OpenAI releases new Agent: three major built-in tools. According to reports, OpenAI has released new tools and APIs designed specifically for building AI Agents. The core products released by OpenAI this time include Responses API and Agents SDK. The Responses API combines the simplicity of the Chat Completions API with the tool usage capabilities of the Assistants API, providing developers with a powerful infrastructure. With a single API call, developers can use multiple tools and models to solve complex tasks in turn, greatly simplifying the development process. Agents SDK is an open source multi-agent workflow orchestration framework. It allows developers to easily define agent roles and tools to achieve seamless task handover between agents. It also provides a security check mechanism and real-time monitoring functions to make the collaboration of agents more efficient and controllable. In order to make AI Agents more practical, OpenAI also provides three built-in tools, including web search tools, file search tools, and computer usage tools. The web search tool supports GPT-4o and GPT-4o-mini models, can crawl the latest data from the Internet in real time, and provide clear and relevant citation sources. This is like equipping agents with a real-time updated knowledge base, allowing them to keep abreast of the latest developments. File search tools support vector storage and metadata filtering to quickly and accurately retrieve relevant information from large numbers of documents. For enterprises, this is undoubtedly an efficient knowledge retrieval tool. Computer usage tools are equivalent to having Operators built into the API, which can automatically control the computer and implement complex operations such as clicking, inputting, and dragging. This is a huge breakthrough for scenarios that require interaction with traditional systems. OpenAI Chief Product Officer Kevin Weil mentioned in the live broadcast: 2025 will be the year of the explosion of AI agents, and it will also be the year that ChatGPT and our developer tools upgrade from 'just answering questions' to 'actually able to perform tasks for you in the real world.'
