Switch between AI models dynamically to optimize costs and performance. Use when the user says mode commands like "eco mode", "balanced mode", "smart mode", or "max mode", or when they want to check their current mode with "/modes status" or configure modes with "/modes setup".

动态切换AI模型以优化成本和性能。当用户使用模式指令如“节能模式”、“均衡模式”、“智能模式”或“极致模式”，或通过“/modes status”查询当前模式、通过“/modes setup”配置模式时生效。
