+    已生成完整的 qwen3.7-max 配置SQL。以下是配置方案：
+    
+    模型摘要
+    - 模型名称: 千问3.7-Max
+    - API model: qwen3.7-max (严格按API文档填写)
+    - 分类: text2text (文生文)
+    - 供应商: 阿里百炼 (ali-qwen)
+    - 接口: OpenAI兼容 /chat/completions，同步流式
+    
+    复用vs新建
+    - upapp: 复用 ali-qwen (阿里百炼)
+    - upappkey: 复用 gCMl-BnrTrfoqWAEPPoH8 (API Key已配置)
+    - uapi: 复用 t2t (BY2cA4RD_axNxTG4m9Coa)
+    - uapiio: 复用 Is8l4TGkcZcqFSjbbeIK2 (文本会话)
+    - llm: 新建
+    - llm_api_map: 新建
+    - pricing_program: 新建
+    - pricing_program_timing: 新建

+    sql
+    SELECT id, name, model, upappid, apiname FROM llm WHERE model = 'qwen3.7-max';
+    SELECT id, llmid, llmcatelogid, apiname, ppid FROM llm_api_map WHERE llmid = 'Jt26VKlUFsJxABuVLauBc';
+    SELECT id, name FROM pricing_program WHERE id = '0B-JNSUEelsY5TQ_Sawa7';
+    
+    
+    ppid三处一致
+    - pricing_program.id = 0B-JNSUEelsY5TQ_Sawa7
+    - pricing_program_timing.ppid = 0B-JNSUEelsY5TQ_Sawa7
+    - llm_api_map.ppid = 0B-JNSUEelsY5TQ_Sawa7
+    
+    注意事项
+    1. 定价参考qwen3.6-plus的阶梯式计费模式，具体价格需根据百炼官方定价调整
+    2. qwen3.7-max使用已有的t2t uapi，OpenAI兼容接口
+    3. 如果qwen3.7-max有特殊的推理模式（如思考/非思考切换），可能需要额外的配置
+    4. 之前提到的 startReasoning is not defined 前端报错问题需要单独排查，可能与harnessed_reasoning的bricks前端代码有关
