Methodology
Evidence statuses
Every fact carries one of six statuses. The status says how far the fact is checked; it is not a rating of the product.
- Checked against an official or independent source.
- Stated by the developer or provider and not independently checked.
- Derived by the editors from other recorded values; the derivation is shown with it.
- Another source contradicts it. Both are kept, and it is not ranked until an editor resolves it.
- No source reports it. It is written out as unknown and never shown as zero.
- Not rechecked within the expected time; shown with the date of the last check.
Importance in the feed
“Important” orders events by the importance the editors record when they publish an event — high, medium or low — and then by publication time. Importance is about the effect on readers, such as a critical advisory or a price change; it is not a measure of attention.
“Latest” shows events by publication time only. Updates to existing events are shown apart from new events.

Open the event feedPricing
Every price names the exact offer: the provider, the model version or plan, the billing unit, the tier, the region and the date it took effect.
- A price not rechecked for 14 days is shown as last known, with its date.
- A promotional price is marked as such. A price on request stays “On request”: it is never estimated or averaged.
- The calculator uses the published prices of the offers you choose; a missing price blocks the exact total instead of being guessed.
Comparisons
Only like is compared with like: model versions with model versions, agents with agents, tools with tools of the same type. A model is never compared with an agent.
An unknown value never counts as a match or as a difference. “Best” is marked only between direct alternatives, and only when one value is strictly better.

Open the comparisonBenchmarks
A score is shown with the benchmark version, the unit, the harness, the snapshot and the run date. There is no overall winner across benchmarks.
- Only published results in a comparable cohort get a place.
- A developer's claim without a published source is shown apart and is not ranked.
- A run with a different harness, prompt budget or benchmark version is excluded from the ranking, with the reason.
- Price-performance uses the lowest published API input price of the same model version and is shown with its formula.
Trending
Trending lists the releases of an explicit period — 7, 30 or 90 days, or all; 30 by default — ranked by a dated snapshot of repository stars. It is a view of published records over time, not a measure of quality, and withdrawn records never trend.

Open Open Source RadarOpen source
Open weights, open source code and commercial use are three separate facts. A licence is shown with what it covers and what it says about commercial use; “Not stated” is never read as permission.
Hardware estimates use the stated parameter count at 16, 8 and 4 bits. Links go to the publisher's page or repository, never to a download.
Research
Bibliographic data is kept apart from the editors' reading. Why a paper was selected and what is new in it are editorial judgement, labelled as such, never a score.
Peer review is taken from the publisher's record: a preprint or “Not reported” is never counted as peer-reviewed. An authors' revision is a new version of the paper, not a correction.
Security
Each incident shows its severity as its source publishes it, the affected and fixed versions and the disclosure status. The editors do not re-score severity, and no CVSS score or CVE identifier is invented.
No record of an incident is not a safety rating. A missing fix date does not mean the issue is fixed, and embargoed details stay hidden until the embargo ends.
Compatibility
A check names the product version and the protocol version it covers and fills only that cell of the matrix. Each cell is Supported, Partial, Not supported or Not checked, with its basis and evidence.
A developer's own listing is “Not checked”. A check older than 90 days is marked as possibly out of date.
Sources in the register
Each check cites its own source; the matrix shows it on every cell.

An issue lists only stories reviewed and published in its period, each once, linking to its report. A day or week without a reviewed story has no issue; nothing is added to fill it.
A corrected issue says what changed and when, and keeps its original publication time.
