Image Understanding

Once configured, the Agent's Vision tool automatically calls multimodal models via the gateway, with no extra setup required. To manually specify a Vision model:

{
  "tools": {
    "vision": {
      "model": "gpt-5.4-mini"
    }
  }
}

Available models: gpt-4.1-mini, gpt-5.4-mini, qwen3.6-plus, doubao-seed-2-0-pro-260215, kimi-k2.6, claude-sonnet-4-6, gemini-3.1-flash-lite-preview, etc.

Image Generation

{
  "skills": {
    "image-generation": {
      "model": "gpt-image-2"
    }
  }
}

Speech-to-Text (ASR)

{
  "voice_to_text": "linkai"
}

ASR uses Whisper by default; credentials are automatically reused from linkai_api_key.

Text-to-Speech (TTS)

The TTS gateway supports multiple underlying engines. The engine is selected by text_to_voice_model, and the available voices change with the engine.

{
  "text_to_voice": "linkai",
  "text_to_voice_model": "doubao",
  "tts_voice_id": "BV001_streaming"
}

Voices differ by engine; we recommend selecting them visually in the Web Console under "Model Management → Text-to-Speech".

Embedding

{
  "embedding_provider": "linkai",
  "embedding_model": "text-embedding-3-small"
}

The default model is text-embedding-3-small (OpenAI-compatible). After changing the embedding, run /memory rebuild-index to rebuild the index.
