deepseek-peak-valley-router

DeepSeek V4 API has introduced a peak and valley pricing strategy where peak hours are twice as expensive as off-peak hours, creating a challenge for cost optimization. To balance service quality with budget constraints, this plugin acts as an intelligent traffic controller. It automatically detects whether the current time—based on your configured reference time zone (defaulting to Beijing time)—is a high-cost peak or a low-cost off-peak period. During peak hours, the plugin seamlessly routes requests to the cost-effective deepseek-v4-flash model; conversely, during off-peak hours, it switches to the high-performance deepseek-v4-pro model, ensuring you get the best output quality for a lower price. Crucially, it prioritizes your explicit choices, ensuring you never lose control over your model selection unless you intentionally change it. This makes it an essential tool for developers and users looking to reduce API expenses without sacrificing performance.
