Running a trained AI model to produce output. Training teaches the model; inference is every time you use it. Inference is what costs money per token.
"Our inference bill doubled after we shipped the AI search."
Origin: Tech / AI / developer industry term.

Specifically in AI/ML: running a trained model to produce output, as opposed to training. "Inference cost" = the cost per API call.
"Inference is most of the GPU spend."
Origin: ML technical vocabulary; standard since the 2010s.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- test-time compute69%
Using more compute at inference time — via longer chain-of-thought, sampling, or verification — to boost model quality without retraining. The OpenAI o1 + Claude extended-thinking paradigm. You pay seconds to gain accuracy.
- distillation64%
Training a smaller, cheaper model to mimic the output of a larger one. "The 1B distillation of our 70B model runs fine on a laptop." Critical for shipping AI on devices, edge inference, and cost reduction. Trade-off: distilled models lose nuanced reasoning the parent could do.
- foundation model64%
An AI model trained on comprehensive data, enabling its application across various use cases such as chatbots and generative AI.
- test-time compute63%
The amount of computational power or processing time required for an artificial intelligence system to generate a result or perform a task after it has already been trained.
