OpenAI releases Agents API for autonomous cloud agents

By PulseAugur Editorial · [9 sources] ·

OpenAI has launched its Agents API in public beta, providing developers with access to the underlying infrastructure that powers Codex and ChatGPT. This new API allows for the creation of autonomous cloud agents capable of running for extended periods, executing code, and managing sub-agents. Developers can utilize OpenAI-hosted sandboxes, their own infrastructure, or partner environments from companies like Cloudflare and Oracle for agent computation. The service is designed to simplify agent development by handling complex tasks such as context management and long-running sessions, with costs primarily tied to model token usage. AI

IMPACT Enables developers to build more sophisticated autonomous agents with managed infrastructure, potentially accelerating AI application development.

RANK_REASON This is a product launch for a developer tool, not a frontier model release.
