Deployment Platforms
Trend: Single agents → collaborative agent teams
```python
from crewai import Agent, Task, Crew
researcher = Agent(
role="Researcher",
goal="Find accurate information",
backstory="Expert researcher with attention to detail"
)
analyst = Agent(
role="Analyst",
goal="Analyze data and draw insights",
backstory="Data analyst with statistical expertise"
)
writer = Agent(
role="Writer",
goal="Create compelling content",
backstory="Professional writer with journalism background"
)
crew = Crew(
agents=[researcher, analyst, writer],
tasks=[research_task, analysis_task, writing_task],
process="sequential" # or "hierarchical"
)
result = crew.kickoff()
```
Adoption: 45% of enterprise deployments use multi-agent architectures (up from 8% in 2024).
Benefits:
Evolution: Static RAG → Dynamic agentic RAG
```python
class AgenticRAG:
async def answer_question(self, question: str) -> str:
# Agent decides retrieval strategy
strategy = await self.agent.plan_retrieval(question)
if strategy == "semantic_search":
docs = await self.vector_db.search(question)
elif strategy == "sql_query":
docs = await self.sql_db.query(self.agent.generate_sql(question))
elif strategy == "api_call":
docs = await self.api.fetch(self.agent.generate_api_params(question))
else: # multi_source
docs = await self.multi_source_retrieval(question)
# Agent synthesizes answer
return await self.agent.synthesize(question, docs)
```
Key Innovation: Agents dynamically choose retrieval methods based on query type.
Adoption: 62% of RAG systems now use agentic approaches.
Trend: Model routing based on task complexity
```typescript
class CostOptimizedAgent {
async execute(task: Task): Promise
const complexity = await this.analyzeComplexity(task)
// Route to appropriate model
const model = this.selectModel(complexity)
return await model.complete(task)
}
private selectModel(complexity: number): Model {
if (complexity < 0.3) {
return new Model("haiku", { cost: 0.00025 }) // 90% of tasks
} else if (complexity < 0.7) {
return new Model("sonnet", {0.003 }) // 8% of tasks
} else {
return new Model("opus", { cost: 0.015 }) // 2% of tasks
}
}
}
```
Impact: Average cost reduction of 65% compared to using premium models for all tasks.
Adoption: 73% of production systems implement model routing.
Trend: General-purpose agents → domain-specific agents
Examples:
Medical Agents
Legal Agents
Financial Agents
Code Agents
Trend: Fully autonomous → supervised autonomy
```python
class SupervisedAgent:
async def execute(self, task: Task) -> Result:
# Agent proposes action
proposed_action = await self.plan_action(task)
# Risk assessment
risk = self.assess_risk(proposed_action)
if risk > self.risk_threshold:
# Request human approval
approved = await self.request_human_approval(proposed_action)
if not approved:
return self.escalate_to_human(task)
# Execute with monitoring
result = await self.execute_with_monitoring(proposed_action)
# Human review for critical tasks
if task.is_critical:
await self.queue_for_human_review(result)
return result
```
Adoption: 89% of enterprise agents include HITL mechanisms.
Benefits:
Emerging Standards:
Input Validation
```python
class SecureAgent:
def validate_input(self, user_input: str) -> bool:
# Check for prompt injection
if self.detect_prompt_injection(user_input):
raise SecurityError("Prompt injection detected")
# Check for PII
if self.contains_pii(user_input):
user_input = self.redact_pii(user_input)
# Check for malicious content
if self.is_malicious(user_input):
raise SecurityError("Malicious content detected")
return True
```
Output Filtering
```python
def filter_output(self, output: str) -> str:
# Remove any leaked system prompts
output = self.remove_system_prompts(output)
# Redact sensitive information
output = self.redact_sensitive_data(output)
# Check for harmful content
if self.is_harmful(output):
return self.safe_fallback_response()
return output
```
Market: AI security tools market at $1.2B, growing 140% YoY.
```python
def search_web(query: str) -> str:
return google_search(query)
agent.add_tool(search_web)
```
```python
from pydantic import BaseModel
class SearchParams(BaseModel):
query: str
max_results: int = 10
date_range: Optional[str] = None
@tool(params=SearchParams)
def search_web(params: SearchParams) -> List[SearchResult]:
return google_search(**params.dict())
```
```python
class AutonomousAgent:
async def execute(self, task: Task) -> Result:
# Analyze task requirements
required_capabilities = await self.analyze_requirements(task)
# Discover available tools
available_tools = await self.tool_registry.discover(required_capabilities)
# Learn tool usage from documentation
for tool in available_tools:
if not self.knows_tool(tool):
await self.learn_tool(tool)
# Execute with discovered tools
return await self.execute_with_tools(task, available_tools)
async def learn_tool(self, tool: Tool) -> None:
# Read tool documentation
docs = await tool.get_documentation()
# Generate usage examples
examples = await self.llm.generate_examples(docs)
# Test tool with examples
for example in examples:
try:
result = await tool.execute(example)
self.tool_knowledge.add_success(tool, example, result)
except Exception as e:
self.tool_knowledge.add_failure(tool, example, e)
