STIPULATION AND [PROPOSED] ORDER EXTENDING DEADLINE TO FILE
JOINT LETTER BRIEF REGARDING MIDJOURNEY’S END-USE ART TRAINING DATASETS
Pursuant to Local Rules 6-2 and 7-12, Plaintiffs Sarah Andersen, Karla Ortiz, Grzegorz Rutkowski,
Gregory Manchess, Gerald Brom, Jingna Zhang, Julia Kaye, and Adam Ellis (“Plaintiffs”) and Defendant
Midjourney Inc. (“Midjourney”) (collectively, the “Parties”), by and through their respective counsel,
hereby stipulate and request as follows:
WHEREAS, on May 14, 2026, the Court ordered that to the extent that the Parties are unable to
reach a resolution on Midjourney’s production of end-use datasets, they should file a joint letter brief
regarding the issue no later than Thursday, June 4, 2026, ECF No. 555;
WHEREAS, on June 5, 2026, the Court ordered that the deadline to file a joint letter brief with the
Court regarding Midjourney’s end-use training datasets will be Monday, June 15, 2026, ECF No. 583,
pursuant to the Parties’ joint stipulation, filed June 4, ECF No. 582;
WHEREAS, the Parties have been negotiating in good faith and have come to substantial agreement
regarding Midjourney identifying and producing the final versions of datasets used to train Midjourney’s
main model versions;
WHEREAS, Plaintiffs have also identified certain “Art” and “Artist” specific training datasets in
Midjourney’s documents that Plaintiffs believe were used to fine tune and train its models and auxiliary
models, and have asked for the identification and production of those datasets along with other the relevant
end-use training data;
WHEREAS, Midjourney disputes Plaintiffs’ characterization and argues that the identification and
production of such art and artist-specific datasets are outside the scope of relevant discovery in this matter,
and Plaintiffs argue such datasets are relevant to rebutting “fair use”;
WHEREAS, the Parties previously agreed to postpone final resolution of this issue, and to
determine whether to burden the Court with another joint latter brief, until after the Court ruled on the
Parties’ Joint Letter Brief regarding the production of source code underlying Midjourney’s “overfit” filter
and its style reference model, ECF No. 531, filed May 1, 2026, for which the Parties advanced similar
arguments;
WHEREAS, the resolution of ECF No. 531 continues to be forthcoming from the Court;

STIPULATION AND [PROPOSED] ORDER EXTENDING DEADLINE TO FILE
JOINT LETTER BRIEF REGARDING MIDJOURNEY’S END-USE ART TRAINING DATASETS
WHEREAS, to enable the Parties to complete their discussions regarding art and artist end-use
training datasets, and in the hope of avoiding unnecessary motion practice, the Parties have agreed, subject
to the approval of the Court and to the extent that any dispute remains, to extend the deadline to file a joint
letter brief with the Court regarding the identification and production of Midjourney’s end-use art and artist
training datasets until Tuesday, June 23, 2026;
WHEREAS, an extension to the deadline to file a joint letter brief regarding Midjourney’s end-use
art and artist-specific datasets would have no other effect on the current schedule for the case;
NOW, THEREFORE, IT IS HEREBY STIPULATED AND AGREED, by and between the Parties,
through their undersigned counsel, subject to the approval of the Court, that the deadline to file a joint letter
brief with the Court regarding Midjourney’s end-use art and artist training datasets will be Tuesday, June
23, 2026.
PURSUANT TO STIPULATION, IT IS SO ORDERED.
Dated: June 17, 2026 ___________________________________
Honorable Lisa J. Cisneros
