Code Mode: Let the Code do the Talking - Sunil Pai, Cloudflare

Sunil Pai from Cloudflare discusses "Code Mode," an approach to interacting with AI agents where the model generates executable code (such as JavaScript) instead of relying on traditional JSON-based tool calling. This shift allows for more efficient, stateful, and complex system interactions. Speaker info: Sunil Pai created Partykit, the open source tool for real-time multi-player apps. For his day job, he builds AI Agents at Cloudflare. - https://sunilpai.dev/ - blog.cloudflare.com/author/sunil/ - linkedin.com/in/sunil-pai-a47732253/ Timestamps 0:00 Introduction and speaker background 1:16 What is "Code Mode"? 1:31 Limitations of traditional tool calling at scale 2:03 The shift to generating executable code 3:01 Scaling API usage at Cloudflare 4:05 Why code generation is more efficient 5:28 Live demonstration of the Mythical server 7:20 A new way of interacting with systems 9:09 Example: The Kenton canvas and tic-tac-toe anecdote 11:46 New software architecture: The "Harness" 13:28 Observability and security in sandboxed environments 14:15 Long-running workflows and generative UI 16:41 Future outlook: Building for the next generation of users 17:50 The resurgence of capability-based security 18:33 Conclusion and final thoughts
