From Four APIs to One: How Intelligent Routing Cut LLM Costs 35%

Managing multiple specialized AI models is increasingly necessary—DeepSeek for reasoning, Kimi for document processing, MiniMax for multimodal tasks, and Qwen for heavy lifting—but coordination creates operational overhead. This article demonstrates how intelligent routing through unified gateways like NovaStack can dramatically reduce costs (35% in practice) while improving performance by matching tasks to optimal models. As the AI model landscape fragments, gateway-based orchestration is becoming critical infrastructure for enterprises seeking cost efficiency and resilience in production AI systems.
