About Astasia Myers & Dan Bartus — Felicis Ventures - Routing the Future: Model Routing Will Decide Who Wins in AI Infrastructure - July 2025
An article by Astasia Myers and Dan Bartus of Felicis Ventures arguing that model routing will be the key winning category in AI infrastructure. It compares the AI era to the cloud era, highlighting the importance of the middle layer including inference, observability, testing/eval, and orchestration. The article predicts that model routing, which sits between applications and models, will enable a multi-model world by dynamically selecting the best model for each query, leveraging open-source and closed models, and handling multi-modal inputs.
Key Features
Routes queries across multiple AI models
Supports open-source (DeepSeek, Llama) and closed-source models
Enables cost and performance optimization
Handles multi-modal inputs (text, voice, video)
Facilitates portability across inference providers
Pros & Cons
Pros
- Enables a multi-model world with flexibility
- Allows applications to use best model for each task
- Reduces risk of model provider lock-in
- Optimizes performance and cost
Best For
Optimizing inference cost and speed for applicationsSelecting best model for different tasksManaging multi-model workflows in productionReducing dependency on single model provider
