1. OpenAI Powers Cloudflare Agent Cloud Expansion with GPT-5.4 and Codex

OpenAI. Cloudflare expanded its Agent Cloud platform with deep OpenAI integration, bringing GPT-5.4 and Codex to enable enterprises to build, deploy, and scale production-grade AI agents. The announcement introduced Dynamic Workers, an isolate-based runtime that spins up in milliseconds to run AI-generated code in secure sandboxes at 100x the speed and a fraction of the cost of containers. Following Cloudflare’s acquisition of Replicate, developers can switch between proprietary models like GPT-5.4 and open-source alternatives by changing a single line of code. Source
