The Google plugin provides access to Gemini models through Google AI Studio, plus image generation, media understanding (image/audio/video), text-to-speech, and web search via Gemini Grounding.

• Provider: google
• Auth: GEMINI_API_KEY or GOOGLE_API_KEY
• API: Google Gemini API
• Runtime option: agentRuntime.id: "google-gemini-cli" reuses Gemini CLI OAuth while keeping model refs canonical as google/*.

시작하기

Choose your preferred auth method and follow the setup steps.

**Best for:** standard Gemini API access through Google AI Studio.


  

Get an API key

    Create a free key in [Google AI Studio](https://aistudio.google.com/apikey).
  

  

Run onboarding

    ```bash
    openclaw onboard --auth-choice gemini-api-key
    ```

    Or pass the key directly:

    ```bash
    openclaw onboard --non-interactive \
      --mode local \
      --auth-choice gemini-api-key \
      --gemini-api-key "$GEMINI_API_KEY"
    ```
  

  

Set a default model

    ```json5
    {
      agents: {
        defaults: {
          model: { primary: "google/gemini-3.1-pro-preview" },
        },
      },
    }
    ```
  

  

Verify the model is available

    ```bash
    openclaw models list --provider google
    ```
  

GEMINI_API_KEY and GOOGLE_API_KEY are both accepted. Use whichever you already have configured.

With a configured API key, OpenClaw refreshes Google AI Studio's text-model
catalog from the Gemini `models.list` API. Newly released Gemini 3 Pro, Flash,
and Flash-Lite variants therefore appear in
`openclaw models list --provider google` without waiting for an OpenClaw
release. If discovery is unavailable, OpenClaw keeps the bundled fallback
catalog.




**Best for:** signing in with your Google account through Gemini CLI OAuth instead of using a separate API key.

The google-gemini-cli provider is an unofficial integration. Some users report account restrictions when using OAuth this way. Use at your own risk.

Install the Gemini CLI

    The local `gemini` command must be available on `PATH`.

    ```bash
    # Homebrew
    brew install gemini-cli

    # or npm
    npm install -g @google/gemini-cli
    ```

    OpenClaw supports both Homebrew installs and global npm installs, including
    common Windows/npm layouts.
  

  

Log in via OAuth

    ```bash
    openclaw models auth login --provider google-gemini-cli --set-default
    ```
  

  

Verify the model is available

    ```bash
    openclaw models list --provider google
    ```
  



- Default model: `google/gemini-3.1-pro-preview`
- Runtime: `google-gemini-cli`
- Alias: `gemini-cli`

Gemini 3.1 Pro's Gemini API model id is `gemini-3.1-pro-preview`. OpenClaw accepts the shorter `google/gemini-3.1-pro` as a convenience alias and normalizes it before provider calls.

**Environment variables:**

- `OPENCLAW_GEMINI_OAUTH_CLIENT_ID` / `GEMINI_CLI_OAUTH_CLIENT_ID`
- `OPENCLAW_GEMINI_OAUTH_CLIENT_SECRET` / `GEMINI_CLI_OAUTH_CLIENT_SECRET`

If Gemini CLI OAuth requests fail after login, set GOOGLE_CLOUD_PROJECT or GOOGLE_CLOUD_PROJECT_ID on the gateway host and retry.

If login fails before the browser flow starts, make sure the local gemini command is installed and on PATH.

Onboarding auto-detection lists an existing Gemini CLI login but never
auto-tests it because Gemini CLI has no tool-free probe. Choose Gemini CLI
OAuth or a Gemini API key to continue.

`google-gemini-cli/*` model refs are legacy compatibility aliases. New
configs should use `google/*` model refs plus the `google-gemini-cli`
runtime when they want local Gemini CLI execution.

google/gemini-3-pro-preview was retired on 2026-03-09; use google/gemini-3.1-pro-preview instead. Re-running Gemini API key setup (openclaw onboard --auth-choice gemini-api-key or openclaw models auth login --provider google) rewrites a stale configured default to the current model.

웹 검색

The bundled gemini web-search provider uses Gemini Google Search grounding. Configure a dedicated search key under plugins.entries.google.config.webSearch, or let it reuse models.providers.google.apiKey after GEMINI_API_KEY:

{
  plugins: {
    entries: {
      google: {
        config: {
          webSearch: {
            apiKey: "AIza...", // optional if GEMINI_API_KEY or models.providers.google.apiKey is set
            baseUrl: "https://generativelanguage.googleapis.com/v1beta", // falls back to models.providers.google.baseUrl
            model: "gemini-2.5-flash",
          },
        },
      },
    },
  },
}

Credential precedence is dedicated webSearch.apiKey, then GEMINI_API_KEY, then models.providers.google.apiKey. webSearch.baseUrl is optional and exists for operator proxies or compatible Gemini API endpoints; when omitted, Gemini web search reuses models.providers.google.baseUrl. See Gemini search for the provider-specific tool behavior.

Gemini 3 models use thinkingLevel rather than thinkingBudget. OpenClaw maps Gemini 3, Gemini 3.1, and gemini-*-latest alias reasoning controls to thinkingLevel so default/low-latency runs do not send disabled thinkingBudget values.

/think adaptive keeps Google's dynamic thinking semantics instead of choosing a fixed OpenClaw level. Gemini 3 and Gemini 3.1 omit a fixed thinkingLevel so Google can choose the level; Gemini 2.5 sends Google's dynamic sentinel thinkingBudget: -1.

Gemma 4 models (for example gemma-4-26b-a4b-it) support thinking mode. OpenClaw rewrites thinkingBudget to a supported Google thinkingLevel for Gemma 4. Setting thinking to off preserves thinking disabled instead of mapping to MINIMAL.

Gemini 2.5 Pro only works in thinking mode and rejects an explicit thinkingBudget: 0; OpenClaw strips that value for Gemini 2.5 Pro requests instead of sending it.

이미지 생성

The bundled google image-generation provider defaults to google/gemini-3.1-flash-image.

• Also supports google/gemini-3-pro-image
• Generate: up to 4 images per request
• Edit mode: enabled, up to 5 input images
• Geometry controls: size, aspectRatio, and resolution

To use Google as the default image provider:

{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "google/gemini-3.1-flash-image",
      },
    },
  },
}

See Image Generation for shared tool parameters, provider selection, and failover behavior.

비디오 생성

The bundled google plugin also registers video generation through the shared video_generate tool.

• Default video model: google/veo-3.1-fast-generate-preview
• Modes: text-to-video, image-to-video, and single-video reference flows
• Supports aspectRatio (16:9, 9:16) and resolution (720P, 1080P); audio output is not supported by Veo today
• Supported durations: 4, 6, or 8 seconds (other values snap to the nearest allowed value)

To use Google as the default video provider:

{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "google/veo-3.1-fast-generate-preview",
      },
    },
  },
}

See Video Generation for shared tool parameters, provider selection, and failover behavior.

음악 생성

The bundled google plugin also registers music generation through the shared music_generate tool.

• Default music model: google/lyria-3-clip-preview
• Also supports google/lyria-3-pro-preview
• Prompt controls: lyrics and instrumental
• Output format: mp3 by default, plus wav on google/lyria-3-pro-preview
• Reference inputs: up to 10 images
• Session-backed runs detach through the shared task/status flow, including action: "status"

To use Google as the default music provider:

{
  agents: {
    defaults: {
      musicGenerationModel: {
        primary: "google/lyria-3-clip-preview",
      },
    },
  },
}

See Music Generation for shared tool parameters, provider selection, and failover behavior.

Text-to-speech

The bundled google speech provider uses the Gemini API TTS path with gemini-3.1-flash-tts-preview.

• Default voice: Kore
• Auth: tts.providers.google.apiKey, models.providers.google.apiKey, GEMINI_API_KEY, or GOOGLE_API_KEY
• Output: WAV for regular TTS attachments, Opus for voice-note targets, PCM for Talk/telephony
• Voice-note output: Google PCM is wrapped as WAV and transcoded to 48 kHz Opus with ffmpeg

Google's batch Gemini TTS path returns generated audio in the completed generateContent response. For lowest-latency spoken conversations, use the Google realtime voice provider backed by the Gemini Live API instead of batch TTS.

To use Google as the default TTS provider:

{
  tts: {
    auto: "always",
    provider: "google",
    providers: {
      google: {
        model: "gemini-3.1-flash-tts-preview",
        speakerVoice: "Kore",
        audioProfile: "Speak professionally with a calm tone.",
      },
    },
  },
}

Gemini API TTS uses natural-language prompting for style control. Set audioProfile to prepend a reusable style prompt before the spoken text. Set speakerName when your prompt text refers to a named speaker.

Gemini API TTS also accepts expressive square-bracket audio tags in the text, such as [whispers] or [laughs]. To keep tags out of the visible chat reply while sending them to TTS, put them inside a [[tts:text]]...[[/tts:text]] block:

Here is the clean reply text.

[[tts:text]][whispers] Here is the spoken version.[[/tts:text]]

A Google Cloud Console API key restricted to the Gemini API is valid for this provider. This is not the separate Cloud Text-to-Speech API path.

Realtime voice

The bundled google plugin registers a realtime voice provider backed by the Gemini Live API for backend audio bridges such as Voice Call and Google Meet.

Setting	Config path	Default
Model	plugins.entries.voice-call.config.realtime.providers.google.model	gemini-3.1-flash-live-preview
Voice	...google.voice	Kore
Temperature	...google.temperature	(unset)
VAD start sensitivity	...google.startSensitivity	(unset)
VAD end sensitivity	...google.endSensitivity	(unset)
Silence duration	...google.silenceDurationMs	(unset)
Activity handling	...google.activityHandling	Google default, start-of-activity-interrupts
Turn coverage	...google.turnCoverage	Google default, audio-activity-and-all-video
Disable auto VAD	...google.automaticActivityDetectionDisabled	false
Session resumption	...google.sessionResumption	true
Context compression	...google.contextWindowCompression	true
API key	...google.apiKey	Falls back to models.providers.google.apiKey, GEMINI_API_KEY, or GOOGLE_API_KEY

Example Voice Call realtime config:

{
  plugins: {
    entries: {
      "voice-call": {
        enabled: true,
        config: {
          realtime: {
            enabled: true,
            provider: "google",
            providers: {
              google: {
                model: "gemini-3.1-flash-live-preview",
                speakerVoice: "Kore",
                activityHandling: "start-of-activity-interrupts",
                turnCoverage: "audio-activity-and-all-video",
              },
            },
          },
        },
      },
    },
  },
}

Google Live API uses bidirectional audio and function calling over a WebSocket. OpenClaw adapts telephony/Meet bridge audio to Gemini's PCM Live API stream and keeps tool calls on the shared realtime voice contract. Leave temperature unset unless you need sampling changes; OpenClaw omits non-positive values because Google Live can return transcripts without audio for temperature: 0. Gemini API transcription is enabled without languageCodes; the current Google SDK rejects language-code hints on this API path.

Gemini 3.1 Live accepts conversational text through realtime input and uses sequential function calling. OpenClaw omits the older NON_BLOCKING, function response scheduling, and affective-dialog fields for this model. Prefer thinkingLevel; configured positive thinkingBudget values are mapped to the nearest supported level, while -1 leaves Google's default in place. See the Gemini Live capability comparison.

Control UI Talk supports Google Live browser sessions with constrained one-use tokens. In Video Talk, the browser sends bounded JPEG frames directly to Google Live at the provider's maximum of one frame per second. The describe_view function reports whether that camera stream is active. Camera frames do not pass through the Gateway. Backend-only realtime voice providers can also run through the generic Gateway relay transport, which keeps provider credentials on the Gateway.

For maintainer live verification, run OPENAI_API_KEY=... GEMINI_API_KEY=... node --import tsx scripts/dev/realtime-talk-live-smoke.ts. The smoke also covers OpenAI backend/WebRTC paths; the Google leg mints the same constrained Live API token shape used by Control UI Talk, opens the browser WebSocket endpoint, sends the initial setup payload plus a JPEG frame, and verifies a text response and describe_view function roundtrip.

고급 설정

Direct Gemini cache reuse

For direct Gemini API runs (`api: "google-generative-ai"`), OpenClaw
passes a configured `cachedContent` handle through to Gemini requests.

- Configure per-model or global params with either
  `cachedContent` or legacy `cached_content`
- Params from a more specific scope (model-level over global) always win.
  Within the same scope, if both keys are set, `cached_content` wins.
  Use only one key per scope to avoid surprises.
- Example value: `cachedContents/prebuilt-context`
- Gemini cache-hit usage is normalized into OpenClaw `cacheRead` from
  upstream `cachedContentTokenCount`

```json5
{
  agents: {
    defaults: {
      models: {
        "google/gemini-2.5-pro": {
          params: {
            cachedContent: "cachedContents/prebuilt-context",
          },
        },
      },
    },
  },
}
```

Gemini CLI usage notes

When using the `google-gemini-cli` OAuth provider, OpenClaw uses Gemini
CLI `stream-json` output by default and normalizes usage from the final
`stats` payload. Legacy `--output-format json` overrides still use the
JSON parser.

- Streamed reply text comes from assistant `message` events.
- For legacy JSON output, reply text comes from the CLI JSON `response` field.
- Usage falls back to `stats` when the CLI leaves `usage` empty.
- `stats.cached` is normalized into OpenClaw `cacheRead`.
- If `stats.input` is missing, OpenClaw derives input tokens from
  `stats.input_tokens - stats.cached`.

Environment and daemon setup

If the Gateway runs as a daemon (launchd/systemd), make sure `GEMINI_API_KEY`
is available to that process (for example, in `~/.openclaw/.env` or via
`env.shellEnv`).
