We packed in a lot: * GPT‑5.6 * Ultra * New ways to manage parallel work * Big updates to Computer Use * Inline code and document edits * PR reviews * Sites * ...and much more. Make sure you watch until the end: something that isn’t out yet makes a cameo!

Makers residency 4th edition

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. An asset manager went on to raise an additional £25M on their fund within nine months. The fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
