How we source
A reference is only worth the weakest claim in it. Every fact on this site is graded into one of four tiers, and the tier decides how firmly it may be stated.
- TIER 1Official202 citations
Anthropic websites, documentation, help centre, Academy, system cards, official repositories and status pages.
What it licensesStated as fact.
- TIER 2Official partner2 citations
AWS, Google Cloud, Microsoft and other documented integration partners.
What it licensesStated as fact, attributed to the partner.
- TIER 3Verified third party0 citations
Project maintainers, source repositories, release pages and original research.
What it licensesStated as fact, attributed to the maintainer or author.
- TIER 4Community report0 citations
Forums, social posts and user testing. Reported, not independently verified.
What it licensesLabelled "community reported". Never stated as settled fact.
Rules that follow from the tiers
- No source, no claim. If a number cannot be traced to a citable page, the field is left empty and rendered as "not documented" — never filled in from memory, and never inferred from a similar product.
- "Not documented" is not "no". A blank cell in theavailability matrix means this reference could not find a public source, not that the feature is unavailable.
- Tier 4 stays labelled. Community reports can be genuinely useful — they are often the first signal a limit changed — but they are marked as reported and are never promoted to fact without a higher-tier confirmation.
- Dates beat prose. Every page says when it was last checked. An unverified claim from eight months ago is treated as suspect regardless of how confident it sounds.
- Automation proposes, a human decides. Change monitoring can flag that an official page moved; it does not get to publish the rewrite unreviewed.
