Program Summary

The CLE will examine California Assembly Bill 2013, the Generative Artificial Intelligence Training Data Transparency Act, which goes into effect on January 1, 2026. The presentation will cover the law's main provisions, including its scope and coverage and the requirement that covered developers post documentation, including high-level summaries of training data on their websites, who qualifies as a covered developer, and what constitutes a substantial modification triggering new disclosure obligations. Attendees will learn about the law's gaps, including the absence of explicit trade secret or other protections, prescribed disclosure formats, or explicit enforcement mechanisms and the practical compliance issues that may arise. The presentation will situate AB 2013 within the broader patchwork of U.S. state AI legislation, including other proposals for model-training data disclosures, as well as other types of AI transparency measures enacted in California and other jurisdictions.

Key topics to be discussed:

  • Scope and coverage of A.B. 2013
  • A.B. 2013’s substantive requirements
  • Context for A.B. 2013 in the broader AI regulatory framework in California and the U.S.

  • 12:00 pm – 1:00 pm Central

Will Weaver | Jenner & Block LLP

Will Weaver represents clients facing challenges at the intersection of investigations, regulation and litigation, helping clients respond to sensitive government inquiries and high-stakes litigation. Will has helped major technology companies navigate a fast-changing regulatory environment by evaluating challenges to proposed legislation and regulations, preparing top executives for congressional hearings and defending lawsuits involving current political subjects including the Communications Decency Act. He counsels clients on pending legislation and regulations. Lately, Will’s practice has focused on assisting clients in navigating new state, federal, and international regulations on the development and use of AI.

Will has represented clients in numerous congressional investigations and hearings, including preparing witnesses for hearings before committees of the US Congress, the European Parliament and US state legislatures. He has prepared top executives for hearings before the House and Senate Judiciary Committees and has advised political nominees in their personal capacity on their nominations and confirmation hearings. Will has represented clients in criminal inquiries and, in his active appellate practice, has represented clients before the US Supreme Court and US courts of appeals. Recently, he won a resounding victory before the US Court of Appeals for the Third Circuit on behalf of a client seeking asylum and relief under the Convention Against Torture. He also has experience representing clients in complex, high-stakes global disputes.

Will’s active pro bono practice has included representing public advocacy organizations in a constitutional challenge to a state juvenile justice system, asylum seekers in proceedings before an immigration judge and a criminal defendant challenging a search warrant on appeal.
