Common AI Operators

Choosing the right operator

The common-ai provider ships four operators (and matching @task decorators). Use this table to pick the one that fits your use case:

.. list-table:: :header-rows: 1 :widths: 40 30 30

• • Need
  • Operator
  • Decorator
• • Single prompt → text or structured output
  • :class:~airflow.providers.common.ai.operators.llm.LLMOperator
  • @task.llm
• • LLM picks which downstream task runs
  • :class:~airflow.providers.common.ai.operators.llm_branch.LLMBranchOperator
  • @task.llm_branch
• • Natural-language → SQL generation (no execution)
  • :class:~airflow.providers.common.ai.operators.llm_sql.LLMSQLQueryOperator
  • @task.llm_sql
• • Multi-turn reasoning with tools (DB queries, API calls, etc.)
  • :class:~airflow.providers.common.ai.operators.agent.AgentOperator
  • @task.agent

LLMOperator / @task.llm — stateless, single-turn calls. Use this for classification, summarization, extraction, or any prompt that produces one response. Supports structured output via a response_format Pydantic model.

AgentOperator / @task.agent — multi-turn tool-calling loop. The model decides which tools to invoke and when to stop. Use this when the LLM needs to take actions (query databases, call APIs, read files) to produce its answer. You configure available tools through toolsets.

AgentOperator works without toolsets — pydantic-ai supports tool-less agents for multi-turn reasoning — but if you don't need tools, LLMOperator is simpler and more explicit.
