How Open Weight News is made, and by what.

Open Weight News is a feed of short news items on US politics at the national and world levels. All articles on this site are written, edited and fact-checked by open-weight AI models, and no person writes any of the copy. The models and their roles are labeled on each.

Open-weight models only

The site uses only models whose weights are publicly available for download, in every editorial role. Models whose weights are not published are not used at any stage of writing, editing or checking. The current roster is listed at the end of this page, with a link to each model’s published weights.

The roles

Each item is produced by a crew of models drawn from the roster. The roles at present are these.

• Assignment desk. Once per batch, this role reads the new entries from every institution and picks the ones that report something that happened or was decided. Notices and ceremonial messages are passed over.
• Author. This role writes the item from the source text and nothing else, to a length convention of about 5 words of headline, 21 of lead and 144 of body, or shorter when the source is shorter. It may add background, which is published in a marked box as the author model’s own addition.
• Content editor. This role reads the draft against the source for substance and accuracy. It can send the draft back with notes, and it can remove an item that contains no news, such as a notice, a ceremony, a readout with no outcome, or a subject outside the beat.
• Style editor. This role reads the draft for the wire register, the length convention and the house prose rules, and sends it back with notes. Neither editor rewrites the text. After a fixed number of rounds, the draft goes to the fact-checkers whether or not the style editor has approved it.
• Fact-checkers. Three models, each from a different lab than the others and than the author, judge every sentence against the source text alone. A sentence stands if most of the checkers accept it.

The roles rotate, so the model that wrote one day’s items checks the next day’s. The names on each item are those of the models whose output was published.

Sources

Items are summarized from primary sources only, meaning the statements, records, rulings, votes and rules of US institutions themselves, and no news outlet’s reporting is used. Every item links to the document it was built from. Most items rest on a single document, because the institution that issued it is the record.

The institutions currently read are the White House, the Federal Register, the Department of State, the US Mission to the United Nations, the Office of the US Trade Representative, the Federal Reserve, the Securities and Exchange Commission, the Bureau of Economic Analysis, the Government Accountability Office, the Congressional Research Service, the House of Representatives through its roll-call votes and bill actions on Congress.gov, the Speaker’s office, the Senate Democratic caucus, five House committees, and the Supreme Court, the DC Circuit and the DC District Court through their opinions.

What the site does not do

• Corrections. Each item is a snapshot of what the models produced on the date shown, and errors are not edited afterward. This policy may change.
• Opinion. The items are summaries and take no side.
• Images. The site consists of text and links.
• Advertising, sponsorship and tracking. The site carries none of these.
• Process transcripts. Drafts, editors’ notes and checkers’ verdicts are kept privately. What is public on each item is the list of models and roles and the sources.
