Use this when you want Simon Willison's material for llm tools and related AI skills.
Developers, technical generalists should start here when they need llm tools, prompting, ai safety, local models, and model selection. The strongest fit is a learner who wants material in these formats: blog, open source tools.
Read the recent model-roundup posts, then try the llm command-line tool with two or three different providers. After that, open one related resource below and write down the exact workflow, concept, or implementation pattern you want to apply.
Consistently useful notes, demos, model comparisons, and warnings about practical LLM use without product marketing gloss. 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 llm tools, search the directory for that skill and shortlist three profiles before committing to a course, book, or playlist.
These are not by Simon Willison. They are included only as optional adjacent material after this educator's own videos and resources.
