OpenAI released the Agent SDK, making AI agent building easier
It comes with the Responses API and built-in tools like web search and file search
Supports multi-agent workflows, automatic task delegation, and debugging tools
Works with Python and lets devs turn any function into an AI tool
Open-source and flexible—not locked to OpenAI models

OpenAI just launched the Agent SDK—a toolkit that helps devs build AI that can do more, not just understand stuff. It comes with the Responses API and a set of built-in tools, making AI agents more useful with less human input.

What’s Inside?

Responses API

This mixes the best of OpenAI’s past APIs. It’s got the ease of Chat Completions and the tool-handling skills of the Assistants API. Now devs can create AI that tackles multi-step tasks without needing constant guidance.

Built-in Tools for Smarter AI

Web Search. AI can grab real-time info from the web, just like ChatGPT’s browsing feature.
File Search. AI can sift through huge piles of docs in different formats.
Computer Use. AI can operate software, automate tasks like data entry, and even browse the web—powered by OpenAI’s Computer-Using Agent (CUA) model, the same tech behind OpenAI’s Operator agent.

Agent SDK

This open-source toolkit helps AI agents work together smoothly. Some big perks:

Pre-set language models with built-in instructions
AI that can switch tasks between agents
Safety features to prevent bad outputs
Debugging tools to catch mistakes early
Works with models from different providers-not locked to OpenAI

Why This Matters

This update makes AI way more useful. Whether it’s pulling live data, handling tricky workflows, or working with other digital tools, AI can now act on information—not just process it. And since the SDK is open-source, devs can tweak it however they want.

1. Lightweight Yet Powerful

This toolkit is small but mighty. Unlike older AI frameworks, it’s built for real-world use. You can spin up working AI agents with just a few lines of code.

2. Python-Friendly

No need to learn complicated new systems. The SDK uses Python so devs can start right away—just like writing regular Python scripts.

3. Automatic Task Handling

Normally, making AI work through tasks needs tons of code. This SDK automates the looping logic so AI can:

Execute tasks
Send results to the language model
Keep going until the job’s done

4. Turn Any Python Function Into an AI Tool

With one simple decorator, devs can turn any Python function into an AI tool. The SDK even handles schema generation and validation automatically.

5. AI Agents That Work Together

AI can now delegate tasks between different agents—like a team of specialists. Picture an AI assistant that splits a big request into parts, assigns each to the right agent, then pulls everything together in the end.
