On today’s AI Basics, Temporal co-founder and CEO Samar Abbas says the problem isn’t with the model at all. You’re missing a harness, the layer that keeps an AI agent’s work durable, secure, and recoverable if/when something breaks. Temporal’s durable execution platform is used by major companies from OpenAI to Stripe to Netflix, and helps to make their long-running software reliable and interruption-free. On AI Basics, he explains why so many AI-coded prototypes die in the imagineering stage, before ever hitting production. Plus he walks Jason through Temporal’s live dashboard, to show how it gives developers full visibility into what their agents are doing at every step.
