UnverifiedMainstream open-source solutions for LLM Gateways include LiteLLM and PortKey, with core features covering multi-model routing and failover, rate limiting and circuit breaking, request retry, cost tracking, and load balancing.80% similarUnverifiedThe advantage of the LLM Gateway approach is that trace data can be obtained without modifying business code, while the disadvantage is that the gateway becomes a new critical path, introducing risks of latency, availability, and vendor lock-in.76% similarUnverifiedKong AI Gateway layers LLM-specific functionality on top of traditional API gateway capabilities, making it suitable for scenarios requiring enterprise-grade observability (logging, billing, and rate limiting).73% similarUnverifiedLLM agent gateways (LLM Proxies) are currently the mainstream solution for managing large model call governance.71% similarUnverifiedThe layered architecture of a preprocessing routing layer plus a main inference engine is commonly referred to in engineering as the Router-as-a-Service or LLM Gateway pattern.71% similar
