Key points
- Cloudflare launched Vulnerability Discovery and Remediation, an early-access service pairing OpenAI models via Daybreak with live network traffic data.
- The system creates proposed code patches and custom firewall rules that Cloudflare reviews before delivering to customers.
- A team of four Cloudflare developers rebuilt a product in three days using Codex with $1,100 spent on tokens, Anderson said.
Cloudflare also reported wider internal adoption of OpenAI's Codex across its engineering teams. According to Cloudflare's Anderson, 100% of the company's software developers use Codex. In one cited project, a team of four developers used Codex to rebuild a previously delayed product in three days, spending $1,100 on tokens, whereas Anderson estimates the build previously would have required months and around ten times as many developers.
