In this episode, a16z General Partner Martin Casado sits down with Sujay Jayakar, co-founder and Chief Scientist at Convex, to talk about his team’s latest work benchmarking AI agents on full-stack coding tasks. From designing Fullstack Bench to the quirks of agent behavior, the two dig into what’s actually hard about autonomous software development, and why robust evals—and guardrails like type safety—matter more than ever. They also get tactical: which models perform best for real-world app building? How should developers think about trajectory management and variance across runs? And what changes when you treat your toolchain like part of the prompt? Whether you're a hobbyist developer or building the next generation of AI-powered devtools, Sujay’s systems-level insights are not to be missed.Drawing from Sujay’s work developing the Fullstack-Bench, they cover:Why full-stack coding is still a frontier task for autonomous agentsHow type safety and other “guardrails” can significantly reduce variance and failureWhat makes a good eval—and why evals might matter more than clever promptsHow different models perform on real-world app-building tasks (and what to watch out for)Why your toolchain might be the most underrated part of the promptAnd what all of this means for devs—from hobbyists to infra teams building with AI in the loopLearn More:Introducing Fullstack-BenchFollow everyone on X:Sujay JayakarMartin Casado

Automating Developer Email with MCP and Al Agents
In this episode of AI + a16z, Resend founder and CEO Zeno Rocha sits down with a16z partner Yoko Li to discuss:How generative AI — powered by agents and, now, MCP — is reshaping the email experience for developers, as well as the overall world of programming. Zeno's obsession with developer experience has evolved into designing for "agent experience" — a new frontier where LLM-powered agents are not only building products but also operating within them. How email, one of the most ubiquitous tools for developers and end users alike, is being reimagined for a future where agents send, parse, and optimize communication. What it means to build agent-friendly APIs. The emerging MCP protocol, and how AI is collapsing the creative loop for prosumers and developers alike.Learn more:What is AX (agent experience) and how to improve itA deep dive into MCP and the future of AI toolingDracula themeFollow everyone on X:Zeno RochaYoko Li

Agent Experience: Building an Open Web for the AI Era
In this episode of AI + a16z, Netlify CEO and Cofounder Matt Biilmann joins a16z General Partner Martin Casado to explore how AI is reshaping web development — not just through faster code generation, but by fundamentally shifting how we think about building for the web. At the center of this shift is Agent Experience (AX), a new paradigm where AI agents aren’t just tools, but active participants in development, shaping both the creative process and the underlying infrastructure.Matt shares how Netlify is evolving to meet this future, why the next 100 million web developers will collaborate with AI, and what’s at stake if the web doesn’t adapt — will we see a thriving, open, AI-powered internet, or a future dominated by walled gardens?Learn more:Introducing AX: Why Agent Experience MattersFollow everyone on X:Matt BiilmannMartin Casado
