Zero-Shot Classification with LLMs

No training required

Traditional classifiers need labeled examples. An LLM can classify into arbitrary labels you define, right in the prompt.

Classify the ticket into one of: Billing, Bug, Feature, Other.
Respond with only the label.

Ticket: "The app crashes when I export to PDF."

When to use it

Great for prototyping, low-volume tasks, or when labels change often. For high-volume, latency-sensitive classification, distill the LLM's labels into a small fast model later. Add a few examples (few-shot) if zero-shot accuracy isn't enough.
