Overview
- OpenAI will integrate Promptfoo’s automated red‑teaming, security evaluation and risk monitoring directly into Frontier for building and operating AI coworkers.
- The 11‑person Promptfoo team, led by Ian Webster and Michael D’Angelo, will join OpenAI to make security testing part of development workflows and compliance reporting.
- OpenAI says it will continue Promptfoo’s open‑source CLI and library, which enterprises use to test applications and compare models across providers.
- Financial terms were not disclosed, while PitchBook data shows Promptfoo raised about $23 million and carried a post‑money valuation near $86 million in 2025.
- Coverage notes concern that Promptfoo may lose its vendor‑neutral standing for auditing OpenAI models even as customers gain built‑in safeguards within Frontier.
