On July 31, 2025, the Trump administration released “Winning the Race: America’s AI Action Plan.” CSET has broken down the Action Plan, focusing on specific government deliverables. Our Provision and Timeline tracker breaks down which agencies are responsible for implementing recommendations and the types of actions they should take.

This blog examines 18 AI-related laws that California enacted in 2024, 8 of which are explored in more detail in an accompanying CSET Emerging Technology Observatory (ETO) blog. This blog also chronicles California’s history of regulating AI and other emerging technologies and highlights several AI bills that have moved through the California legislature in 2025.

To protect Europeans from the risks posed by artificial intelligence, the EU passed its AI Act last year. This month, the EU released a Code of Practice to help providers of general purpose AI comply with the AI Act. This blog reviews the measures set out in the new Code’s safety and security chapter, assesses how they compare to existing practices, and what the Code’s global impact might be.

CSET's Jacob Feldgoise and Hanna Dohmen outline China's market share gains in semiconductor manufacturing equipment, based on data from CSET ETO's updated Supply Chain Explorer.

Effectively evaluating AI models is more crucial than ever. But how do AI evaluations actually work? Our explainer lays out the different fundamental types of AI safety evaluations alongside their respective strengths and limitations.

Since 2022, U.S. export controls have restricted the highest-performing AI chips from being exported to China. The Biden administration likely did not intend to control CPUs (i.e., general-purpose processors) with these restrictions. However, CPUs are increasingly subject to export controls because chip designers are incorporating specialized elements for AI computation into CPUs. In this blog post, we discuss the implications of controlling AI-capable CPUs and make recommendations for the Bureau of Industry and Security (BIS) at the U.S. Department of Commerce.

The European Union's Artificial Intelligence Act has officially come into force today after more than five years of legislative processes and negotiations. While marking a significant milestone, it also initiates a prolonged phase of implementation, refinement, and enforcement. This blog post outlines key aspects of the regulation, such as rules for general-purpose AI and governance structures, and provides insights into its timeline and future expectations.

Large language models (LLMs), the technology that powers generative artificial intelligence (AI) products like ChatGPT or Google Gemini, are often thought of as chatbots that predict the next word. But that isn't the full story of what LLMs are and how they work. This is the third blog post in a three-part series explaining some key elements of how LLMs function. This blog post explains how AI developers are finding ways to use LLMs for much more than just generating text.

Large language models (LLMs), the technology that powers generative artificial intelligence (AI) products like ChatGPT or Google Gemini, are often thought of as chatbots that predict the next word. But that isn't the full story of what LLMs are and how they work. This is the second blog post in a three-part series explaining some key elements of how LLMs function. This blog post explores fine-tuning—a set of techniques used to change the types of output that pre-trained models produce.

The October 30, 2023, White House executive order on artificial intelligence requires companies developing the most advanced AI models to report safety testing results to the federal government. CSET Horizon Junior Fellow Thomas Woodside writes that these requirements are a good first step towards managing uncertain risks and Congress should consider codifying them into law.
