## Definition

to use a trained AI model to process new data and get a result, like a prediction or a translation.

For teachers: to execute a trained machine learning model on new input data to generate a prediction or output. This represents the operational phase of AI, distinct from the training phase.

## Examples

- The app needs to run inference on your photo to identify the plant.
- Once the neural network is fully trained, we can run inference on the live data stream to detect errors in real time.
- Optimizing the hardware allows the system to run inference with significantly lower latency, which is critical for autonomous vehicle safety.

## Usage notes

- typically used in technical contexts involving artificial intelligence and machine learning.
- Teaching tip: contrast this with 'training a model'; training is the learning phase, while 'running inference' is the application of that learning to new information.
