When using the Custom LLM approach, you must host the WebSocket server yourself on the call's critical path; the server should be as close to Retell's region as possible to control additional latency, and you should test it in practice before deployment.

UnverifiedIf push-level real-time behavior is needed, it should instead be driven by the provider's Webhook or push notifications, but this usually requires additional server-side configuration.69% similarVerifiedThe WebSocket protocol establishes a persistent bidirectional communication channel through which the server can proactively push data to the client, with latency as low as milliseconds.68% similarUnverified跨节点LLM推理的可行性根本上受网络互连延迟约束：在标准以太网上运行跨节点张量并行会引入巨大同步延迟，只有具备低延迟RDMA或高速专用链路才具备实用价值。68% 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.67% similarUnverifiedIf an LLM gateway requires installing an SDK, rewriting client code, or a mandatory registration process, it should be placed at the end of the list unless it stands out in other respects.67% similar
