Event-driven orchestration\n\nFor complex workflows with conditional logic, use Flows:\n\n```python\nfrom crewai.flow.flow import Flow, listen, start, router\nfrom pydantic import BaseModel\n\nclass MyState(BaseModel):\n    confidence: float = 0.0\n\nclass MyFlow(Flow[MyState]):\n    @start()\n    def gather_data(self):\n        return {\"data\": \"collected\"}\n\n    @listen(gather_data)\n    def analyze(self, data):\n        self.state.confidence = 0.85\n        return analysis_crew.kickoff(inputs=data)\n\n    @router(analyze)\n    def decide(self):\n        return \"high\" if self.state.confidence > 0.8 else \"low\"\n\n    @listen(\"high\")\n    def generate_report(self):\n        return report_crew.kickoff()\n\n# Run flow\nflow = MyFlow()\nresult = flow.kickoff()\n```\n\nSee [Flows Guide](references\u002Fflows.md) for complete documentation.\n\n## Memory system\n\n```python\n# Enable all memory types\ncrew = Crew(\n    agents=[researcher],\n    tasks=[research_task],\n    memory=True,           # Enable memory\n    embedder={             # Custom embeddings\n        \"provider\": \"openai\",\n        \"config\": {\"model\": \"text-embedding-3-small\"}\n    }\n)\n```\n\n**Memory types:** Short-term (ChromaDB), Long-term (SQLite), Entity (ChromaDB)\n\n## LLM providers\n\n```python\nfrom crewai import LLM\n\nllm = LLM(model=\"gpt-4o\")                              # OpenAI (default)\nllm = LLM(model=\"claude-sonnet-4-5-20250929\")                       # Anthropic\nllm = LLM(model=\"ollama\u002Fllama3.1\", base_url=\"http:\u002F\u002Flocalhost:11434\")  # Local\nllm = LLM(model=\"azure\u002Fgpt-4o\", base_url=\"https:\u002F\u002F...\")              # Azure\n\nagent = Agent(role=\"Analyst\", goal=\"Analyze data\", llm=llm)\n```\n\n## CrewAI vs alternatives\n\n| Feature | CrewAI | LangChain | LangGraph |\n|---------|--------|-----------|-----------|\n| **Best for** | Multi-agent teams | General LLM apps | Stateful workflows |\n| **Learning curve** | Low | Medium | Higher |\n| **Agent paradigm** | Role-based | Tool-based | Graph-based |\n| **Memory** | Built-in | Plugin-based | Custom |\n\n## Best practices\n\n1. **Clear roles** - Each agent should have a distinct specialty\n2. **YAML config** - Better organization for larger projects\n3. **Enable memory** - Improves context across tasks\n4. **Set max_iter** - Prevent infinite loops (default 15)\n5. **Limit tools** - 3-5 tools per agent max\n6. **Rate limiting** - Set max_rpm to avoid API limits\n\n## Common issues\n\n**Agent stuck in loop:**\n```python\nagent = Agent(\n    role=\"...\",\n    max_iter=10,           # Limit iterations\n    max_rpm=5              # Rate limit\n)\n```\n\n**Task not using context:**\n```python\ntask2 = Task(\n    description=\"...\",\n    context=[task1],       # Explicitly pass context\n    agent=writer\n)\n```\n\n**Memory errors:**\n```python\n# Use environment variable for storage\nimport os\nos.environ[\"CREWAI_STORAGE_DIR\"] = \".\u002Fmy_storage\"\n```\n\n## References\n\n- **[Flows Guide](references\u002Fflows.md)** -

self.state.confidence > 0.8 else \"low\"\n\n    @listen(\"high\")\n    def generate_report(self):\n        return report_crew.kickoff()\n\n# Run flow\nflow = MyFlow()\nresult = flow.kickoff()\n```\n\nSee [Flows Guide](references\u002Fflows.md) for complete documentation.\n\n## Memory system\n\n```python\n# Enable all memory types\ncrew = Crew(\n    agents=[researcher],\n    tasks=[research_task],\n    memory=True,           # Enable memory\n    embedder={             # Custom embeddings\n        \"provider\": \"openai\",\n        \"config\": {\"model\": \"text-embedding-3-small\"}\n    }\n)\n```\n\n**Memory types:** Short-term (ChromaDB), Long-term (SQLite), Entity (ChromaDB)\n\n## LLM providers\n\n```python\nfrom crewai import LLM\n\nllm = LLM(model=\"gpt-4o\")                              # OpenAI (default)\nllm = LLM(model=\"claude-sonnet-4-5-20250929\")                       # Anthropic\nllm = LLM(model=\"ollama\u002Fllama3.1\", base_url=\"http:\u002F\u002Flocalhost:11434\")  # Local\nllm = LLM(model=\"azure\u002Fgpt-4o\", base_url=\"https:\u002F\u002F...\")              # Azure\n\nagent = Agent(role=\"Analyst\", goal=\"Analyze data\", llm=llm)\n```\n\n## CrewAI vs alternatives\n\n| Feature | CrewAI | LangChain | LangGraph |\n|---------|--------|-----------|-----------|\n| **Best for** | Multi-agent teams | General LLM apps | Stateful workflows |\n| **Learning curve** | Low | Medium | Higher |\n| **Agent paradigm** | Role-based | Tool-based | Graph-based |\n| **Memory** | Built-in | Plugin-based | Custom |\n\n## Best practices\n\n1. **Clear roles** - Each agent should have a distinct specialty\n2. **YAML config** - Better organization for larger projects\n3. **Enable memory** - Improves context across tasks\n4. **Set max_iter** - Prevent infinite loops (default 15)\n5. **Limit tools** - 3-5 tools per agent max\n6. **Rate limiting** - Set max_rpm to avoid API limits\n\n## Common issues\n\n**Agent stuck in loop:**\n```python\nagent = Agent(\n    role=\"...\",\n    max_iter=10,           # Limit iterations\n    max_rpm=5              # Rate limit\n)\n```\n\n**Task not using context:**\n```python\ntask2 = Task(\n    description=\"...\",\n    context=[task1],       # Explicitly pass context\n    agent=writer\n)\n```\n\n**Memory errors:**\n```python\n# Use environment variable for storage\nimport os\nos.environ[\"CREWAI_STORAGE_DIR\"] = \".\u002Fmy_storage\"\n```\n\n## References\n\n- **[Flows Guide](references\u002Fflows.md)** - Event-driven workflows, state
