GradūsGradūs is Latin for a step — a degree, a stage on a climb. Same root as grade and graduate. The old primers were called Gradus ad Parnassum: a step toward mastery. Not a dump of courses. The next honest step.

The product is the PATH — the courses stay free and official

You do not need another AI course. You need to know where to start.

Official training is already free. The hard part is that the ground moves — models, tool gates, who owns the open hub — faster than any static syllabus. Gradūs places you, then keeps the next module honest.

Independent product. Not affiliated with any lab. We link; we do not rehost.

This week is why the map is the product

NVIDIA reported in talks to buy Hugging Face for about $12.9 billion

If it closes, the main public hub for open models sits under the chipmaker. L4 paths that send people to huggingface.co/learn stay valid today. Do not rewrite résumés around “independent HF” until the deal is confirmed.

Grok Bot is on SuperGrok ($30/mo), not only Heavy

In two weeks the gate moved Heavy → Plus → SuperGrok. If the office default was “bots are a $300 toy,” that sentence is already stale. Human gate before it sends mail or touches a client file.

Microsoft AI-900 already retired (June 30). AI-901 is the live fundamentals exam (~$99)

Old study plans still say AI-900. Career members: free badges first; pay $99 only when the résumé line needs the current Microsoft code.

The scale

L0OrientingYou know AI exists. You do not yet have a reliable way to use it at work.
L1UserYou can open a chat tool and get a first draft. Results are uneven because prompts and review habits are thin.
L2PractitionerYou use AI most weeks. You need structure: better prompts, file context, and a verify-before-send habit.
L3OperatorYou run repeatable workflows. Next leap is evaluation, projects, and light automation.
L4BuilderYou can design multi-step systems. Focus on agents, evals, permissions, and production judgment.
