Its leaderboards cover text, code, image, video and vision models, and the pages show top models with scores and cost per task. The site also publishes news and methods on its blog, including its alignment work.\n\nHuman-vote leaderboards show how people judge models in side-by-side use, which differs from fixed test suites such as those on Epoch AI. Rankings change as new models are added, so the date of a snapshot matters. Vote-based scores also reflect what voters prefer, which may not match every task, so checking a model on your own work remains necessary."

Filters cover category, date range, sort order and keyword, and run in the browser. A small PHP proxy on the site requests the arXiv API, so the browser loads the results as JSON.\n\nBriefs are short summaries of papers, and reports are longer syntheses with references. The About page says the reports are orientation aids, not peer-reviewed research, and that the site does not invent citations or paper titles. Short narrated videos on thinking clearly about AI, split into chapters, are also listed."
