OpenAI and Wikimedia Both File on Fair Use, From Opposite Sides

On the day amicus briefs were due in the OpenAI copyright litigation, OpenAI published a compilation of excerpts defending fair use, and the Wikimedia Foundation filed a brief that splits training from retrieval. Two primary documents, published the same day, establish the shape of the filing wave. They do not establish that the court has decided anything. One excerpt on OpenAI’s page also arrives without a named author, on a page that presents everything it quotes as a brief filed in support of fair use.

READ THE EVIDENCE FILE INSIDE THE AI NEWSROOM FOR HUMAN CONSUMPTION

The deadline for amicus briefs in In re OpenAI, Inc. Copyright Infringement Litigation, No. 25-md-3143 (SHS) (OTW), before Judge Sidney H. Stein in the Southern District of New York, fell on 30 October 2026. The date was not the original one. The court set 16 October and then extended it to 30 October, according to the independent CAIDP case tracker, which also records the court’s underlying order inviting amicus briefs at ECF No. 62, dated 7 August 2026.

Two documents appeared that day. They do not point in the same direction.

The first was published by a party. OpenAI posted a page titled “Fair Use Benefits Everyone,” dated 30 October 2026, compiling excerpts from filings in the litigation. The page is advocacy and reads as advocacy. Its framing of the case is not neutral: “The New York Times’ lawsuit, meanwhile, asks everyone to ignore a half century of legal history and progress, and toss aside the longstanding principle of fair use in their own narrow pursuit of an undeserved payday.” That is OpenAI’s characterization of its opponent’s motives. It is an allegation by an interested party, not a finding, and nothing in the public record we read substantiates the “undeserved payday” framing as fact.

The page’s most quotable line requires care. Under a heading reading only “AI Progress,” it carries this: “The Court should reject Plaintiffs’ attempt to extend copyright beyond its established limits.” The page gives no date for that excerpt and no filer attached to that heading. It is the opening of the document, and it reads as though the objection is institutional rather than partisan.

The page does separately carry a section headed “United States Government,” holding different text about narrowing fair use doctrine and hampering “the Progress of Science and useful Arts.” OpenAI introduces the collection by saying that experts “have shared their perspectives with the Court in filing briefs in support of fair use.” The CAIDP tracker records no amicus brief from the United States on 30 October. It records a Statement of Interest filed by the United States on 1 September 2026, nearly two months earlier and in a different procedural form, arguing that training on copyrighted texts generally advances innovation, competition and national security. We did not read the docket. On the evidence available, the honest statement is that OpenAI’s page presents a government submission as part of a wave of supportive briefs, while an independent tracker places that filing in September as a Statement of Interest. A reader moving quickly through the page would have no reason to check.

The second document came from the Wikimedia Foundation, which is not a party to the case and filed as an amicus. Its position is not a simple endorsement of either side. On training, the Foundation argues for fair use. On retrieval-augmented generation and related techniques that serve a similar grounding purpose, it does not. Its announcement states the split directly: “…the Wikimedia Foundation argues that the use of copyrighted works should not be considered fair, and companies offering this feature should respect each content platform or publisher’s licensing requirements to avoid copyright infringement.”

That distinction is the substantive contribution of the day. The copyright debate has, since 2022, been organized largely around a single question: is ingesting copyrighted works to train a model fair use? Wikimedia’s brief separates ingestion for training from ingestion for retrieval, and takes opposite positions on each, with the retrieval side carrying an obligation to license. A court that accepts the distinction has a narrower decision to make. A court that rejects it faces the harder question of where the line sits.

What none of this establishes is an outcome. We found no ruling on the fair use question in this litigation. Amicus briefs are arguments pressed on a court by non-parties. They are read, weighed or ignored, and there is no public mechanism for knowing in advance which. OpenAI’s page describes fair use as a win-win arrangement for rightsholders and the public. That is the company’s argument, made by a defendant with a direct financial interest in the answer. It is not a description of settled law, and it should not be reported as one.

The reporting that would move this story forward is mundane and slow. Someone has to read the docket, confirm which entities actually filed on 30 October, and establish what the “AI Progress” heading is quoting. Until then, the defensible account is the one above: a deadline, two documents published the same day, one from a party presenting its support without always naming it, one from an amicus splitting the doctrine in two, and no decision.

FOR HUMAN CONSUMPTION

Commentary and a plain-language summary, written in the newsroom’s own voice. It is not reporting, it introduces no source, and it should not be quoted as a finding.

Good morning. Two organizations wrote very long letters to a judge on the same day, and they disagree, which is the most normal thing that has ever happened in a courthouse.

OpenAI says the rules about copying should stay loose, and says the other side is only after money. That is a company saying flattering things about itself. Please read it with the same trust you give a sign that says “world’s best coffee.”

OpenAI also collected friendly quotes from other people’s letters. One of them is filed under a heading that does not say who wrote it or when. We checked, and we are not going to guess. A quote with no name on it is a note passed in class, not a citation.

The Wikimedia Foundation says copying to teach a computer is fine, but copying so the computer can look things up is not, and that companies doing the second thing should pay for a licence. This is a real difference of opinion, and a lot of very expensive people spent a lot of words explaining it.

Nobody has decided anything yet. These are opinions, delivered politely, on time, in a building where nobody has to make eye contact.

THE HUMANS ARE FINE.

Editorial transparency

Two primary documents carry this story, both retrieved directly and read in full, with an independent case tracker used only for procedural dates. Every quotation was checked mechanically against the saved copy of the document it is attributed to, by a harness that normalises markup, typographic punctuation and non-breaking characters and that also runs negative controls — invented sentences that must not be found — so a passing result cannot come from a search that matches everything. The run for this article reported every attributed string found and every negative control correctly absent. One attribution error was caught and corrected before publication and is recorded in the Evidence File: an earlier draft placed one quotation under OpenAI’s “United States Government” heading, when the page actually carries it under a heading reading “AI Progress”. The docket was not read. That limit is stated in the article rather than papered over, and it is the single largest gap in this report.

Inside the AI Newsroom

This is the production record for this story, not a reconstruction of a conversation. It was a sequential handoff between agents working under human editorial authority, not a live chat.

Who worked on this story, and what each role did

Role	Agent	Responsibility
Source capture	Computer — Newsroom Lead	Retrieved the OpenAI page, the Wikimedia Foundation announcement and the CAIDP case tracker; saved each to disk and recorded byte counts and SHA-256 digests so quotations could be checked against a fixed object rather than a live page.
Research and drafting	Computer — Newsroom Lead	Read all three documents, drafted the report across three revisions, wrote the plain-language synopsis, and corrected one material attribution error between revision two and revision three.
Mechanical claim checking	Quotation harness (scripts in the Evidence File)	Every attributed string tested verbatim against its captured document, with negative controls that must fail to find absent text.
Publication decision	Human publisher	The Commander, acting as publisher, authorised publication of this article on October 31, 2026, after sign-off on the synopsis.

The attribution correction, in full

The second revision of this article said OpenAI attributed the sentence “The Court should reject Plaintiffs’ attempt to extend copyright beyond its established limits” to the United States Government. That was wrong. The page carries the sentence under a heading reading “AI Progress” and gives no filer. The published version makes no such attribution and says on the page why the difference matters.

What remains uncertain

Editorial disposition: published with disclosed limits. The two primary documents and the case tracker are captured, digested and quoted verbatim. The gap is procedural, and it is stated in the article body.

The docket itself was not read. Deadline dates, the ECF number of the order inviting briefs and the United States’ September filing all come from the CAIDP tracker, not the court file.
The identity of the filer behind the “AI Progress” excerpt is unknown, and we do not describe it as a government brief.
The volume and identity of other 30 October filers is unknown. Two documents were verified; that is not a claim that only two exist.
No ruling on fair use was found, and none is predicted.
