Promptfoo Is Joining OpenAI
promptfoo.devHey HN - Michael here, co-founder of Promptfoo.
Happy to answer questions.
The one I'd ask if I were reading this: what happens to Promptfoo open source? We're going to keep maintaining it. The repo will stay public under the same license, we will continue to support multiple providers, and we'll keep reviewing PRs and cutting releases.
We started Promptfoo because there was no good way to test AI systems before shipping them. That turned into evals, then red teaming, then a broader security platform. We're joining OpenAI because this work has more impact closer to the model and infrastructure layers.
Ask me anything.
You guys absolutely rock. You've built an industry standard with Promptfoo. Keeping it open source was the right choice.
Congrats!
What convinced you this was the right moment and the right company to join?
You went from founding to acquisition in roughly a year and change.
Did something about the AI security landscape cause this offer to make sense? Or was it the impact you could have inside OpenAI? Or something else?
Thanks for your work and I really really hope the open source project stays maintained. I’ve been using it from the very beginning and it’s been great!
congrats on the deal.
