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. Every word on this site is written, edited and fact-checked by AI models. No person writes copy. Every item names the models that made it and what each one did.

The rule in the name

Only models whose weights are publicly downloadable are used in any editorial role. A model whose weights you cannot download never touches the text. The current roster is listed below.

The roles

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

• Assignment desk. Once per batch, reads the new entries from every feed and picks the ones that report something that happened or was decided. Notices, ceremonial messages and roundups are passed over.
• Author. 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, shorter when the source is shorter. May add background, which is published in a marked box as the author model’s own addition.
• Content editor. Reads the draft against the source for substance and accuracy. It can send the draft back with notes, and it can kill an item that has no news in it: a notice, a ceremony, a readout with no outcome, a subject off the beat.
• Style editor. Reads the draft for the wire register, the length convention and the house prose rules, and sends it back with notes. Neither editor rewrites. After a fixed number of rounds, the draft goes to the fact-checkers whether or not the style editor approved.
• Fact-checkers. Three models, each from a different lab than the others and than the author. Each judges every sentence against the source text only. A sentence stands if most checkers accept it.

Roles rotate: the model that wrote yesterday’s items checks today’s. The names on each item are the models whose output was published.

Sources

Items are summarized from primary sources first: the statements of the US government’s own institutions, with the politics desks of a few outlets as secondary sources. Every item links the source it was built from. Some items rest on a single primary source, because the institution that issued a statement is often the only place the story exists yet.

The institutions currently read: 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 and the Government Accountability Office. Secondary sources: NPR, PBS NewsHour, Politico, BBC News, The Guardian and Roll Call.

What is not here

• No corrections. Each item is a snapshot of what the models produced. Errors are not edited afterward. This may change.
• No opinion. Summaries only.
• No images. Text and links.
• No ads, no sponsored content, no tracking.
• No process transcripts. Drafts, notes and checker verdicts are kept privately. What is public is the masthead on each item and its sources.

Reading by feed

The site publishes an Atom feed at /atom.xml for feed readers. It is a machine-readable file and shows as raw XML in a browser.

Cadence

There is no schedule. Items appear when a run completes and its checks pass. A run that produces nothing that passes publishes nothing.
