xAI

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

```bash
openclaw config set tools.web.search.provider grok
```

- Default video model: `xai/grok-imagine-video`
- Modes: text-to-video, image-to-video, reference-image generation, remote
  video edit, and remote video extension
- Aspect ratios: `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `3:2`, `2:3`
- Resolutions: `480P`, `720P`
- Duration: 1-15 seconds for generation/image-to-video, 1-10 seconds when
  using `reference_image` roles, 2-10 seconds for extension
- Reference-image generation: set `imageRoles` to `reference_image` for
  every supplied image; xAI accepts up to 7 such images

<Warning>
Local video buffers are not accepted. Use remote `http(s)` URLs for
video edit/extend inputs. Image-to-video accepts local image buffers because
OpenClaw can encode those as data URLs for xAI.
</Warning>

To use xAI as the default video provider:

```json5
{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "xai/grok-imagine-video",
      },
    },
  },
}
```

<Note>
See [Video Generation](/tools/video-generation) for shared tool parameters,
provider selection, and failover behavior.
</Note>

- Default image model: `xai/grok-imagine-image`
- Additional model: `xai/grok-imagine-image-pro`
- Modes: text-to-image and reference-image edit
- Reference inputs: one `image` or up to five `images`
- Aspect ratios: `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `2:3`, `3:2`
- Resolutions: `1K`, `2K`
- Count: up to 4 images

OpenClaw asks xAI for `b64_json` image responses so generated media can be
stored and delivered through the normal channel attachment path. Local
reference images are converted to data URLs; remote `http(s)` references are
passed through.

To use xAI as the default image provider:

```json5
{
  agents: {
    defaults: {
      imageGenerationModel: {
        primary: "xai/grok-imagine-image",
      },
    },
  },
}
```

<Note>
xAI also documents `quality`, `mask`, `user`, and additional native ratios
such as `1:2`, `2:1`, `9:20`, and `20:9`. OpenClaw forwards only the
shared cross-provider image controls today; unsupported native-only knobs
are intentionally not exposed through `image_generate`.
</Note>

- Voices: `eve`, `ara`, `rex`, `sal`, `leo`, `una`
- Default voice: `eve`
- Formats: `mp3`, `wav`, `pcm`, `mulaw`, `alaw`
- Language: BCP-47 code or `auto`
- Speed: provider-native speed override
- Native Opus voice-note format is not supported

To use xAI as the default TTS provider:

```json5
{
  messages: {
    tts: {
      provider: "xai",
      providers: {
        xai: {
          voiceId: "eve",
        },
      },
    },
  },
}
```

<Note>
OpenClaw uses xAI's batch `/v1/tts` endpoint. xAI also offers streaming TTS
over WebSocket, but the OpenClaw speech provider contract currently expects
a complete audio buffer before reply delivery.
</Note>

- Default model: `grok-stt`
- Endpoint: xAI REST `/v1/stt`
- Input path: multipart audio file upload
- Supported by OpenClaw wherever inbound audio transcription uses
  `tools.media.audio`, including Discord voice-channel segments and
  channel audio attachments

To force xAI for inbound audio transcription:

```json5
{
  tools: {
    media: {
      audio: {
        models: [
          {
            type: "provider",
            provider: "xai",
            model: "grok-stt",
          },
        ],
      },
    },
  },
}
```

Language can be supplied through the shared audio media config or per-call
transcription request. Prompt hints are accepted by the shared OpenClaw
surface, but the xAI REST STT integration only forwards file, model, and
language because those map cleanly to the current public xAI endpoint.

- Endpoint: xAI WebSocket `wss://api.x.ai/v1/stt`
- Default encoding: `mulaw`
- Default sample rate: `8000`
- Default endpointing: `800ms`
- Interim transcripts: enabled by default

Voice Call's Twilio media stream sends G.711 µ-law audio frames, so the
xAI provider can forward those frames directly without transcoding:

```json5
{
  plugins: {
    entries: {
      "voice-call": {
        config: {
          streaming: {
            enabled: true,
            provider: "xai",
            providers: {
              xai: {
                apiKey: "${XAI_API_KEY}",
                endpointingMs: 800,
                language: "en",
              },
            },
          },
        },
      },
    },
  },
}
```

Provider-owned config lives under
`plugins.entries.voice-call.config.streaming.providers.xai`. Supported
keys are `apiKey`, `baseUrl`, `sampleRate`, `encoding` (`pcm`, `mulaw`, or
`alaw`), `interimResults`, `endpointingMs`, and `language`.

<Note>
This streaming provider is for Voice Call's realtime transcription path.
Discord voice currently records short segments and uses the batch
`tools.media.audio` transcription path instead.
