Our last coding camp of the year isCodex Camp—a live workshop about building with OpenAI’s coding agent, open to all Every subscribers on Friday, December 12 at 12 p.m. ET.Learn more and reserve your spot.—Kate LeeWas this newsletter forwarded to you?Sign upto get it in your inbox.Every’s take on Anthropic’s latest model,Opus 4.5, is that it’s a world-changing shift in AI-powered coding.When Every CEODan Shipperstarted usingOpus 4.5, his previous frustrations with AI coding—errors, hallucinations—disappeared. After the model was released in late November he built his dream reading app between meetings in one week, work that would havetaken him six months before.Meanwhile, resident Claude Code wizardKieran Klaassenwas so enamored with the model, he started 10 projects at once and kept sneaking away from Thanksgiving dinner to prompt more. “This is by far the most exciting model, maybe ever,” he said.We knew we needed to do more than write about what we were seeing. We needed to show it. Cue our latest Claude Code Camp.Over the course of the hour, Dan and Kieran walked more than 400 Every subscribers through what they’ve discovered working with Opus 4.5. They demoed real workflows, shared emerging patterns in how to think about code, and answered questions about everything from how to take advantage of the model’s new-and-improved computer use capabilities to what this means for thecompound engineeringplaybook.Here’s what we learned—and what you can apply immediately.Become apaid subscriber to Everyto unlock this piece and learn about:The five things that have shifted about AI coding with Opus 4.5Why Dan calls Opus 4.5 “the infinite coding machine”—and what broke with every model before itThe bottleneck that occurs when your AI can handle 10 projects at onceSubscribeClick hereto read the full postWant the full text of all articles in RSS?Become a subscriber, orlearn more.Book information
