Error Cause (Original JSON)

{
  "message": "Claude Code returned an error result: API Error: 400 {\"error\":{\"type\":\"<nil>\",\"message\":\"\\\"***.***.enabled\\\" is not supported for this model. Use \\\"***.***.adaptive\\\" and \\\"output_config.effort\\\" to control thinking behavior.\"},\"type\":\"error\"}",
  "type": "stream_error",
  "code": "stream_processing_failed"
}

Environment Information

• Platform: Windows
• Installation Path: F:\Tool/CherryStudio/
• Provider: Claude Code (Anthropic API compatibility mode)

Steps to Reproduce

1. Configure Claude Code as AI Provider in Cherry Studio
2. Trigger the error when calling the model using Agent functionality

Expected Behavior

The model should be called normally and return a response.

Actual Behavior

The API returns a 400 error, stating that the "thinking.enabled" parameter is not supported by this model, and suggesting to use "thinking.adaptive" and "output_config.effort" to control thinking behavior. It is suspected that Cherry Studio used the incompatible thinking.enabled field when constructing the request parameters.

Remarks

The API explicitly indicates that thinking.adaptive + output_config.effort should be used instead of thinking.enabled to control the model's thinking/reasoning behavior.

错误原因（原始 JSON）

{
  "message": "Claude Code returned an error result: API Error: 400 {\"error\":{\"type\":\"<nil>\",\"message\":\"\\\"***.***.enabled\\\" is not supported for this model. Use \\\"***.***.adaptive\\\" and \\\"output_config.effort\\\" to control thinking behavior.\"},\"type\":\"error\"}",
  "type": "stream_error",
  "code": "stream_processing_failed"
}

环境信息

• 平台: Windows
• 安装路径: F:\Tool/CherryStudio/
• Provider: Claude Code (Anthropic API 兼容模式)

复现步骤

1. 使用 Cherry Studio 配置 Claude Code 作为 AI Provider
2. 使用 Agent 功能调用模型时触发错误

预期行为

正常调用模型并返回响应。

实际行为

API 返回 400 错误，提示 "thinking.enabled" 参数不被该模型支持，建议使用 "thinking.adaptive" 和 "output_config.effort" 来控制思考行为。推测是 Cherry Studio 在构造请求参数时使用了不兼容的 thinking.enabled 字段。

备注

API 明确指出应使用 thinking.adaptive + output_config.effort 替代 thinking.enabled 来控制模型的 thinking/reasoning 行为。
