OpenAI Introduces Responses API and Agents SDK for Custom AI Development
OpenAI releases a new Responses API, Agents SDK, and observability tools to simplify the creation of production-ready AI agents. These tools combine chat capabilities with advanced tool use to handle complex, multi-step tasks.
OpenAI announces the new Responses API, the Agents SDK, and observability tools to help developers overcome the challenges of creating production-ready AI agents. The company states that agents will soon become a core part of the workforce, boosting productivity across industries by completing complex tasks through advanced reasoning and multi-modal interactions. These new tools aim to streamline the process of building agentic workflows directly on the OpenAI platform.
The Responses API combines chat completions with assistant capabilities, serving as the recommended foundation for new projects over the older Chat Completions and Assistants APIs. A single API call allows developers to tackle complex tasks using multiple tools and model turns. The API also includes built-in support for external tools like web search, local file search, and computer control that simulates mouse and keyboard inputs.
Developer feedback drives several improvements in the new API, such as a unified design, simpler polymorphism, enhanced streaming, and helpful SDK helpers. While the web search tool achieves up to 90% accuracy on the SimpleQA benchmark by leveraging ChatGPT's search models, the computer use tool only scores 38.1% on the OSWorld benchmark, indicating it is not yet highly reliable for operating system automation. Despite these limitations, the existing Chat Completions and Assistants APIs remain available for current users.
