How we check a claim
Every receipt follows the same five steps. If we can't complete one, we say which.
1. Pin down the exact claim
We quote the claim as made, with who made it and when, and link where it appeared. If a headline paraphrases a company, we go back to the company's own words.
2. Find the primary source
Lab blog posts, model cards, papers, filings and official pricing pages come first. Secondary coverage is used for context and labelled as such. A screenshot of a post is never proof.
3. Ask who measured it
Vendor-reported benchmarks are flagged as vendor-reported. We prefer independent evaluations and note when the comparison set was chosen by the vendor.
4. Show the math
We itemize: the numbers, what they're compared against, and anything temporary, plan-gated or undisclosed (sample sizes, failure counts, model names, dates). Estimates are labelled as estimates.
5. Give a verdict
| Verdict | Meaning |
|---|---|
| ✅ Checks out | The numbers support the claim as stated. |
| ⚠️ Partly | True with important conditions, or only part of the claim holds. |
| ❌ Doesn't add up | The evidence contradicts the claim, or the claim can't be supported. |
Prices
The price tracker only lists prices read directly from the provider's official pricing page. Each row records the source URL and the date checked. Introductory prices are marked with their end date.
When we're wrong
We fix it in public. See the corrections policy and log.
