## Definition

a computer or software system that runs an AI model to give you answers or predictions. You use it when you want the AI to actually do its job, like identifying a photo or translating text, after it has already been trained.

For teachers: a specialized server or software environment dedicated to executing a pre-trained machine learning model to generate outputs from new input data. It focuses on low-latency execution and resource management rather than the high-compute training phase.

## Examples

- The inference server processes your request and returns a translated sentence.
- After the team finished training the neural network, they deployed it to an inference server to handle live user traffic.
- Optimizing the inference server's throughput is critical for maintaining a responsive user experience in real-time applications like autonomous driving or instant speech recognition.

## Usage notes

- commonly used in technical contexts involving cloud computing, artificial intelligence, and software architecture.
- Teaching tip: contrast this with a 'training server'; explain that 'inference' is the stage where the AI 'reasons' or applies its knowledge to new data.
