A Developer's Checklist for Multi-Model LLM Routing
The article presents a developer's checklist for implementing multi-model LLM routing in production environments. It emphasizes the importance of abstraction, failover mechanisms, cost-aware routing, latency management, and observability. The author shares lessons learned from building AllToken, a system designed to simplify interactions across multiple AI providers.
- ▪A unified API schema is critical to avoid code branching by provider and to support seamless integration of new models.
- ▪Effective failover mechanisms should include health checks, circuit-breaking logic, and automatic retries without requiring application-level changes.
- ▪Cost and latency routing should be handled dynamically by the gateway based on request type and performance requirements.
- ▪Production gateways must provide granular observability, enabling attribution of cost, latency, and token usage to individual requests or users.
- ▪The checklist aims to prevent common pitfalls in multi-model LLM architectures, such as provider lock-in and operational complexity.

Posted on May 2 A Developer's Checklist for Multi-Model LLM Routing #ai #webdev #typescript #api I wrote an intro to AI API gateways on Medium last day. This is the practical follow-up: the checklist I wish I had before I built AllToken. Built AllToken for all developers. Many models, one decision. But that decision only makes sense if your routing layer doesn't become a nightmare to maintain.
