Live discovery combines the models available to your OpenCode account with authoritative model metadata from https://models.opencode.ai/api.json. OpenClaw fetches and caches that catalog only when OpenCode Zen or Go is configured or explicitly selected with OpenCode credentials; startup and unrelated providers never download it. New upstream models become available without an OpenClaw update when their metadata describes a supported transport on the trusted OpenCode endpoint. A key-scoped response can omit models unavailable to that workspace. Metadata and lifecycle status refresh together; deprecated models are excluded from active discovery and its offline fallback. Deprecated explicit refs remain resolvable for existing configurations but are not shown as current recommendations.

Account-list failures produce a failed catalog outcome, not a successful seed list. A successful empty or fully filtered account response stays empty. The separate public metadata feed can still use trusted offline metadata when it is unavailable; that does not replace or retry the account-list request.

Price estimates also refresh through the hosted model catalog, using the same public OpenCode pricing feed as live discovery. Hosted updates activate after the next Gateway restart; the bundled snapshot remains available offline. Explicit model prices in your configuration or agent-local models.json keep precedence. These are advertised-price estimates, not verified invoice totals.

Go

Property	Value
Runtime provider	opencode-go
Example models	opencode-go/kimi-k3, opencode-go/deepseek-v4-flash, opencode-go/qwen3.8-max

See OpenCode Go for discovery, routing, and access requirements. Go's model-list endpoint advertises its general lineup; listing a model does not prove your account can run it.

Advanced configuration

`OPENCODE_ZEN_API_KEY` is also accepted as an alias for `OPENCODE_API_KEY`. Entering one OpenCode key during setup can store credentials for both runtime providers. It does not create a Go subscription or grant Go entitlement; subscribe to Go in the OpenCode console before using it. Create an OpenCode account and generate an API key at [opencode.ai/auth](https://opencode.ai/auth). Billing and catalog availability are managed from the OpenCode dashboard. Gemini-backed OpenCode refs stay on the proxy-Gemini path, so OpenClaw keeps Gemini thought-signature sanitation there without enabling native Gemini replay validation or bootstrap rewrites. Non-Gemini OpenCode refs keep the minimal OpenAI-compatible replay policy. Billing, retention, and training policies are model-specific. Check the current [OpenCode Zen pricing and policy](https://opencode.ai/docs/zen/) before selecting a route. Free models may be temporary feedback programs.
