Show Notes
In this episode of This Week in NET, host João Tomé is joined by Michelle Chen from Cloudflare’s AI product team to discuss the rise of open models, the launch of Kimi 2.5 on Workers AI, and why enterprises are rethinking the cost of proprietary AI.
Michelle explains how Cloudflare’s security team used Kimi to scan internal codebases and found more than 40 confirmed security issues — at a fraction of the cost of proprietary models. The conversation explores why open models are rapidly becoming competitive with closed alternatives, how Cloudflare builds efficiency with custom inference engines and prefix caching, and what the Replicate acquisition means for bring-your-own-model workflows on Workers AI.
Later in the episode, we also hear from Dina Kozlov about Dynamic Workers and Code Mode (now in open beta), followed by another Women of Cloudflare segment with Alexandra Messe Rodriguez. ⏱️ Timestamps
