In this short episode of This Week in NET, Craig Dennis, Senior Developer Educator for AI at Cloudflare, explains why Replicate is joining Cloudflare, and what that means for developers building with AI.Replicate is widely known for making it easy to run thousands of high-quality AI models, from image generation and video to audio and language models, all through a simple, developer-friendly API. Craig breaks down why Replicate became such an important part of the AI ecosystem, and how bringing it into Cloudflare helps make Workers the best place to build and deploy AI and agentic workflows.And there’s a bonus: we’re giving away Replicate credits so you can try models yourself.

In this episode of This Week in NET, we talk with Daniele Molteni, Director of Product Management for Cloudflare’s WAF, about how Cloudflare responded within hours to a newly disclosed React Server Components vulnerability — deploying global protection before the public advisory was even released.That speed matters. In just the first 11 days after disclosure, Cloudflare observed more than 1 billion exploitation attempts related to React2Shell, with sustained pressure averaging over 4 million hits per hour, and peaks far higher. Threat actors quickly integrated the vulnerability into large-scale scanning and reconnaissance, targeting even critical infrastructure. If you run React, upgrading is urgent.Daniele explains how WAF rules are built, how new payload logging improvements help customers understand real attack traffic, and what’s coming next in 2026 — including Firewall for AI, fraud detection, and safer, gradual rule rollouts.To close the episode, Systems Engineer Steve James gives a hands-on demo of a real-time multiplayer chess app running inside ChatGPT, built with the Agents SDK and Cloudflare Workers.Mentioned blog posts:React2Shell and related RSC vulnerabilities threat brief: early exploitation activity and threat actor techniquesCloudflare WAF proactively protects against React vulnerabilityGet better visibility for the WAF with payload logging

In this episode of This Week in NET, host João Tomé sits down with Stephanie Cohen, Cloudflare’s Chief Strategy Officer, for a candid conversation about AI, content creators, financial services, partnerships, and the future of the Internet.Stephanie shares how Cloudflare is helping keep the Internet open and resilient — from giving creators transparency and control over AI scraping, to enabling new models of agentic commerce through partnerships with Visa and Mastercard, to empowering organizations of all sizes through Cloudflare’s global network.The conversation also explores the rise of Agentic Commerce, where AI agents can complete secure payments on behalf of users.
