Agentic labeling is an approach to auto-labeling where you interactively train a labeling agent in natural language, with no code, that is tuned to your specific dataset and labeling rules, then apply it to annotate data at scale. You teach the agent what you want, then let it label.
Agentic labeling reframes auto-labeling around a configurable agent rather than a fixed model. Instead of accepting a generic model's output, you train a labeling agent by describing what you want in plain language, and optionally giving a few visual examples, then reviewing the agent's sample outputs and refining your instructions until it matches your intent. Once it does, you apply the saved agent to label the rest of your data as a background job. The shift is from "run a model and correct it" to "teach an agent your labeling rules, then delegate."
Key takeaways
You train an agent interactively in natural language, no code, tuned to your data and rules.
It is a two-step pattern: teach the agent on a few examples, then apply it at scale.
It pairs the flexibility of prompting with reusability, the agent encodes your specific labeling standard.
How it works
Train: give a text prompt and optional visual prompts, a few example boxes, review the agent's sample labels, refine, and save the agent once it is right.
Apply: point the saved agent at a dataset or view and let it label as a background task.
Reuse: the same agent can re-label new data to the same standard, so your labeling rules become a portable asset.

Approach
How You Direct the Model
Reusable artifact?
Agentic labeling
Train an agent in natural language on your rules and examples
Yes, the saved agent re-labels new data to the same standard
Auto-labeling
Run a model, then correct its output
No, correction happens per batch
Zero-shot labeling
Prompt a model to apply its general knowledge as-is
No, the prompt is one-shot
Model-assisted labeling (a type of auto-labeling)
Accept, adjust, or reject the model's live suggestions as you label
No, guidance is per label
Pre-labeling (a type of auto-labeling)
Run a model in batch to pre-fill labels, then correct them
No, the draft is per batch
Why it matters
The real shift with agentic labeling is not automation, it is reusability. A prompt is one-shot, but a trained agent encodes your labeling standard as a reusable, auditable artifact, so consistency across millions of labels stops depending on a guidelines document and a rotating set of annotators. The hard part moves from drawing labels to specifying intent precisely, which is a skill, not a feature.
Frequently asked questions
What is the difference between agentic labeling and auto-labeling?
Auto-labeling runs a model and you correct it, agentic labeling has you train a reusable agent to your rules first, then apply it.
Do you need to code to use agentic labeling?
No, the agent is trained in natural language with optional visual examples.
How is it different from zero-shot labeling?
Zero-shot uses a model's general knowledge as-is, an agent is tuned to your specific dataset and labeling standard.
