Two days ago, OpenAI acquired Promptfoo — the AI security platform trusted by more than a quarter of Fortune 500 companies to hack-test their AI systems before deployment. This isn't a minor acqui-hire. It's the clearest signal yet of where the AI industry is headed.

In this episode:

What Promptfoo actually does: automated red-teaming, adversarial attack generation, the agentic reasoning loop, and how it tests fifty-plus vulnerability types from prompt injection to data exfiltration
The founding story: how Discord's LLM engineering lead realized AI security tools were built for a different era
Why OpenAI needed this now: Frontier, agentic AI risks, and the enterprise trust gap
How this fits with the OpenClaw hire, the io acquisition, and OpenAI's broader full-stack platform strategy
What it means for AI security startups, open source communities, and Anthropic's competing approach

The big takeaway: the real competition in AI isn't about who has the smartest model — it's about who can make enterprises trust that model enough to hand it real power.
