Trend followers stage recovery as stretched S&P, Nasdaq longs fuel gains
On Tuesday, OpenAI announced the release of several building blocks and tools to help developers create AI agents. In a livestream and subsequent news release, the company introduced Responses API, three additional tools, and Agents SDK.
The goal of these developer tools is to create systems capable of independently completing complex tasks on behalf of the user, at a time when enterprises are seeking AI agents that can operate with minimal supervision, increasing efficiency.
At the center of OpenAI’s announcement is the Responses API, which will serve as a replacement for the company’s existing interfaces. The system is meant to combine the simplicity of OpenAI’s Chat Completions API, while adding advanced capabilities available within its Assistants API.
Among the built-in tools the company is adding are Web Search, File Search, and Computer Use:
- Web Search allows models to access information directly from the internet to ensure more timely and accurate information. It is meant to excel at digesting large amounts of web data, sifting through to find relevant pieces, and clearly citing the source of information.
- File Search allows developers to retrieve important information by filtering through large volumes of documents. The File Search tool includes metadata filtering, in which users can add attributes to files to more easily find them, and direct search endpoint, which can directly search file storage without queries being first filtered through the model.
- Computer Use, powered by the same CUA model that enables the Operator tool, is used to enable AI agents to perform computer tasks. The current research preview of the tool reportedly set several benchmark records.
OpenAI also introduced Agents SDK, an open-source toolkit for orchestrating single and multi-agent workflows. Agents SDK is built upon last year’s experimental SDK Swarm, which was highly popular in the developer community.
The company announced that the Chat Completions API will still be available, but using the Responses API is recommended for new projects. The Assistants API will be deprecated in 2026 in favor of the Responses API.
