Arcjet 首席执行官 David Mytton 与 a16z 合伙人 Joel de la Garza 共同探讨了管理网站及网络应用访问权限与操作行为的日益复杂性。核心挑战在于判断自动化流量究竟来自恶意行为者与麻烦的机器人,还是代表真实客户购买产品的 AI 代理。
Joel 与 David 深入分析了如何在分析每个请求时不增加延迟,以及边缘端更快的推理如何为欺诈防护、内容过滤乃至广告技术开辟新可能。
讨论主题包括:
- 为何传统威胁分析无法适用于 AI 驱动的网络
- 全上下文安全检查的必要性
- 如何实现亚秒级、高性价比的推理
- 每次访问背后潜藏的多种行为者与操作类型
正如 David 所言,降低推理成本是让应用能够基于完整上下文窗口(即关于用户、会话及应用的所有已知信息)采取行动的关键。

America’s defense, energy, manufacturing, and robotics booms are increasingly becoming one story: the rebuilding of the country’s industrial base. This year’s AD50 highlights the companies building across that stack, from critical materials and factories to the systems they ultimately power.
a16z’s Erin Price-Wright and Connor Love join Elena Burger to unpack what has changed. They discuss how defense demand can help finance manufacturing capacity that ultimately serves much larger commercial markets, why AI is changing the economics of American factories, and how a new generation of founders is applying lessons from SpaceX, Tesla, Anduril, and Palantir to mining, energy, manufacturing, and defense.
They also make the case that these companies are no longer simply important to America. With private capital increasingly willing to fund physical infrastructure and production before government demand is guaranteed, they can become some of the most valuable companies in the world.

Mark Cuban thinks AI could transform healthcare, but it won’t fix opaque prices and broken incentives on its own. His starting point for employers: run every benefits contract through AI and ask where you’re getting ripped off.
Mark joins a16z General Partner Julie Yoo and Erik Torenberg to discuss what he’s learned building Cost Plus Drugs, why trust is its core product, and how greater transparency could put pressure on healthcare costs.
They also explore where AI can help, what personalized medicine could look like, how the role of doctors may change, and why Mark believes founders should use AI to learn, not as an excuse to stop thinking.

What should school look like if AI can help students learn dramatically faster? Alpha School principal Joe Liemandt argues the answer isn’t to fill the extra time with more academics, but to redesign school around the skills traditional classrooms struggle to teach: agency, teamwork, entrepreneurship, communication, and doing hard things.
Joe joins Erik Torenberg and Horowitz Andreessen Academy co-founder Gagan Biyani to discuss Alpha’s model, where students spend two hours a day on core academics and the rest developing real-world skills through projects. They explore what that approach can teach higher education, why motivation may matter more than curriculum, and how HAA is applying similar principles to college-age students by putting building, relationships, and real-world experience at the center of the learning experience.
They also discuss what parents need to believe before choosing a new educational model, why Joe expects AI to drive an explosion in entrepreneurship, and why the most important question for students may not be which field is safest from AI, but what they care enough about to build.

AI agents are approaching a point where they can use computers faster than expert humans, turning the user interface itself into a universal way for AI to interact with software. OpenAI’s Ari Weinstein and James Sun argue that computer use is now entering its scaling moment, as better models, faster execution, and stronger safety controls make agents practical for more consumer and enterprise work.
Ari and James join a16z’s Seema Amble and Fabrizio Serafini to explain how computer-using agents are already navigating legacy ERPs, reconciling financial data, handling procurement, and operating software without APIs or custom integrations. They also discuss why the harness around the model can matter as much as model intelligence, how enterprises can set deterministic guardrails around agent behavior, and why computer use could simultaneously extend the life of legacy software and accelerate the arrival of new AI-native applications.
Looking ahead, they make the case for a more proactive and fluid relationship with computers, where agents work in the background, collaborate with users in real time, and increasingly adapt to us rather than requiring us to learn how to use them.

Amazon expects to spend roughly $220 billion in CapEx in 2026, yet CEO Andy Jassy says the company is still leaving meaningful AI demand on the table. He believes the buildout could ultimately help make AWS a $1 trillion annual run-rate business.
Andy joins a16z co-founder Ben Horowitz and Erik Torenberg to discuss why AI demand is growing so quickly, how Amazon decides how much infrastructure to build, and why lower inference costs could unlock broader enterprise adoption.
They also discuss how AI is reshaping Amazon itself, from smaller teams building products faster to reimagining Alexa, and why Andy sees cybersecurity, human judgment, and critical thinking as increasingly important in the AI era.

a16z is expanding a16z crypto into a16z Frontier, a broader mandate to back founders building at the edges of what's possible. Chris Dixon joins Marc Andreessen, Ben Horowitz, and Erik Torenberg to explain why founders should increasingly ask not “is this too ambitious?” but “is this ambitious enough?” — and how AI could pull decades of technological progress forward across hardware, robotics, entertainment, science, and entirely new forms of media.
They also explore the coming internet of AI agents, why open source matters as AI becomes more powerful, and why some of the most important companies of the next decade may combine technologies and business models that previously belonged in separate categories.

More than 300 million people use ChatGPT for health and wellness questions each week. OpenAI’s Karan Singhal thinks that’s only the beginning: the longer-term goal is AI that can help people navigate their health proactively, while making trustworthy medical intelligence dramatically more accessible.
Karan joins a16z Partner Jay Rughani to explain why OpenAI trains healthcare expertise directly into its general-purpose frontier models, how it works with hundreds of medical experts to evaluate safety and disagreement, and why the company sees AI as a complement to doctors rather than a replacement for medical care. They also discuss integrations with Epic, AI copilots for clinicians, and what happens as personal agents begin navigating appointments, health records, and other fragmented parts of the healthcare system.
Looking further ahead, Karan makes the case that the cost of medical intelligence could continue to fall dramatically, allowing AI to act as a safety net for patients and clinicians, surface insights from years of health data, and potentially accelerate the discovery and validation of new treatments.

Jean-Denis Greze was CTO of Plaid. His next startup, an AI tax product for small businesses, made nearly $1M in its first year and was on track for $2.5M to $3M. He shut it down anyway.
The reason: in the age of AI, it was never going to be venture scale. Incumbents could use the same technology to automate tax prep for their existing customers faster than a startup could win market share. Tax is also sold once a year, so he had about a one-month window to pivot before the door closed.
The pivot became Town, an AI assistant that works from your email and calendar. It found product-market fit fast enough that Ben Horowitz messaged a16z partner Alex Rampell to say it “changed my life,” without knowing whose company it was.
In this episode, Alex and Jean-Denis cover:
- Why a profitable business can still be the wrong business to build
- How to know when to kill something that’s working
- Why Town competes with OpenAI and Anthropic, the companies it buys its tokens from
- Why the “forward deployed engineer” model gets worse as AI gets better
- How a $1/month AI routine can save a restaurant thousands
- What agents mean for Amazon, advertising and the future of shopping

AI can write production code in minutes. But can it debug and operate that code when something goes wrong? Grepr CEO Jad Naous argues that running real-world systems is a fundamentally harder challenge, with unpredictable workloads, failures, and countless possible states.
Jad joins a16z General Partner Martin Casado to discuss how coding agents have transformed engineering inside his 10-person team, including projects that once took six months and now take roughly 10 days.
They also explore whether AI can troubleshoot production systems by detecting changes, forming hypotheses, and running experiments, and why the best engineers may be gaining the most leverage from AI.

What happens when AI agents start spending your money? VGS' Terry Angelos argues that agentic commerce will need new payment infrastructure that gives AI the ability to transact without sacrificing the protections consumers expect.
Terry joins a16z General Partner Alex Rampell to discuss the emerging wallet wars, how agentic tokens could enable secure purchases, and what happens when an AI buys the wrong thing.
They also explore why merchants may resist agentic commerce, how AI could change credit card rewards and subscriptions, and who controls the customer relationship when agents make purchasing decisions on our behalf.

a16z Partner Lisha Li sits down with AI researcher and Trillium founder Nathan Lambert to ask how durable the gap really is between frontier AI labs and open models.
Nathan argues that OpenAI and Anthropic have structural advantages in compute, capital, and the ability to pioneer new training paradigms, but open-model labs, particularly in China, have proven remarkably capable of following close behind. They unpack how much of that comes from distillation versus technical talent, why compute remains a major constraint, and how data, RL environments, and post-training are increasingly shaping model progress.
They also discuss Nathan’s new nonprofit research lab, Trillium, and its plans to open up parts of AI research that are increasingly difficult to study from the outside. That includes releasing RL environments and documenting how AI is actually being used to automate AI research, with the goal of demystifying recursive self-improvement and giving researchers and policymakers a clearer picture of what frontier systems can and cannot do.

a16z General Partner Martin Casado sits down with MakerMaker.AI co-founders Dhaval Adjodah and Owen He to unpack recursive self-improvement, or RSI, and separate the increasingly popular term from what it would actually mean for an AI system to improve itself.
Dhaval and Owen distinguish true RSI from simply using AI to automate pieces of AI development. Their goal is a closed loop where the system being improved is also doing the improving, across components including models, harnesses, and eventually more of the AI stack. They explain why closing that loop still doesn’t guarantee runaway “takeoff,” and why measuring real progress requires accounting for both capability gains and the resources required to achieve them.
They also share what they’re seeing in their own research, including early signs that self-improving systems can increase performance while improving efficiency. And they dig into the practical challenges of proving those gains are real, from variance and reward hacking to the enormous difficulty of distinguishing genuine improvement from noise.

a16z's Raghu Raghuram and Guido Appenzeller sit down with Playground Global General Partner and former Intel CEO Pat Gelsinger to discuss the next wave of semiconductor innovation and the physical constraints shaping the AI buildout.
Drawing on his experience designing Intel's 386 and 486 processors, Pat explains how AI could transform chip design, but also why faster design alone won't solve the industry's biggest problems. They examine the bottlenecks in manufacturing, memory bandwidth, advanced packaging, and power, and why today's explosion of specialized AI chips may eventually consolidate around a smaller number of architectures.
They also discuss the potential for new memory technologies, the shift from copper to optical networking, and why energy capacity could become a major constraint on AI growth. Finally, they revisit Pat's VMware years to ask what virtualization might look like when infrastructure is built for agents rather than humans.
