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
