ModelChain: Measurable LLM Router with Adaptive Model Selection, Real-Time Scoring, Budget Guards and Failover for Node.js, Edge and Browser
ModelChain is a new open-source router designed to dynamically select the most efficient LLM for a given task. It supports multiple providers like OpenAI, Anthropic, and Gemini, and uses adaptive strategies based on real-time cost, latency, and quality scoring. The tool also includes features for budget control, automatic failover, and normalized responses for streaming and tool calling across different models. AI
