OpenAI announced new features at its DevDay conference in San Francisco. Codex can now scan GitHub repos for vulnerabilities and run automatic code reviews in the cloud. The company also launched a Decisions API that returns answers up to ten times faster than its regular model, and an Ultrafast tier that generates up to 300 tokens per second but costs six times the standard price.
Why it matters
These tools let developers catch bugs earlier, automate decision‑making, and speed up AI‑generated code, at the cost of higher usage fees.
