AI Tinkerers - "One-Shot"

Description:

Sam Hesson — technical founder and newly minted member of Meta's AI incubation team — joins the AI Tinkerers One-Shot podcast for a deep-dive into the custom CI/CD pipeline he built to orchestrate parallel AI agents at scale. Sam became notorious for spending $50,000 on tokens in just two months while pushing the limits of what agentic development systems can do. In this episode, he shares his complete architecture.

Sam walks through his "Token Abundance Mindset" and explains why moving beyond single-turn prompting is the key to unlocking a fully automated, multi-agent development workflow. From structuring your codebase for AI readiness to running adversarial LLM judges that self-heal pull requests, this is one of the most technically advanced conversations we've had on the show.

Topics covered in this episode:

• The Darwinian CI/CD — running multiple parallel agents in competition to produce the best pull request
• LLM Judge — rubric-based quality control and adversarial agents for self-healing PRs
• AI Dev Readiness — DB seeding, snapshots, and codebase prep for reliable agent testing
• The Walk Flow — converting high-level conversations (via Meta Ray-Bans) into structured PRDs and Tech Specs
• DevPlan — generating detailed, unambiguous coding prompts that eliminate guesswork for agents

AI Tinkerers One-Shot is a podcast for builders and innovators defining the future of AI — going under the hood with the people actually shipping it.

In this conversation, Eric Simons, founder and CEO of StackBlitz, walks through one of the fastest and most consequential pivots in modern developer tooling. After nearly seven years building deep browser infrastructure and reaching roughly $700k in ARR, the company reoriented around Bolt, effectively defining the vibe-coding category and scaling past $15M ARR in a matter of months.

We go under the hood of the WebAssembly-based architecture that lets Bolt run a full Node.js environment directly in the browser, delivering near-instant feedback and fundamentally different unit economics than cloud-hosted VMs. Eric explains the specific model breakthrough that made full-stack, one-shot app generation viable, and why this moment reordered who actually builds software inside companies.

In this episode of AI Tinkerers One-Shot, Joe sits down with Andrew Baker—serial builder, former Twilio engineer, and hands-on experimenter in agentic systems—to explore the rapidly evolving frontier of browser automation and AI-driven agents.

Andrew shares how his journey began with simple scripting experiments and gradually evolved into sophisticated browser agents capable of handling complex, real-world workflows. One standout example: an airline seat selector that used browser agents to secure optimal seats for frequent flyers—highlighting both the power and the limitations of today’s tooling.

Along the way, Andrew breaks down the practical challenges builders face when working with browser agents at scale:

• Vision model accuracy and UI interpretation

• DOM complexity and brittle page structures

• Authentication hurdles and session persistence

• The real economics of running large-scale automations

The conversation then shifts to “Claude Draws,” Andrew’s playful yet technically impressive side project that brings the classic 90s app Kid Pix into the age of AI. He explains how he wired up a remote PC, streamed sound output, and carefully crafted prompts that allow Anthropic’s browser agent to control a nostalgic art application—brushes, stamps, chaos, and all. The result is both a technical deep dive and a reminder that creativity is often where agentic tooling shines most.

Joe and Andrew also zoom out to examine the broader ecosystem shaping the future of browser-native agents. They discuss why UI accessibility matters for agents, how frameworks like Stagehand and Playwright are transforming automation workflows, and why personal evaluation benchmarks are becoming essential for builders pushing these systems beyond demos and into real usage.

In this episode of AI Tinkerers One-Shot, Joe sits down with Steve Yegge—engineer and creator of the Beads framework—to explore how open source tools are transforming the way we build with AI. Steve shares the story behind Beads, a new framework that gives coding agents memory and task management, enabling them to work longer, smarter, and more autonomously. From his days at Amazon and Google to leading engineering at Sourcegraph, Steve reveals how Beads is already reshaping developer workflows and why it’s gaining hundreds of contributors in just weeks.

What you’ll learn:

- How Beads gives coding agents “session memory” and lets them manage complex, multi-step projects.

- Why Steve believes the future of engineering is about guiding and supervising AI—rather than just writing code.

- The evolution from chaotic markdown files to structured, issue-based workflows.

- Techniques for multimodal prompting, automated screenshot validation, and “landing the plane” for session cleanup.

- The challenges and breakthroughs in deploying AI tools at scale within organizations.

- How Beads and similar frameworks are making it easier for both junior and senior developers to thrive in the age of AI.

Whether you’re a developer, tinkerer, or just curious about the next wave of AI-assisted coding, this deep dive with Steve Yegge will show you what’s possible now—and what’s coming next.

In this episode of AI Tinkerers One-Shot, Joe talks with Axel Peytavin, Co-founder & CEO of Innate, about his mission to create robots that aren’t just functional, but truly responsive companions. From his early start coding at age 11 to building one of the first GPT-4 Vision-powered robots, Axel shares how his team is creating an open-source robotics kit and one of the first agentic frameworks for robots — giving developers the tools to teach, customize, and build the next generation of embodied AI.

What you’ll learn:

- Why Axel believes “robots that feel alive” are the future — beyond flashy demos of backflips and kung fu.

- How Innate is making robotics accessible with an open-source hardware and SDK platform.

- The breakthroughs (and roadblocks) in fine motor manipulation, autonomy, and real-time learning.

- How teleoperation, deep learning, and reinforcement learning are shaping the next era of household robots.

- Axel’s vision for robots as companions: cleaning, tidying, assisting — and even calling for help in emergencies.

Whether you’re a tinkerer, developer, or just curious about how soon robots will fold your laundry, this deep dive shows what’s possible now — and what’s coming next.

Learn how to demystify large language models by building GPT-2 from scratch — in a spreadsheet. In this episode, MIT engineer Ishan Anand breaks down the inner workings of transformers in a way that’s visual, interactive, and beginner-friendly, yet deeply technical for experienced builders.

What you’ll learn:

• How GPT-2 became the architectural foundation for modern LLMs like ChatGPT, Claude, Gemini, and LLaMA.

• The three major innovations since GPT-2 — mixture of experts, RoPE (rotary position embeddings), and advances in training — and how they changed AI performance.

• A clear explanation of tokenization, attention, and transformer blocks that you can see and manipulate in real time.

• How to implement GPT-2’s core in ~600 lines of code and why that understanding makes you a better AI builder.

• The role of temperature, top-k, and top-p in controlling model behavior — and how RLHF reshaped the LLM landscape.

• Why hands-on experimentation beats theory when learning cutting-edge AI systems.

Ishan Anand is an engineer, MIT alum, and prolific AI tinkerer who built a fully functional GPT-2 inside a spreadsheet — making it one of the most accessible ways to learn how LLMs work. His work bridges deep technical insight with practical learning tools for the AI community.

Key topics covered:

• Step-by-step breakdown of GPT-2 architecture.

• Transformer math and attention mechanics explained visually.

• How modern LLMs evolved from GPT-2’s original design.

• Practical insights for training and fine-tuning models.

• Why understanding the “old” models makes you better at using the new ones.
