OpenAI Releases Agents API Public Beta
On September 10, 2026, OpenAI released the Agents API as a public beta, exposing the underlying infrastructure used by Codex and ChatGPT to third-party developers. The API allows developers to build cloud agents that run autonomously for hours, execute code, and hand off tasks to sub-agents without incurring extra fees beyond standard token usage. Major cloud providers, including Cloudflare, Vercel, and Oracle, have already begun offering additional sandbox environments to support these agents.
ChatGPT Work Adds Data Agent and Financial Services Integration
Also on September 10, OpenAI launched a new "Data agent" specifically for the ChatGPT Work suite, designed to automate enterprise analytics, dashboard creation, and business intelligence tasks. In parallel, the company announced "ChatGPT for Financial Services," a specialized integration that builds on earlier MCP connectors from PitchBook and LSEG. This move centralizes financial data access within the platform, following the March 2026 release of GPT-5.4 which first integrated these financial tools.
ASD Releases Agentic AI Security Guidance
On September 10, the Australian Signals Directorate (ASD) released new security guidance titled "Agentic AI Harnesses." The document outlines necessary security, governance, and operational controls for organizations adopting agentic AI systems. This regulatory move follows recent incidents where prompt injection attacks compromised agents, emphasizing that credential management and permission scopes are critical to limiting blast radius.
