OpenAI pushes AI agent capabilities with new developer API
1 min read
Summary
OpenAI has released a new Responses API to help developers create AI agents that can perform tasks alone using the company’s models.
The AI agents can use the file search utility to scan company databases and navigate websites.
The release of the Responses API means the retirement of the current Assistants API, which will happen in the first half of 2026.
Although OpenAI promises its CUA model can enable automation of tasks, it recognises that it is not yet reliable for operating systems and can make unintended errors.
The company views the new API as a starting point that will be enhanced over time.
With many tech companies investing in agentic AI features, Google has also announced its ambitious AI agent features, with OpenAI’s aims to have these AI agents join the workforce by 2025.
