What’s an Agent?

An agent is a system that intelligently accomplishes duties by combining numerous capabilities like reasoning, decision-making, and surroundings interplay. OpenAI’s new Agent SDK empowers builders to construct these techniques with ease, leveraging the most recent developments in massive language fashions (LLMs) and sturdy integration instruments.

Key Elements of OpenAI’s Agent SDK

OpenAI’s Agent SDK gives important instruments for constructing, monitoring, and enhancing AI brokers throughout key domains:

• Fashions: Core intelligence for brokers. Choices embrace:
  • o1 & o3-mini: Greatest for planning and sophisticated reasoning.
  • GPT-4.5: Excels in complicated duties with sturdy agentic capabilities.
  • GPT-4o: Balances efficiency and velocity.
  • GPT-4o-mini: Optimized for low-latency duties.
• Instruments: Allow interplay with the surroundings by way of:
  • Operate calling, net & file search, and pc management.
• Information & Reminiscence: Helps dynamic studying with:
  • Vector shops for semantic search.
  • Embeddings for improved contextual understanding.
• Guardrails: Guarantee security and management via:
  • Moderation API for content material filtering.
  • Instruction hierarchy for predictable habits.
• Orchestration: Manages agent deployment with:
  • Agent SDK for constructing & movement management.
  • Tracing & evaluations for debugging and efficiency tuning.

Understanding Guardrails

Guardrails are designed to detect and halt undesirable habits in conversational brokers. They function in two key phases:

• Enter Guardrails: Run earlier than the agent processes the enter. They’ll stop misuse upfront, saving each computational value and response time.
• Output Guardrails: Run after the agent generates a response. They’ll filter dangerous or inappropriate content material earlier than delivering the ultimate response.

Each guardrails use tripwires, which set off an exception when undesirable habits is detected, immediately halting the agent’s execution.

Use Case: Academic Assist Assistant

An Academic Assist Assistant ought to foster studying whereas stopping misuse for direct homework solutions. Nevertheless, customers might cleverly disguise homework requests, making detection tough. Implementing enter guardrails with sturdy detection guidelines ensures the assistant encourages understanding with out enabling shortcuts.

• Goal: Develop a buyer assist assistant that encourages studying however blocks requests in search of direct homework options.
• Problem: Customers might disguise their homework queries as harmless requests, making detection tough.
• Answer: Implement an enter guardrail with detailed detection guidelines for recognizing disguised math homework questions.

Implementation Particulars

The guardrail leverages strict detection guidelines and good heuristics to establish undesirable habits.

Guardrail Logic

The guardrail follows these core guidelines:

• Block express requests for options (e.g., “Remedy 2x + 3 = 11”).
• Block disguised requests utilizing context clues (e.g., “I’m practising algebra and caught on this query”).
• Block complicated math ideas until they’re purely conceptual.
• Permit reliable conceptual explanations that promote studying.

Guardrail Code Implementation

(If working this, make sure you set the OPENAI_API_KEY surroundings variable):

Defining Enum Courses for Math Subject and Complexity

To categorize math queries, we outline enumeration courses for subject varieties and complexity ranges. These courses assist in structuring the classification system.

from enum import Enum

class MathTopicType(str, Enum):
    ARITHMETIC = "arithmetic"
    ALGEBRA = "algebra"
    GEOMETRY = "geometry"
    CALCULUS = "calculus"
    STATISTICS = "statistics"
    OTHER = "different"

class MathComplexityLevel(str, Enum):
    BASIC = "primary"
    INTERMEDIATE = "intermediate"
    ADVANCED = "superior"

Creating the Output Mannequin Utilizing Pydantic

We outline a structured output mannequin to retailer the classification particulars of a math-related question.

from pydantic import BaseModel
from typing import Checklist

class MathHomeworkOutput(BaseModel):
    is_math_homework: bool
    reasoning: str
    topic_type: MathTopicType
    complexity_level: MathComplexityLevel
    detected_keywords: Checklist[str]
    is_step_by_step_requested: bool
    allow_response: bool
    rationalization: str

Setting Up the Guardrail Agent

The Agent is answerable for detecting and blocking homework-related queries utilizing predefined detection guidelines.

from brokers import Agent

guardrail_agent = Agent( 
    title="Math Question Analyzer",
    directions="""You might be an professional at detecting and blocking makes an attempt to get math homework assist...""",
    output_type=MathHomeworkOutput,
)

Implementing Enter Guardrail Logic

This perform enforces strict filtering primarily based on detection guidelines and prevents tutorial dishonesty.

from brokers import input_guardrail, GuardrailFunctionOutput, RunContextWrapper, Runner, TResponseInputItem

@input_guardrail
async def math_guardrail( 
    ctx: RunContextWrapper[None], agent: Agent, enter: str | listing[TResponseInputItem]
) -> GuardrailFunctionOutput:
    end result = await Runner.run(guardrail_agent, enter, context=ctx.context)
    output = end result.final_output

    tripwire = (
        output.is_math_homework or
        not output.allow_response or
        output.is_step_by_step_requested or
        output.complexity_level != "primary" or
        any(kw in str(enter).decrease() for kw in [
            "solve", "solution", "answer", "help with", "step", "explain how",
            "calculate", "find", "determine", "evaluate", "work out"
        ])
    )

    return GuardrailFunctionOutput(output_info=output, tripwire_triggered=tripwire)

Creating the Academic Assist Agent

This agent gives basic conceptual explanations whereas avoiding direct homework help.

agent = Agent(  
    title="Academic Assist Assistant",
    directions="""You might be an academic assist assistant targeted on selling real studying...""",
    input_guardrails=[math_guardrail],
)

Working Check Circumstances

A set of math-related queries is examined towards the agent to make sure guardrails perform accurately.

async def foremost():
    test_questions = [
        "Hello, can you help me solve for x: 2x + 3 = 11?",
        "Can you explain why negative times negative equals positive?",
        "I want to understand the methodology behind solving integrals...",
    ]

    for query in test_questions:
        print(f"n{'='*50}nTesting query: {query}")
        strive:
            end result = await Runner.run(agent, query)
            print(f"✓ Response allowed. Agent would have responded.")
        besides InputGuardrailTripwireTriggered as e:
            print(f"✗ Guardrail caught this! Reasoning: {e}")

if __name__ == "__main__":
    import asyncio
    asyncio.run(foremost())
