    OpenRouter and similar OpenAI-compatible gateways should be configured with `langchain_openai:ChatOpenAI` plus `base_url`. If you prefer a provider-specific environment variable name, point `api_key` at that variable explicitly (for example `api_key: $OPENROUTER_API_KEY`).
 
+   [API Route](https://www.api-route.com) is also available in the setup wizard. It saves your key as `API_ROUTE_API_KEY` and uses the Chat Completions endpoint above. Model availability depends on your key's group and permissions; check the authenticated `GET https://global.api-route.com/v1/models` catalog before replacing the model in `config.yaml`, and use its returned ID unchanged without an upstream provider prefix.
+
    The `write_file` tool's output-budget hint uses the active model's effective `max_tokens`. Missing or unusable limits, including YAML `.inf`, `-.inf`, `.nan`, and values too large for the character estimate, omit this hint without failing tool assembly; provider-specific model validation still applies.
 
    To route OpenAI models through `/v1/responses`, keep using `langchain_openai:ChatOpenAI` and set `use_responses_api: true` with `output_version: responses/v1`.

    OpenRouter 以及类似的 OpenAI 兼容网关，建议通过 `langchain_openai:ChatOpenAI` 配合 `base_url` 来配置。如果你更想用 provider 自己的环境变量名，也可以直接把 `api_key` 指向对应变量，例如 `api_key: $OPENROUTER_API_KEY`。
 
+   Setup Wizard 也支持 [API Route](https://www.api-route.com)，会将密钥保存为 `API_ROUTE_API_KEY`，并使用上面的 Chat Completions 端点。可用模型取决于密钥所属组别和权限；修改 `config.yaml` 中的模型前，请先查询需要认证的 `GET https://global.api-route.com/v1/models` 模型目录，并原样使用返回的模型 ID，不要添加上游 provider 前缀。
+
    如果要让 OpenAI 模型走 `/v1/responses`，继续使用 `langchain_openai:ChatOpenAI`，并设置 `use_responses_api: true` 和 `output_version: responses/v1`。
 
    如果某个模型的 provider 约定与 DeerFlow 通用的 thinking/effort 假设不同，可以为该模型声明 `reasoning:` 块（thinking 为 `unsupported`/`optional`/`required`、允许的 effort 取值及别名和默认值、payload 方言、推理历史要求）。Setup Wizard 内置的 Z.AI GLM-5.3-Flash 配置就使用了它：前台和后台调用都会保持 thinking 开启，effort 选择器只提供该模型自己的 `low`/`high`/`max` 档位。未声明该块的配置行为保持不变。具体格式与等价的手动配置见 `config.example.yaml`。
