What to know:

Senator Cynthia Lummis introduced the RISE Act of 2025 to clarify liability for AI used by professionals and mandate transparency from developers.
The bill requires AI developers to release model cards detailing AI systems' data sources, use cases, and limitations.
The RISE Act stops short of requiring AI models to be open source, but mandates updates and justifications for withheld proprietary information.
Senator Cynthia Lummis (R-WY) has introduced the Responsible Innovation and Safe Expertise (RISE) Act of 2025, a legislative proposal designed to clarify liability frameworks for artificial intelligence (AI) used by professionals.

The bill could bring transparency from AI developers – stoping short of requiring models to be open source.

In a press release, Lummis said the RISE Act would mean that professionals, such as physicians, attorneys, engineers, and financial advisors, remain legally responsible for the advice they provide, even when it is informed by AI systems.

At the time, AI developers who create the systems can only shield themselves from civil liability when things go awry if they publicly release model cards.

The proposed bill defines model cards as detailed technical documents that disclose an AI system's training data sources, intended use cases, performance metrics, known limitations, and potential failure modes. All this is intended to help help professionals assess whether the tool is appropriate for their work.

"Wyoming values both innovation and accountability; the RISE Act creates predictable standards that encourage safer AI development while preserving professional autonomy," Lummis said in a press release.

"This legislation doesn't create blanket immunity for AI," Lummis continued.

However, the immunity granted under this Act has clear boundaries. The legislation excludes protection for developers in instances of recklessness, willful misconduct, fraud, knowing misrepresentation, or when actions fall outside the defined scope of professional usage.
