Summary
OpenAI made its Agents API available in public beta, letting all developers build production-ready long-running agents with a single API call.
The API packages the Codex harness and infrastructure OpenAI says it refined at scale, handling context management, tool use, subagent coordination, code execution, files and intermediate results over sessions that can last days.
Nine partners — including Cloudflare, Oracle, DigitalOcean and Vercel — are providing integrated sandbox options, while OpenAI also introduced its own hosted sandbox for managed code-running environments.
Pricing adds no separate API fee: developers pay only for the tokens and tools their agents consume, with OpenAI saying it will iterate toward general availability based on beta feedback.
