Definition

Inference is the process of using a trained model to produce an output from new input.

01

Why Inference matters at work

Inference is where a trained model is used in a live workflow. Model size, hardware, input length, output length, batching, and tool use affect latency and cost, while the application still needs validation and monitoring around the model result.

02

A practical workplace example

Example

A team routes simple classification requests to a smaller model and complex contract analysis to a larger model, then evaluates quality and cost for both paths.

03

What teams should evaluate

  1. 01

    Compare quality, latency, context limits, reliability, and total operating cost on the same representative evaluation set.

  2. 02

    Record the model, tokenizer, configuration, and version used so a result can be reproduced and changes can be investigated.

  3. 03

    Review data rights, privacy requirements, security boundaries, and provider retention policies before sending workplace information.
