Last night, a tech talk event was held at Cloudflare HQ, where five engineers from Coframe, Weaviate, Jam, Twilio, and Cloudflare shared their expertise on AI demos, prompt engineering, vector DBs, AI codegen, and user interface design. The talks covered topics such as building safe AI chatbots, thinking systematically to build amazing AI experiences, and the history of UI design, with a focus on how AI will change development of user interfaces. The event was attended by 75 engineers who packed into Cloudflare HQ for an evening of lightning talks, which were recorded and made available online.
