The Build - EP 01 - OpenAI and the OS of your life in a device.

In this episode of The Build, Cameron Rohn and Tom Spencer analyze the OpenAI Codex Release and the IO Device Overview, placing recent product news in the context of practical AI development and startup strategy. They begin by unpacking the Codex announcement, the Jony Ive IO device conversation, and implications for agent-driven user interfaces, emphasizing Memory Systems and state persistence for on-device assistants. The conversation then shifts to developer tooling and workflows, where Langsmith and MCP tools enter as examples for agent orchestration, tracing, and evaluation; they contrast hosted deployment patterns on Vercel with backend strategies using Supabase for realtime data and user memory. They explore technical architecture decisions around modular memory models, API surfaces, and framework choices, weighing trade-offs for latency, privacy, and developer DX. Throughout, entrepreneurship insights surface on building in public, monetization paths, and community-driven open source approaches that accelerate product-market fit. Temporal markers guide listeners through prototype to production concerns, integrating examples of development tools and architecture patterns. The episode closes with a forward-looking call to builders: prioritize composable memory architectures, transparent iteration, and tooling that scales as they construct the OS-like experiences of users’ lives.
