| Google Gemini setup (AI Studio API key, Vertex AI, optional CLI runtime, and multimodal tools) | Google (Gemini) |
|
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_KEYorGOOGLE_API_KEY - API: Google Gemini API
- Managed-cloud provider:
google-vertexwith Google Cloud Application Default Credentials - Optional runtime:
agentRuntime.id: "google-gemini-cli"runs an explicitly configured model through the local Gemini CLI
Getting started
For most installations, use a Google AI Studio API key. Use google-vertex when
the Gateway already runs inside a managed Google Cloud environment.
<Steps>
<Step title="Get an API key">
Create a free key in [Google AI Studio](https://aistudio.google.com/apikey).
</Step>
<Step title="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"
```
</Step>
<Step title="Set a default model">
```json5
{
agents: {
defaults: {
model: { primary: "google/gemini-3.1-pro-preview" },
},
},
}
```
</Step>
<Step title="Verify the model is available">
```bash
openclaw models list --provider google
```
</Step>
</Steps>
<Tip>
`GEMINI_API_KEY` and `GOOGLE_API_KEY` are both accepted. Use whichever you already have configured.
</Tip>
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.
**Advanced use only:** run a canonical `google/*` model through an installed
Gemini CLI while keeping authentication on the supported AI Studio API-key
path.
OpenClaw does not offer new Gemini CLI OAuth or Antigravity OAuth setup.
[Google ended consumer Gemini CLI Login with Google access on June 18, 2026](https://developers.google.com/gemini-code-assist/docs/deprecations/code-assist-individuals),
and the [Antigravity terms](https://antigravity.google/terms) prohibit
third-party tools from accessing the service through Antigravity OAuth. Use
an AI Studio API key or Vertex AI instead.
<Steps>
<Step title="Configure Google AI Studio">
Complete the API-key setup in the first tab. OpenClaw must have a usable
`google` API-key profile before the CLI runtime can be selected.
</Step>
<Step title="Install 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.
</Step>
<Step title="Select the CLI runtime">
Keep the canonical Google model ref and opt that model into the CLI
runtime:
```json5
{
agents: {
defaults: {
model: { primary: "google/gemini-3.1-pro-preview" },
models: {
"google/gemini-3.1-pro-preview": {
agentRuntime: { id: "google-gemini-cli" },
},
},
},
},
}
```
</Step>
</Steps>
- Runtime: `google-gemini-cli`
- Auth: selected Google AI Studio API-key profile
- Model refs: canonical `google/*`
Existing valid Gemini CLI OAuth profiles remain executable for compatibility,
but OpenClaw cannot create or repair them. If one breaks, replace it with a
Google AI Studio API-key profile.
`google-gemini-cli/*` refs remain legacy compatibility aliases. New configs
should use `google/*` model refs plus the explicit runtime selection above.
`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.

Web search
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.
/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.
Image generation
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, andresolution
To use Google as the default image provider:
{
agents: {
defaults: {
imageGenerationModel: {
primary: "google/gemini-3.1-flash-image",
},
},
},
}
Video generation
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) andresolution(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",
},
},
},
}
Music generation
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:
lyricsandinstrumental - Output format:
mp3by default, pluswavongoogle/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",
},
},
},
}
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, orGOOGLE_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]]
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",
},
},
},
},
},
},
},
}
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.
Advanced configuration
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",
},
},
},
},
},
}
```
The optional `google-gemini-cli` runtime 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`.
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`).
