# ===================================
# 高级模型路由 YAML 模板（底层兼容 LiteLLM Router）
# ===================================
# 配套文档：docs/LLM_CONFIG_GUIDE.md 第 3.2 节
#
# 用法：
# 1. 复制此文件为 litellm_config.yaml
# 2. 在 .env 中设置 LITELLM_CONFIG=./litellm_config.yaml
# 3. 按需配置下面的 model_list
#
# 密钥引用格式：
#   api_key: "os.environ/ENV_VAR_NAME"  → 从环境变量读取，避免明文写入文件
#   api_key: "sk-xxxxxxxx"              → 直接写入（不推荐）
#
