Multi-model AI sounds simple from the outside.

Use more models.

Choose the best one.

Switch when needed.

In production, it is not that clean.

A product may use GPT for one workflow, Claude for another, Gemini for multimodal tasks, DeepSeek for cost-sensitive reasoning, Qwen or Kimi for coding and Chinese-language work, GLM for enterprise scenarios, and MiniMax or Doubao for other experiments.

At first, this feels flexible.

Then the product grows.

New features appear. More teams add prompts. Costs increase. Fallbacks are added. Some workflows need Chinese support. Some need long con
