OpenAI Supercharges Codex at DevDay

🔥 What happened At DevDay 2026 in San Francisco, OpenAI rolled out a major Codex expansion: reusable cloud environments, voice-controlled CLI, code review in the desktop app, and Codex Security Cloud that automatically scans repositories for vulnerabilities. The Agents API gains Computer Use, a Decisions API built on GPT-6 Luna, and an Ultrafast tier that boosts token generation to 300 tokens/sec – at six times the standard price. 💡 Why it matters OpenAI is turning Codex from a coding assistant into a full-fledged agent platform. The Decisions API is ten times faster than GPT-6 Luna through the regular API and targets the emerging System-1 model market. Ultrafast costs six times more – a clear signal that speed is becoming a premium feature. ⚡ Our take OpenAI isn't just shipping features; it's building an ecosystem that locks developers in deeper. The Ultrafast price is steep, but if you want real-time agent control, you'll pay it. The question is whether competitors can match speed and price.
