Manifest scrapped its LLM router – argues single models are better
Manifest removed its LLM router that automatically selected models based on task complexity. After four months with 7000 cloud users, they saw mixed results and concluded that cost savings were outweighed by problems with unpredictability, loss of behavioral consistency, and that caching is more cost-effective than routing.
WHY IT MATTERS
The case challenges a growing trend around AI model routing and shows that application focus on single models with cache optimization may be better than dynamic model selection for most use cases.
