Anthropic just dropped a 1-hour workshop on how to actually build with AI in 2026:
00:26 - Why they stopped prompting
16:57 - The system that builds, tests, and fixes itself
25:27 - One engineer replacing a 5-person team
36:25 - Building your first loop from scratch
This 1-hour watch could replace 10 AI engineering courses on the internet.
Watch it today, then read the step-by-step guide on building loops below.
We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.
