What you may use freely

These values, calculated and published by LastAI, are covered by CC BY 4.0.

  • LastAI Index scores (0–100), ranks within each field and group, and tiers (S–D)
  • Evidence grades (A, B, C), evidence weight and the 0–100 score given to each signal
  • Rises and falls in the LastAI Index weekly report
  • Every dated snapshot (the JSON and CSV downloads)
  • The ranking badges and the embeddable ranking tables

What belongs to others

  • Raw values from outside sources

    Numbers such as Tranco web rank, Wikipedia pageviews, GitHub stars, a16z ranks and revenue share from official filings belong to their sources. The downloads list a source URL (sourceUrl) for every value; to reuse a raw value on its own, follow that source's terms.

  • AI usage

    The numbers on the AI usage pages and in the AI usage weekly report are OpenRouter's published data, collected and compiled by LastAI. Please credit both, for example ‘OpenRouter data, compiled by LastAI’. The raw data stays under OpenRouter's terms.

  • Articles and pictures

    The text and pictures of the Daily AI Report, AI Encyclopedia, AI recipes, timelines and news summaries are not covered. Short quotations with the source and URL are fine. When citing a news summary, cite the original article rather than the summary.

  • Names and logos

    Company and product names and logos are their owners' trademarks; these terms do not license them.

How to credit us

Values in a dated snapshot never change, so adding the snapshot date lets readers check the same numbers later. On the web, linking the credit line to lastai.org is enough.

A few requests

  • Please don't suggest that LastAI endorses or co-produced your article or product.
  • The rankings measure how widely something is used and known, not its quality, safety or investment value.
  • The data is provided as is and may contain errors. If you find one, please tell us; corrections are logged on the editorial principles page.
  • The downloads refresh every five minutes and the badges and tables every hour, so there is no need to fetch them more often.
