CrewAI is a Python framework for building multi-agent AI systems. You define agents with specific roles, goals, and tools, then organize them into crews that collaborate on complex tasks. It simplifies building AI teams that work together.

When should I use CrewAI vs LangGraph?

CrewAI is better for role-based multi-agent collaboration with less code. LangGraph offers more control over state and flow. CrewAI is faster to prototype; LangGraph is better for complex, custom agent architectures. CrewAI is higher-level abstraction.

What can I build with CrewAI?

Common use cases: automated research teams, content creation pipelines, data analysis crews, customer support triage, code review teams, and business process automation. Any task that benefits from multiple specialized agents working together.

How do I define agents in CrewAI?

Agents are defined with: role (job title), goal (objective), backstory (context), and tools (capabilities). Example: Agent(role="Research Analyst", goal="Find and analyze market data", tools=[search_tool, calculator]). The backstory helps the LLM understand context.

What is a CrewAI task?

Tasks are specific assignments for agents. Each task has: description (what to do), expected_output (format of result), and assigned agent. Tasks can have dependencies—agent B waits for agent A's output. The crew orchestrates task execution.

Does CrewAI support memory?

Yes. CrewAI supports memory at agent and crew levels. Short-term memory for current task context, long-term memory for past interactions, and entity memory for tracking people/concepts. Memory helps agents learn and maintain context across tasks.

What LLMs work with CrewAI?

CrewAI works with any LangChain-supported LLM: OpenAI, Anthropic, local models via Ollama, and more. Different agents in the same crew can use different models. Use powerful models for complex reasoning, cheaper ones for simple tasks.
