Anthropic released a free, registration-free 27-minute workshop teaching you how to prompt their Claude AI, led by its creators. It packs practical techniques into the first eight minutes that rival paid courses.

Boris Cherny breaks down nine common habits that burn most of your Claude tokens before the model even sees your prompt—loading CLAUDE.md, rereading chat history, forgotten hooks, and more. He shows how each pattern eats into your limits and why complaints about “Claude getting dumber” usually miss the real culprit.

Anthropic's AI tool, Claude, has gained significant traction among consumers, with paid subscriptions more than doubling this year. The growth coincides with a public feud with the Department of Defense and effective Super Bowl ads that positioned Claude as a safer alternative to competitors. Despite this success, Claude still trails behind ChatGPT in overall user numbers.

Engineers from Anthropic break down Claude’s design, covering its transformer-based architecture, data curation methods, and reinforcement learning from human feedback. They also dive into safety measures and guardrails built to curb harmful or biased outputs.
