OpenAI expands Codex and its API at DevDay with security scans, a Decisions API, and Ultrafast
OpenAI's DevDay 2026 adds Codex Security Cloud repo scanning, Computer Use in the Agents API, a Decisions API, and an Ultrafast tier.
At DevDay 2026 in San Francisco, OpenAI announced reusable cloud environments for Codex, a reworked Codex CLI with voice control, and a code review view in the ChatGPT desktop app. Codex Security Cloud scans entire GitHub repositories on demand or on schedule, investigates findings, deduplicates, and prepares fixes, with access to Daybreak Blue defensive models. The Agents API gains Computer Use, multi-agent features, Tool Search, and Context Compaction, and AWS Bedrock Managed Agents now supports building OpenAI agents running entirely on AWS. A Decisions API built on GPT-6 Luna returns answers ten times faster, while the Ultrafast tier reaches 300 tokens per second in Codex at six times standard API pricing ($60/$300 per million tokens for GPT-6 Astra).
