Joseph Henzi's profile on Product Hunt

About

I’m the world's first full-stack vibe coder. When ChatGPT launched in 2022, I used it to learn and build a full-stack app in 24 hours—the raw way, long before Claude Code or Cursor. I used that momentum to build the engine for nlp.henzi.org, pioneering human-in-the-loop AI fiction writing that same year. Before that, I pioneered RLHF in the health insurance space. While using ML to translate incoming documents into structured data, I directed the data science team to measure human corrections (like fixing "Jane" to "John Doe") so we could backpropagate the learning directly from those errors. Now, I focus on building fun things that humans love.

People are switching from OpenAI to Claude following Sam Altman's announcement today.

TL;DR: Anthropic refused to sign a contract with the Pentagon that would have allowed the U.S. military to use all of its models without restrictions. Anthropic insisted on an exception, and brace yourself, that its models cannot be used: 1) for mass surveillance of citizens, 2) for autonomous killing. Now the administration is threatening that if the founder of Anthropic doesn't change his mind by a certain date, they will come after him.

Google, OpenAI, and Musk (Grok) have all signed the contract.

Following Sam Altman's announcement over the past few hours, people have been speaking out massively about cancelling their OpenAI subscriptions and subscribing to Claude.
