Unverified流式响应基于HTTP的Server-Sent Events或WebSocket协议实现，可将首字节时间从数秒缩短至数百毫秒68% similarUnverifiedIn the callback mechanism, after the AI product server receives an HTTP POST request with the SheerID verification result, it must return an HTTP 200 status code within a limited time (typically 30 seconds) to indicate successful receipt.66% similarUnverifiedBecause LLM inference latency is typically on the order of several seconds, synchronous HTTP requests are prone to triggering gateway timeouts, and production deployments often need to introduce task queues (such as Celery or BullMQ) or WebSocket/SSE to maintain persistent connections.61% similarUnverifiedThe request-response cycle handled by a traditional API gateway usually completes within 50 to 200 milliseconds, whereas an LLM API often needs to keep the connection open for 30 to 120 seconds.60% similarVerifiedAPI calls to large models typically incur latency of hundreds of milliseconds to several seconds, and response times are unstable due to multiple factors such as network conditions and server load.60% similar
