What Is Low-Latency AI Inference?
Low-latency AI inference refers to the ability to process AI model requests and return results in minimal time, often measured in milliseconds or even microseconds. This is critical for real-time applications such as conversational AI, autonomous systems, trading platforms, and interactive customer experiences. Low-latency inference APIs leverage specialized hardware accelerators, optimized software frameworks, and intelligent resource management to minimize the time between sending a request and receiving a response. This technique is widely used by developers, data scientists, and enterprises to create responsive AI solutions for chatbots, recommendation engines, real-time analytics, and more.
