AI BriefingNew Tools for Building Agents
Key point
OpenAI has released a new set of tools, including the Responses API and Agents SDK, to simplify agent development.
Details
OpenAI has released the first building blocks to help developers and enterprises build useful and reliable Agents. Agents refer to systems that independently perform tasks on behalf of users.
This update introduces the following core tools that reduce the complexity of agent development:
- Responses API: A new API primitive that combines the simplicity of Chat Completions with the tool-use capabilities of the Assistants API
- Built-in tools: Support for web search, file search, and computer use capabilities
- Agents SDK: An SDK for orchestrating single and multi-agent workflows
- Observability tools: Features to trace and inspect agent workflow execution
In particular, the Responses API provides a flexible foundation that can solve complex tasks using multiple tools and model turns in a single call. It serves as a superset of the existing Chat Completions API, and OpenAI recommends using the Responses API for new integration projects.
All developers can use the Responses API starting today, with the same token and tool-use rates applied as before, at no additional cost.
