Qianfan is Baidu's MaaS platform, providing a unified API that routes requests to many models behind a single endpoint and API key. It is OpenAI-compatible, so most OpenAI SDKs work by switching the base URL.

Property Value
Provider qianfan
Auth QIANFAN_API_KEY
API OpenAI-compatible
Base URL https://qianfan.baidubce.com/v2

Getting started

Create a Baidu Cloud account

Sign up or log in at the [Qianfan Console](https://console.bce.baidu.com/qianfan/ais/console/apiKey) and ensure you have Qianfan API access enabled.

Generate an API key

Create a new application or select an existing one, then generate an API key. The key format is `bce-v3/ALTAK-...`.

Run onboarding

```bash
genesis onboard --auth-choice qianfan-api-key
```

Verify the model is available

```bash
genesis models list --provider qianfan
```

Built-in catalog

Model ref Input Context Max output Reasoning Notes
qianfan/deepseek-v3.2 text 98,304 32,768 Yes Default model
qianfan/ernie-5.0-thinking-preview text, image 119,000 64,000 Yes Multimodal
The default bundled model ref is `qianfan/deepseek-v3.2`. You only need to override `models.providers.qianfan` when you need a custom base URL or model metadata.

Config example

{
  env: { QIANFAN_API_KEY: "bce-v3/ALTAK-..." },
  agents: {
    defaults: {
      model: { primary: "qianfan/deepseek-v3.2" },
      models: {
        "qianfan/deepseek-v3.2": { alias: "QIANFAN" },
      },
    },
  },
  models: {
    providers: {
      qianfan: {
        baseUrl: "https://qianfan.baidubce.com/v2",
        api: "openai-completions",
        models: [
          {
            id: "deepseek-v3.2",
            name: "DEEPSEEK V3.2",
            reasoning: true,
            input: ["text"],
            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
            contextWindow: 98304,
            maxTokens: 32768,
          },
          {
            id: "ernie-5.0-thinking-preview",
            name: "ERNIE-5.0-Thinking-Preview",
            reasoning: true,
            input: ["text", "image"],
            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
            contextWindow: 119000,
            maxTokens: 64000,
          },
        ],
      },
    },
  },
}

Transport and compatibility

Qianfan runs through the OpenAI-compatible transport path, not native OpenAI request shaping. This means standard OpenAI SDK features work, but provider-specific parameters may not be forwarded.

Catalog and overrides

The bundled catalog currently includes `deepseek-v3.2` and `ernie-5.0-thinking-preview`. Add or override `models.providers.qianfan` only when you need a custom base URL or model metadata.

<div class="callout note">
Model refs use the `qianfan/` prefix (for example `qianfan/deepseek-v3.2`).
</div>

Troubleshooting

- Ensure your API key starts with `bce-v3/ALTAK-` and has Qianfan API access enabled in the Baidu Cloud console.
- If models are not listed, confirm your account has the Qianfan service activated.
- The default base URL is `https://qianfan.baidubce.com/v2`. Only change it if you use a custom endpoint or proxy.
