    How Does AI Perform in the Real World?

    As AI takes on more complex work, people need ways to understand how well it performs. Does a model follow instructions? Does it complete the task? How does one model compare to others? In this episode, Matt Perault speaks with Arena cofounder and CEO Anastasios Angelopoulos about evaluating AI through real-world use. What began as a research project at UC Berkeley comparing chatbot responses has grown into a leading platform for measuring how models perform as people use them to get work done. They discuss Arena’s Alignment Index, a measure of how often models misbehave, for example by acting without permission or reporting work as done when it isn’t. They explore what those measurements can—and cannot—tell us about AI’s capabilities and risks, and how competition to improve an Index score can encourage model developers to improve. The conversation also examines why evaluation methods need to keep evolving, and why public policy should leave room for new evaluators to compete rather than locking in a handful of approved methods or incumbents. For policymakers, better evaluations can inform judgments about capabilities and risk. For businesses, they can help guide model selection. And for builders, competition creates room to develop new ways of measuring AI as the technology advances. Enjoy. Topics covered: 02:06: Arena’s origins from chatbot comparisons to real-world work 06:06: Why independent evaluation matters 07:06: What makes an evaluator neutral? 10:06: Ecological validity and how a testing environment shapes measurement 14:06: Evaluating longer conversations and complex tasks 15:06: The Arena Alignment Index 18:06: How misalignment appears in real use 20:06: Separating measurement from policy debates 22:06: What evaluations can tell us about acceptable risk 26:06: Breaking down broad risks into measurable behaviors 28:06: Policy choices for the evaluation ecosystem 29:06: Why evaluation frameworks need room to evolve 32:06: Customer demand and competition as incentives 36:06: Building trust when rankings are contested 39:06: What Arena plans to measure next 40:06: What Arena’s leaderboards show about model competition today 43:06: Evaluating open and proprietary models Resources: Follow Anastasios on X: https://x.com/ml_angelopoulos Follow Arena on X: https://x.com/arena Learn more about the Arena Alignment Index: https://arena.ai/blog/ai-alignment-index Follow Matt Perault on X: https://x.com/MattPerault Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ The content here is for informational purposes only, should not be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security, and is not directed at any investors or potential investors in any a16z fund.

    How AI Is Changing the Practice of Law

    AI is changing how lawyers review contracts, conduct research, and serve their clients. As more of that work shifts to AI agents, lawyers face a new challenge: learning to direct those tools and evaluate their output while remaining accountable for the results. In this episode, Harvey’s chief legal officer John LaBarre joins Matt Perault to discuss what that transition looks like in practice. They explore how Harvey’s own legal team uses AI, how greater efficiency could make legal help more affordable and accessible, and what those changes could mean for the job market lawyers. They also examine how professional rules shape who can benefit from the technology and discuss competition between AI applications and model providers. A recent California legislative example highlights how policymakers can strengthen protections for people seeking legal help while preserving access to legal AI tools. Topics covered: 00:00: Intro 01:37: What Harvey does: From legal research to AI agents 03:57: Lawyers’ responsibilities, confidentiality, and trust in the age of AI 07:54: Access to justice and the limits of professional licensing 10:53: How Harvey’s legal team helps shape the company’s product 13:04: Helping lawyers adopt new tools and ways of working 14:59: Building an AI-native legal team 17:58: Understanding AI’s limitations and applying professional judgment 21:41: “Human on the hook”: Accountability for AI-assisted work 24:00: Legal fees, efficiency, and the future of the billable hour 27:34: Barriers to adoption and lawyers’ ethical duties around technology 30:02: Preparing future lawyers to direct and evaluate AI agents 33:50: Why greater efficiency could expand demand for legal work 36:57: How Harvey chooses among AI models 38:20: Partnering and competing with model providers 41:52: California’s SB 574 and the importance of clear definitions in policymaking Resources: Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ Follow John LaBarre on LinkedIn: https://www.linkedin.com/in/labaj/ Follow Harvey on X: https://x.com/harvey Follow Matt Perault on X: https://x.com/MattPerault The content here is for informational purposes only, should not be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security, and is not directed at any investors or potential investors in any a16z fund.

    Turning America’s AI Progress Into a Manufacturing Advantage

    A better medical device or more capable robot can be held up for months by something surprisingly fundamental: its printed circuit board. These components sit inside nearly every modern electronic product, yet designing, testing, and manufacturing them remains a bottleneck. The U.S. is heavily dependent on manufacturing capacity concentrated in Asia for these critical parts, which means American hardware innovation is beholden to business and geopolitical dynamics outside its borders. In this episode, Davide Asnaghi, cofounder and CEO of Diode, joins Matt Perault to explain how his company combines AI-powered circuit board design with in-house manufacturing. Davide describes how connecting software and electrical engineering directly to production can shorten development cycles, improve quality, and make building advanced hardware in the U.S. more competitive. The conversation explores an American manufacturing strategy built around the country’s strengths in software and AI. Davide explains what it looks like in practice today at Diode’s Brooklyn factory, where engineers write code and run the production line under one roof. Davide and Matt discuss how automation can help workers oversee more production and exercise greater judgment, why domestic supply chains require a connected ecosystem of companies, and how durable policy can give founders the confidence to invest in this critical sector. Topics covered: 01:22: Intro: Turning American AI progress into manufacturing capacity 02:15: What Diode does: Connecting design and manufacturing with AI 03:34: Why circuit boards are a bottleneck for hardware innovation 08:51: The circuit board failure that inspired Diode 11:09: Why Asia currently leads in circuit board manufacturing 14:27: Building an American manufacturing strategy around software and AI 17:04: How AI accelerates machine programming and production 18:25: Human oversight and new opportunities for manufacturing workers 25:21: Improving quality and detecting manufacturing defects 27:29: Scaling from prototypes to production 28:44: Building a connected US manufacturing ecosystem 30:45: Why policy certainty matters for manufacturing investment 33:02: How startups compete and bring new capacity online 35:36: Inside Diode: Engineers who write code and run the factory 38:34: The economics of scaling manufacturing in America 41:18: The promise of bringing better products to consumers faster Resources: Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ Follow Davide on X: https://x.com/davideasnaghi Follow Diode on X: https://x.com/diodeinc Follow Matt Perault on X: https://x.com/MattPerault The content here is for informational purposes only, should not be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security, and is not directed at any investors or potential investors in any a16z fund.

    Measuring AI: What Policymakers Can Learn from Benchmarks

    AI benchmarks are becoming increasingly central to policy debates. But much of the value of these benchmarks depends on how they are built: what they measure, who develops and runs them, and how quickly they evolve alongside the models they evaluate. In this episode, Matt Perault speaks with Rayan Krishnan, cofounder and CEO of Vals, and Glenn Parham, head of public sector, about their work building AI evaluation tools and partnerships for industry and government. They discuss why static tests quickly become obsolete, why credible evaluations require deep domain expertise and independent testing, and how a growing market of evaluators is moving the field beyond “evaluations by vibes” toward more rigorous, data-driven evidence for policymakers. Topics covered: 00:00: Intro 02:00: What is Vals? 05:00: Keeping benchmarks current 08:00: New strides in AI evaluation 11:00: Measuring AI’s cyber capabilities 14:00: Why government needs independent evaluation 21:00: The growing market for AI benchmarks 26:00: What benchmarks can—and cannot—measure 29:00: Building trust in AI benchmarks 35:00: Why AI performance varies across domains and tasks 37:00: Bringing AI evaluation to government 41:00: From “evaluations by vibes” to better evidence Resources: Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ Follow Matt Perault on X: https://x.com/MattPerault Follow Rayan Krishnan on X: https://x.com/RayanKrishnan Follow Glenn Parham on X: https://x.com/glenn__parham Follow Vals.ai on X: https://x.com/ValsAI The content here is for informational purposes only, should not be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security, and is not directed at any investors or potential investors in any a16z fund.

    AI's Data Access Question

    AI is reopening a core question from the development of the web: how to preserve the freedom to learn while giving publishers meaningful control over how their works are made available. In this episode, Matt Perault is joined by Derek Slater, cofounder of Proteus Strategies and an expert on information access, copyright, and free expression, to examine this question and explain why it matters for the future of AI. The web worked because people could access, read, analyze, and build on lawfully available information. Standards like robots.txt helped manage the balance between openness and control at scale, giving publishers a way to express preferences without requiring every builder to negotiate permission website by website. AI is now testing that equilibrium. Some proposals would restrict not only unlawful access, like when AI developers circumvent paywalls to get data, but also lawful learning from public information through expanded copyright theories, terms of service, technical barriers, or licensing requirements. Derek and Matt separate those issues, including the difference between training models on lawfully accessed data, producing infringing outputs, using AI tools to summarize content a user can already access, and breaking through access controls. For Little Tech, this question is fundamental. Access to data operates as a form of startup capital, allowing new companies to develop products and compete. But if AI companies can’t learn without negotiating expensive licenses or if large pools of data are entirely off limits to AI learning, then only the biggest, most-resourced companies will be able to survive. Topics covered: 00:00: Introduction 01:45: The freedom to learn and AI data access 04:16: What the early web can teach us about openness, control, and contested norms 08:48: How robots.txt helped publishers express preferences at scale 11:43: Why voluntary standards worked for search engines and publishers 13:50: How freedom to learn applies beyond technology and copyright debates 16:02: The publisher POV on traffic, monetization, and value exchange 18:36: Why AI agents are raising new questions about user control 20:36: The difference between protecting publishers and limiting lawful AI-assisted reading 21:42: How copyright law applies to AI training inputs and model outputs 28:08: How contracts and terms of service can attempt to restrict lawful learning 31:12: The limits of “learning” as a defense 33:53: How licensing markets are evolving around data access and AI outputs 37:12: Technical collaboration and the future of robots.txt-style standards for AI 39:43: Why data access is a Little Tech issue 42:25: Public policy guidance for preserving the freedom to learn 45:29: Closing thoughts Disclosure: Derek Slater has previously provided consulting support to Andreessen Horowitz.

    Marc Andreessen on Betting on America

    Marc Andreessen joins Navin Girishankar, president of the economic security and technology department at the Center for Strategic and International Studies (CSIS), for a wide-ranging conversation on artificial intelligence, productivity growth, national competitiveness, and America’s technological future. In their conversation, Marc argues that while AI has already begun reshaping the economy, the largest impacts are still ahead. He explores how AI could dramatically expand access to intelligence, improve productivity, and transform industries ranging from healthcare and education to law and software development. At the same time, he warns that many of the biggest barriers to progress are not technological but institutional, driven by policy choices and infrastructure constraints. The discussion also covers the global AI race, U.S.-China competition, export controls, energy, reindustrialization, and the role of government in fostering innovation. Along the way, Marc shares his views on technological progress and why he believes America still has an opportunity to lead the next wave of economic growth. Topics covered: 00:00: Introduction: acceleration, transition, and policy 00:02: The AI boom: optimism versus utopianism 00:04: AI as an intelligence equalizer 00:08: Education and institutional reform 00:13: Productivity by sector: blue sectors and red sectors 00:18: AI infrastructure constraints 00:22: Tariffs and behind-the-border constraints 00:26: Model export controls and the Mythos case 00:33: The technological imperative and policy tradeoffs 00:37: Lessons from Netscape and encryption export controls 00:43: U.S.-China competition, open source AI, and civil-military fusion 00:50: Public sector reform and government capability 00:53: AI for public policy 00:55: Industrial renaissance and American Dynamism 1:00: Closing thoughts Resources: Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ Follow Marc Andreessen on X: https://x.com/pmarca Follow Navin Girishankar on X: https://x.com/ngirishankar Follow CSIS on X: https://x.com/CSIS Please note that the content here is for informational purposes only; should NOT be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security; and is not directed at any investors or potential investors in any a16z fund. a16z and its affiliates may maintain investments in the companies discussed.

    The Political Economy of Little Tech

    Policymakers often say they want to support startups. Republicans say it. And Democrats say it. But despite repeatedly saying they support startups, policymakers often propose rules that make it harder for those startups to build and compete. In this episode, Collin McCune, head of government affairs, joins Matt Perault, head of AI policy at a16z, to discuss the political economy of Little Tech: the structural dynamics that produce a policy process that so consistently rewards the companies with the most time, money, and access. In sum, it favors Big over Little. They also talk about the impact of the political economy of Little Tech on consumers. When regulation locks in incumbents, people end up with fewer choices, products that are lower quality and less innovative, and higher costs. Topics covered: 01:00 The paradox of policymaker support for startups 03:30 Why startups are underrepresented in the policy process 05:40 How feedback on bills works in practice 07:30 Why “industry” feedback often misses Little Tech 09:45 The costs of showing up late to policy debates 12:00 Audits, impact assessments, and invisible compliance costs 15:30 How large policy teams create incumbent advantage 18:30 Why audits can be harder than they look 21:15 Policy ideas to better account for startup costs 23:45 Why startup competition matters for everyday people 25:45 Bright spots for Little Tech in Washington 27:30 Lessons from Dodd-Frank and the risk of repeating them in tech Resources: Subscribe to the a16z AI Policy Brief: https://a16zpolicy.substack.com/ Follow Matt Perault: https://x.com/MattPerault Follow Collin McCune: https://x.com/Collin_McCune Please note that the content here is for informational purposes only; should NOT be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security; and is not directed at any investors or potential investors in any a16z fund. a16z and its affiliates may maintain investments in the companies discussed.
