Guides
Intermediate to advanced
Use this when you want Hamel Husain's material for evals and related AI skills.
Builders shipping LLM systems should start here when they need evals, rag, and llm product quality. The strongest fit is a learner who wants material in these formats: guides, workshops.
Read the evals guide and build a small test set for your own app. After that, open one related resource below and write down the exact workflow, concept, or implementation pattern you want to apply.
Very practical material on evaluating LLM apps before they disappoint users. Use this profile when you are comparing educators by topic, level, format, and practical usefulness rather than browsing random AI content.
Compare the skill coverage, the starting recommendation, the educator's own resources, and any videos when available. If you need evals, search the directory for that skill and shortlist three profiles before committing to a course, book, or playlist.
