Why Multi-Model Smart Routing? # In 2026, the AI model ecosystem has matured dramatically. OpenAI shipped GPT-5 and GPT-5-mini, Anthropic launched Claude Opus 4 and Claude Sonnet 4, Google’s Gemini 2.5 Pro is widely available, and Chinese models like DeepSeek-V4, Qwen3-235B, and GLM-5 are evolving at breakneck speed.
As a developer, you probably face these pain points:
Multiple providers, multiple API Keys — management overhead is real A model hits rate limits or goes down and your service breaks Different tasks suit different models, but manual switching is tedious Costs spiral when you use expensive models for simple tasks The solution: XiDao API Gateway (global.xidao.online)
Introduction # In 2026, Anthropic released Claude 4.7 — a landmark model that pushes the boundaries of reasoning, code generation, multimodal understanding, and long-context processing. For developers, knowing how to efficiently and reliably integrate the Claude 4.7 API into production systems is now an essential skill.
This guide walks you through everything: from your first API call to production-grade deployment, covering the latest API changes, pricing structure, and battle-tested best practices.
