Node.js API unifies LLM calls with strict schema and eval suite

A developer outlines a strategy for managing multiple large language models like OpenAI, Claude, and Gemini within a Node.js application. The approach involves creating a unified, internal text classification API that abstracts away the complexities of individual model providers. This API would use a single key and enforce a strict JSON output contract, ensuring consistency in labels, confidence scores, and refusal handling across different models. The system emphasizes the importance of an evaluation suite to measure and reverse route changes, making model routing a defensible and observable process rather than guesswork. AI

    Schema Evals for a One-Key Node.js Text Classification API

    <p><strong>Short answer:</strong> replace separate provider clients with one scoped classification API key and a strict JSON contract, keep chat completion model routing behind aliases, and require every route change to pass the same eval suite.</p> <p>The deciding trade-off is c…
