LinkAI - CowAgent

A single linkai_api_key gives you access to all capabilities of mainstream providers such as OpenAI, Claude, Gemini, DeepSeek, MiniMax, Qwen, Kimi, and Doubao.

All capabilities below can be configured in one place via the “Model Management” page in the Web Console, with no need to manually edit the configuration file.

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, qwen3.7-plus, doubao-seed-2-1-pro-260628, kimi-k2.6, claude-sonnet-5, gemini-3.1-flash-lite-preview, etc.

Image Generation

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

Model ID	Alias
`gpt-image-2`	OpenAI
`gemini-3.1-flash-image-preview`	Nano Banana 2
`gemini-3-pro-image-preview`	Nano Banana Pro
`seedream-5.0-lite`	ByteDance Doubao Seedream

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"
}

`text_to_voice_model`	Engine
`tts-1`	OpenAI · Multi-language (voices like `alloy` / `nova` / `echo`, etc.)
`doubao`	ByteDance Doubao · Rich Chinese voices
`baidu`	Baidu · Chinese broadcaster voices

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.
