Intel Summary
OpenAI introduced multiple updates to Codex and its developer platform at DevDay 2026. Codex received reusable cloud environments, automated security scans for GitHub repositories, and a code review interface in the desktop application. Additionally, OpenAI added Computer Use support to the Agents API, launched a Decisions API for low-latency single decisions, and introduced an Ultrafast premium tier offering up to eight times faster execution at six times standard pricing.
Why It Matters
These additions expand OpenAI's developer stack into execution environments, code auditing, and direct UI interaction. Software engineering teams and enterprise developers gain direct infrastructure for agentic workflows and security reviews, while the Ultrafast tier and Decisions API introduce explicit cost-versus-latency trade-offs for production workloads.
