Anthropic just released Anthropic Academy. And it's completely free. 13 self-paced courses covering everything from Claude 101 to building with the API, Model Context Protocol (MCP), and enterprise cloud deployments. Three learning tracks: AI Fluency - for beginners or anyone using AI day-to-day Product Training - hands-on with Claude's tools Developer Deep-Dives - API, MCP servers, Claude Code No credit card, trial period, or upsell (I didn't see one). You sign up with an email and get access to everything (including certificates you can add to LinkedIn for my AI agency homies). There's even a Claude Code course, so you can finally stop watching your 5th "Claude Code Full Course (X Hours)" video and get the how-to guide from the people who actually built it. Whether you're brand new to AI or you've been using Claude daily, this is worth your time. In my opinion, Claude is the #1 LLM on the market right now, and learning it from the source is a no-brainer. Check it out here: https://anthropic.skilljar.com/
